Photodiagnosis Photodyn Ther 2024; 46:104050. [PMID: 38548040 DOI: 10.1016/j.pdpdt.2024.104050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2024] [Revised: 03/08/2024] [Accepted: 03/13/2024] [Indexed: 05/03/2024]
Abstract
OBJECTIVE The aim was to systematically review clinical studies that investigated the efficacy of antimicrobial photodynamic therapy (aPDT) in reducing oral yeasts growth (OYG) in individuals wearing implant overdentures (IO). METHODS The focused question was "Is aPDT effective in reducing OYG in patients wearing IO?" Literature search was performed in accordance with PRISMA guidelines. Indexed databases were searched without time and language restrictions up to and including January 2024. Clinical studies were included; and letters to the Editor, case-reports/case-series, perspectives/commentaries, in-vitro/ex-vivo studies, studies on animal models and expert opinions were excluded. The risk of bias was also assessed. RESULTS Two clinical studies were included and processed for data extraction. The study population comprised of 100 (mean age: 58.5 years) and 53 (mean age: 58.5 years) individuals. The numbers of males and females included in these studies ranged between 33 and 35 males and 18-67 females, respectively. In both studies, follow-up evaluations were performed after 60 days. In both studies, aPDT was performed using a 660 nm diode laser at a power of 100 mW and using methylene-blue as photosensitizer. Results from both studies showed that aPDT is effective in significantly reducing oral yeasts CFU/ml and improvement of OHRQoL of individuals using IO. CONCLUSION The aPDT is useful in reducing OYG on IO; however, further well-designed and power-adjusted studies are needed in this area of research.

Abstract
Keratitis is corneal inflammatory disease which may be caused by several reason such as an injury, allergy, as well as a microbial infection. Besides these, overexposure to ultraviolet light and unhygienic practice of contact lenses are also associated with keratitis. Based on the cause of keratitis, different lines of treatments are recommended. Photodynamic therapy is a promising approach that utilizes light activated compounds to instigate either killing or healing mechanism to treat various diseases including both communicable and non-communicable diseases. This review focuses on clinically-important patent applications and the recent literature for the use of photodynamic therapy against keratitis.

Antimicrobial photocatalysis using bio-hydrothermally synthesized Zinc oxide nanoparticles in the management of periodontitis: a prospective split-mouth, double-blind, randomized, controlled clinical trial. J Appl Oral Sci 2023; 31:e20230271. [PMID: 38126579 PMCID: PMC10786455 DOI: 10.1590/1678-7757-2023-0271] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 09/15/2023] [Accepted: 10/22/2023] [Indexed: 12/23/2023] Open
Abstract
BACKGROUND The antimicrobial activity of metallic nanoparticles (NPs) has been confirmed to fight a broad spectrum of microorganisms, through antimicrobial effects that are amplified when these particles are irradiated with light of the proper wavelength. This is the first study to use phytoconjugated Zinc oxide (ZnO) NPs containing traces of active biomolecules derived from Emblica officinalis (E. officinalis) plant extract in antimicrobial photocatalysis (PCT) during non-surgical periodontal therapy. OBJECTIVES This study aimed to evaluate the effects of repeated PCT application in the treatment of periodontitis, using a gel containing bio-hydrothermally synthesized ZnO NPs and visible light as an adjunct to scaling and root planing (SRP). METHODOLOGY In total, 16 systemically healthy volunteers with stage 3 grade B generalized periodontitis were recruited for this prospective double blind, randomized placebo-controlled trial. After receiving SRP, the subjects received the following interventions in a split-mouth design at baseline, 1 week and 1 month: Group 1 - Placebo gel + Sham PCT; Group 2 - Nano ZnO gel + Sham PCT; Group 3 - Placebo gel + PCT; and Group 4 - Nano ZnO gel + PCT. The site-specific profile of Porphyromonas gingivalis in the subgingival plaque and clinical parameters (Plaque Index, Gingival Index, Gingival Bleeding Index, Probing pocket Depth and Clinical Attachment Level) were assessed at baseline, 1 month and 3 months. RESULTS All interventions tested caused participants' clinical and microbiological parameters to generally improve after 3 months. Subjects who received the Nano ZnO gel + PCT combination showed a sustained and progressive improvement in their treatment outcomes, a result that presented statistically significant differences from the outcomes obtained through the remaining interventions, at all time points during the study period. CONCLUSIONS The repeated application of PCT using bio-hydrothermally synthesized ZnO NPs can effectively complement SRP in the non-surgical treatment of Periodontitis.

Kattan HF. The efficacy of antimicrobial photodynamic therapy in the disinfection of coronal and radicular dentine of primary teeth: A systematic review and meta-analysis. Photodiagnosis Photodyn Ther 2023; 44:103697. [PMID: 37473792 DOI: 10.1016/j.pdpdt.2023.103697] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Revised: 07/03/2023] [Accepted: 07/07/2023] [Indexed: 07/22/2023]
Abstract
BACKGROUND Optimal endodontic disinfection by means of conventional root canal treatment of primary teeth remains a challenge. Recently, antimicrobial photodynamic therapy (aPDT) has been proposed as an adjunct to conventional endodontic treatment for microbial disinfection. The purpose of this review is to critically appraise and synthesize the currently-available evidence about the antimicrobial efficacy of aPDT (antimicrobial photodynamic therapy) when used as an adjunct to traditional root canal therapy. MATERIALS AND METHODS The focused question was ''In primary teeth needing root canal treatment (participants), is adjunct aPDT (intervention) more effective in disinfecting coronal and radicular dentine (outcomes) than root canal treatment alone (control)?'. The electronic research databases PubMED/Medline, ISI Web of Knowledge, Embase and CENTRAL (Cochrane Central Register of Controlled Trials) using relevant keyword phrases including 'antimicrobial photodynamic therapy', 'primary teeth', 'deciduous teeth', and 'endodontic treatment'. Original studies that described endodontic treatment of primary teeth or dentine using aPDT in comparison to conventional endodontic treatment were included. Case reports, reviews and other non-comparative studies were excluded. The literature search and quality assessment were carried out by two reviewers independently. RESULTS Ultimately, 9 studies were included in this review. Overall, majority of the studies concluded that adjunct aPDT improves the antimicrobial efficacy of conventional root canal therapy. However, several sources of bias were found in the studies. CONCLUSION Within the limitations of the studies, it is concluded that aPDT is a suitable adjunct to improve the disinfection of conventional root canal treatment. However, future studies should focus on the clinical outcomes, in relation to the reduction of microbial counts to ascertain the efficacy of aPDT in disinfection of primary dentine.

Abstract
Objective: This 1-year prospective clinical trial was designed to assess the microbial, clinical, radiographic, and prosthetic parameters after disinfection of the implant abutment connection using Er,Cr:YSGG (erbium, chromium-doped: yttrium, scandium, gallium, and garnet) and Nd:YAG (neodymium-doped yttrium, aluminum, garnet). Materials and methods: All the patients were divided into four groups; Group I: Nd:YAG laser, Group II: Er,Cr:YSGG laser, Group III: 0.2% chlorhexidine (CHx), and Group IV: steam disinfection. Peri-implant parameters assessed included peri-implant bleeding scores (PIBS), peri-implant plaque scores (PIPS), peri-implant pocket depth (PIPD), and crestal bone loss (CBL). The peri-implant plaque samples were acquired to perform microbiological analysis to assess Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia, respectively. All measurements were completed at baseline, 6 months, and 12 months postsurgery. Multiple groups were compared with the help of the Bonferroni post-hoc adjustment test (p < 0.01). Logistic regression models were utilized to assess the association between age, oral hygiene practices (brushing and flossing), and duration of implant function. Results: At the baseline level, there were no discernible differences in the peri-implant parameters between the study groups (p > 0.05). At the 6-month (p < 0.01) and 12-month (p < 0.001) follow-ups, all four study groups demonstrated a significant improvement in PIPS and PIBS, with no significant differences between the groups at baseline (p > 0.05). Based on an intergroup comparison, Group I (Nd:YAG) showed a significant decrease in PIBS when compared with the other groups. Group II showed a considerable decrease in PIPD and enhancements in CBL when compared with Groups I, III, and IV (p < 0.01). At the 6- and 12-month follow-up periods, P. gingivalis and T. denticola reduction were found to be statistically higher in Group II, whereas P. gingivalis and T. forsythia mean log CFU/mL were found to be statistically higher in Group I. Conclusions: Nd:YAG and Er,Cr:YSGG lasers both outperformed CHx and steam disinfection in terms of clinical, peri-implant, and prosthetic results when used to clean implant abutments.

Photodiagnosis Photodyn Ther 2023; 43:103643. [PMID: 37270045 DOI: 10.1016/j.pdpdt.2023.103643] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 05/27/2023] [Accepted: 05/31/2023] [Indexed: 06/05/2023]
Abstract
PURPOSE This study evaluated the impact of Fox Green (FG) against methylthioninium chloride (MTC)-facilitated photodynamic therapy (PDT) as an adjunctive to manual scaling (MS) on the peri‑implant clinical and cytokine parameters in type-2 diabetes mellitus (DM) patients with peri‑implantitis. METHODS Patients were divided into group-A comprising 13 patients who received adjunctive FG-PDT using a diode laser (wavelength: 810 nm; irradiation power: 300 mW; irradiation time: 30 s; fluence: 56 Jcm-2), group-B comprising 12 patients who received adjunctive MTC-PDT using a diode laser (wavelength: 660 nm; irradiation power: 100 mW; irradiation time: 120 s/site; fluence: 30 Jcm-2), and group-C comprising 13 patients who received MS alone [control group]). After diagnosing the diabetics with peri‑implantitis (established on eligibility criteria), a structured questionnaire was used to gather the information of the participants. Plaque (PS) and bleeding scores (BS), along with peri‑implant probing scores (PPS) and peri‑implant bone loss (PIBL), together with immunological variables (interleukin [IL]-6, tumor necrosis factor-alpha [TNF-α], and advanced glycation end products [AGEs]) were measured in all study group participants at baseline, 3-month, and 6-month follow-ups. RESULTS A significant reduction was observed for PS, BS, and PPS within all tested groups at each follow-up visits compared from their baseline values (p<0.05). However, a substantial decrease in PIBL was observed in all study group patients at 6-month follow-up as compared to 3-month follow-up (p<0.05). Regarding the levels of IL-6 and TNF-α, a substantial reduction was observed in all study groups until 6-month from their baseline scores (p<0.05). However, no changes were observed in the levels of AGEs in any group at either visit (p>0.05). CONCLUSION In DM patients with periimplantitis, adjunctive FG-PDT and MTC-PDT exhibited comparable outcomes in terms of peri‑implant clinical as well as pro-inflammatory characteristics than MS alone among peri‑implantitis patients with DM.

Photodiagnosis Photodyn Ther 2023; 42:103344. [PMID: 36841279 DOI: 10.1016/j.pdpdt.2023.103344] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Revised: 02/10/2023] [Accepted: 02/14/2023] [Indexed: 02/27/2023]
Abstract
BACKGROUND This study aimed to assess the efficacy of indocyanine green (ICG)-mediated versus methylene blue (MB)-mediated photodynamic therapy (PDT) as an adjunct to conventional mechanical debridement (MD) on the peri‑implant clinical, radiographic, microbiological, and immunological outcomes among diabetics with peri‑implant mucositis (pi-M). METHODS For this 3-month follow-up study, diabetics having pi-M were randomly divided into 3 groups: group-I (n = 20) subjects received only MD; group-II (n = 20) participants received ICG-mediated adjunct PDT; and group-III (n = 20) subjects received MB-mediated adjunct PDT. Peri-implant clinical (i.e., plaque index [PI], bleeding on probing [BOP], probing depth [PD]), radiographic (crestal bone loss [CBL]), microbiological (Fusobacterium nucleatum [F. nucleatum], Tannerella forsythia [T. forsythia], Prevotella intermedia [P. intermedia], Porphyromonas gingivalis [P. gingivalis], Aggregatibacter actinomycetemcomitans [A. actinomycetemcomitans]), and immunological (interleukin [IL]-6, IL-1β, tumor necrosis factor-alpha [TNF-α]) outcomes were assessed at baseline and 3-month follow-up. RESULTS Mean changes between baseline and 3-month follow-up in peri‑implant clinico-radiographic parameters were significantly different between control (PI: 12.42±21.80%; BOP: 12.10±19.30%; PD: 0.45±0.41 mm; CBL: 1.10±1.02 mm) and test groups (ICG-mediated PDT [PI: 26.55±25.80%; BOP: 28.77±29.24%; PD: 0.84±0.62 mm; CBL: 1.98±1.85 mm] and MB-mediated PDT [PI: 27.24±26.15%; BOP: 27.71±28.16%; PD: 0.85±0.63 mm; CBL: 1.95±1.80 mm]), however comparable differences were observed in peri‑implant PI, BOP, PD, and CBL between group-II and group-III participants (p>0.05). The proportions of T. forsythia were significantly reduced in group-II (4.78 × 104 colony-forming unit per milliliter [CFU/mL]) and group-III (4.76 × 104 CFU/mL) as compared to group-I (-4.40 × 103 CFU/mL) at 3-month follow-up (p = 0.02). No statistically significant differences were observed between the study groups regarding the proportions of the other assessed target bacterial species. For IL-6 (group-I: 210±108; group-II: 298±165; group-III: 277±121 pg/mL; p = 0.03), IL-1β (group-I: 101±95; group-II: 84±98; group-III: 86±74 pg/mL; p = 0.02), and TNF-α (group-I: 336±121; group-II: 385±210; group-III: 366±198 pg/mL; p = 0.03) peri‑implant sulcular fluid [PISF] levels, all three study groups demonstrated statistically significant reduction at 3-month follow-up. CONCLUSIONS ICG-mediated and MB-mediated adjunctive PDT showed statistically significant improvements in peri‑implant clinical, radiographic, microbiological, and immunological parameters as compared to conventional MD alone at 3-month follow-up among diabetics with pi-M. However, comparable outcomes were demonstrated by ICG-mediated and MB-mediated adjunctive PDT regarding the assessed peri‑implant parameters.

Abstract
BACKGROUND The present report assessed the efficacy of curcumin-mediated photodynamic therapy (CUR-mediated PDT) as an adjunct to antifungal gel treatment by evaluating the salivary interleukin-6 (IL-6) and matrix metalloproteinases-8 (MMP-8) levels together with Candida species counts in denture stomatitis (DS) patients. METHODS In total, 50 DS subjects were randomly categorized into 2 groups: Group-1: subjects who received the antifungal gel treatment and Group-2: participants who received CUR-mediated PDT. The Sabourad Dextrose Agar and CHROMAgar were utilized for evaluating Candida species counts, while the Enzyme-Linked Immunosorbent Assay was employed to estimate the salivary levels of IL-6 and MMP-8. All clinical evaluations were performed at the baseline, 1 month, and 2 months. RESULTS In total, group-2 subjects showed a significant decrease in Candida albicans (C. albicans) counts on both follow-ups (i.e., 1-month and 2-month) than group-1 participants. C. krusei count also reduced in group-2 subejcts than group-1 participants at the 2nd follow-up as compared to the baseline, nevertheless, a slight increase in C. krusei count was noticed in group-2 subjects at the 2nd follow-up than the 1st follow-up. The salivary IL-6 and MMP-8 levels in both groups reduced significantly at both follow-ups than the baseline. According to the stepwise logistic regression analysis, no statistically significant correlation was observed between Candida species count and other parameters such as age and gender of the patient, duration of DS, and frequency of treatment(s). CONCLUSION CUR-mediated PDT is an efficaciousness therapeutic modality for alleviating Candida species counts on the surface of denture and the palatal mucosa, as well as improving the salivary IL-6 and MMP-8 levels in DS patients.

Effect of Low-Level Laser Therapy on Early Wound Healing and Levels of Inflammatory Mediators in Gingival Crevicular Fluid Following Open Flap Debridement. Cureus 2023; 15:e34755. [PMID: 36909061 PMCID: PMC9999105 DOI: 10.7759/cureus.34755] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Accepted: 01/24/2023] [Indexed: 02/11/2023] Open
Abstract
Introduction Low-level laser therapy (LLLT) has a beneficial effect on pain relief and wound healing. This study aims at a clinical evaluation of early wound healing and a biochemical evaluation of inflammatory mediators in gingival crevicular fluid (GCF) following LLLT with an open flap debridement (OFD) in periodontal therapy. Material and methods This randomized controlled trial included 40 chronic periodontitis patients with bilateral attachment loss, pocket depths of 5 mm affecting at least two quadrants, and radiographic evidence of horizontal bone loss. 120 control sites were randomly selected to receive OFD, and contralateral 120 test sites received bio-stimulation with a diode laser (890 nm) after OFD. The wound healing index was recorded at the 1st and 2nd weeks, and clinical parameters such as the plaque index, gingival index, pocket probing depth, clinical attachment level, and GCF inflammatory mediators were evaluated at baseline, 3, and 6 months. Results From the start of the study to 6 months later, there was a statistically significant drop in plaque index, gingival index, probing pocket depth, and gain clinical attachment levels in both groups. However, when the two groups were compared, there were no significant differences at any time intervals. GCF inflammatory mediators tumor necrosis factor (TNF) alpha and matrix metalloproteinases (MMP-8) decrease, and osteoprotegerin (OPG) levels increase in both the test group and control group from baseline to 3 months and 6 months. In intergroup comparisons, there was a statistically significant reduction in the test group as compared to the control group at 6 months. There was a decline in gingival crevicular fluid - interleukin-6 (GCF IL-6) levels from baseline to 3 months and 6 months in both the groups but when analysed statistically, the results were not significant on intergroup and intragroup comparison at any time interval. The Landry Wound Healing Index values in the 1st and 2nd weeks were showing statistically significant improved healing in the test group as compared to the control group. There was significantly better wound healing at sites where a diode laser was used. Conclusion LLLT increases early wound healing after periodontal surgical procedures.

Antibacterial efficiency of adjuvant photodynamic therapy and high-power diode laser in the treatment of young permanent teeth with chronic periapical periodontitis. A prospective clinical study. Photodiagnosis Photodyn Ther 2022; 41:103129. [PMID: 36156313 DOI: 10.1016/j.pdpdt.2022.103129] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2022] [Revised: 09/11/2022] [Accepted: 09/19/2022] [Indexed: 02/05/2023]
Abstract
BACKGROUND The study aimed at determining antibacterial efficiency of adjuvant photodynamic therapy (PDT) and high-power diode laser (DL) in the treatment of chronic periapical periodontitis (CPP) in young permanent teeth. METHODS Forty-four young permanent teeth with CPP were randomly divided into three groups (PDT, DL and control). Each tooth underwent standard chemo-mechanical treatment, while within tested groups was additionally treated by PDT or DL. Bacterial identification and quantification were provided by MALDI-TOF spectrometry and plate counting assay, performed after accessing the canal, following chemo-mechanical preparation, and after PDT or DL procedure where applicable. RESULTS Thirty-nine young permanent teeth with CCP (patients age 9.77 ± 1.43) completed the study. Before the treatments, 202 isolates belonging to 13 genera/species, including Streptococcus (36), Actinomyces (34), Peptostreptococcus micros (27), Veillonella (25) and Enterococcus faecalis (22), were recovered. Chemo-mechanical treatment reduced CFU count in the all three groups (p < 0.001), but complete eradication was not observed for any of isolated species. Adjuvant PDT and DL completely eradicated isolates of 8 and 6 bacterial genera/species, resulting in complete bacterial elimination from 53.8% and 30.8% of root canals, respectively. In the rest canals, total Δlog CFUs were 4.71 and 4.58. CONCLUSION The results indicated that both PDT and DL could be performed as adjuvants to standard endodontic treatment of the young permanent teeth with CPP.

Clinical Efficacy and Safety of Antimicrobial Photodynamic Therapy in Residual Periodontal Pockets during the Maintenance Phase. Pharmaceuticals (Basel) 2022; 15:ph15080924. [PMID: 35893748 PMCID: PMC9332381 DOI: 10.3390/ph15080924] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2022] [Revised: 07/19/2022] [Accepted: 07/24/2022] [Indexed: 02/04/2023] Open
Abstract
Antimicrobial photodynamic therapy (a-PDT) in combination with scaling root planing (SRP) is more effective at improving periodontal status than SRP alone. However, the effectiveness of a-PDT in combination with irrigation for patients undergoing periodontal maintenance has not been clarified. This study evaluated the efficacy and safety of a-PDT in the maintenance phase. Patients who had multiple sites with bleeding on probing (BOP) and periodontal probing depth (PPD) of 4–6 mm in the maintenance phase were treated with a split-mouth design. These sites were randomly assigned to one of two groups: the a-PDT group and the irrigation group. In the a-PDT group, the periodontal pockets were treated with light-sensitive toluidine blue and a light irradiator. In the irrigation group, the periodontal pockets were simply irrigated using an ultrasonic scaler. After 7 days, the safety and efficacy of a-PDT were assessed. The mean PPD of the a-PDT group had reduced from 4.50 mm to 4.13 mm, whereas negligible change was observed in the irrigation group. BOP significantly improved from 100% to 33% in the PDT group, whereas it hardly changed in the irrigation group. No adverse events were observed in any patients. a-PDT may be useful as a noninvasive treatment in the maintenance phase, especially in patients with relatively deep periodontal pocket.

A Novel Technique for Disinfection Treatment of Contaminated Dental Implant Surface Using 0.1% Riboflavin and 445 nm Diode Laser—An In Vitro Study. Bioengineering (Basel) 2022; 9:bioengineering9070308. [PMID: 35877359 PMCID: PMC9311919 DOI: 10.3390/bioengineering9070308] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Revised: 07/06/2022] [Accepted: 07/09/2022] [Indexed: 11/16/2022] Open
Abstract
Background: Antimicrobial photodynamic therapy (PDT) has been introduced as a potential option for peri-implantitis treatment. The aim of this study is to evaluate the antimicrobial effect of a novel technique involving a combination of 445 nm diode laser light with 0.1% riboflavin solution (used as a photosensitizing dye) as applied on a bacterial–fungal biofilm formed on implants and to compare the performance of this technique with that of the commonly used combination of 660 nm diode laser with 0.1% methylene blue dye. Methods: An in vitro study was conducted on 80 titanium dental implants contaminated with Staphylococcus aureus (SA) and Candida albicans (CA) species. The implants were randomly divided into four groups: negative control (NC), without surface treatment; positive control (PC), treated with a 0.2% chlorhexidine (CHX)-based solution; PDT1, 660 nm (EasyTip 320 µm, 200 mW, Q power = 100 mW, 124.34 W/cm2, 1240 J/cm2) with a 0.1% methylene blue dye; and PDT2, 445 nm (EasyTip 320 µm, 200 mW, Q power = 100 mW, 100 Hz, 124.34 W/cm2, 1.24 J/cm2) with a 0.1% riboflavin dye. Results: The PDT1 and PDT2 groups showed greater reduction of SA and CA in comparison to the NC group and no significant differences in comparison to the PC group. No statistically significant differences between the PDT1 and PDT2 groups were observed. Conclusions: A novel antimicrobial treatment involving a combination of 445 nm diode laser light with riboflavin solution showed efficiency in reducing SA and CA biofilm formation on dental implant surfaces comparable to those of the more commonly used PDT treatment consisting of 660 nm diode laser light with methylene blue dye or 0.2% CHX treatment.

Abstract
Background: Immediate implant is a subtype of implant that is placed following tooth extraction within the socket without further delay. These implants are known to preserve the alveolar bone and minimize the total number of surgical interventions in a patient. 4 Photodynamic therapy (PDT) augments nonsurgical periodontal therapy using antibacterial mechanisms. PTD can be more effective in conjunction with scaling and root planing (SRP). The aim of this study is to assess the effects of PDT on the early outcomes of implants placed on patients with periodontitis with and without SRP at 9 months of follow-up. Materials and methods: A total of 23 implants were placed in 14 patients, with 11 in the test group and 12 in the control group. SRP was carried out prior to immediate implant placement in control sites, and PDT adjunctive to SRP (SRP + PDT) was performed in test sites before immediate implant placement. Plaque index, gingival index, probing pocket depth, clinical attachment level, and radiovisiographs were procured at baseline, 3 months, 6 months, and 9 months. Primary stability was examined at the time of implant placement, and the healing index was recorded a week later. Results: At the end of the 9 months of the study period, (SRP + PDT) group had a mean marginal bone loss of 0.95 mm, and the control group had 1.08 mm. Clinical parameters such as plaque index, gingival index, clinical attachment level, and probing depth showed definitive improvement after 9 months, compared with the baseline, but when the test and control groups were compared, the difference was statistically significant for plaque index and probing depth. The implants in both groups were followed up for a period of 9 months. There was an improvement in marginal bone loss but was not statistically significant. The survival of immediate implants in the PDT group was not different from those in the scaling and root planing group. Conclusion: The effect of PTD can be beneficially used as an adjunct to SRP. However, the effects were not significant. Photodynamic therapy can be effectively used as an adjunct to SRP owing to the better outcomes using PDT.

Abstract
BACKGROUND AND AIMS Vacuum-formed retainers (VFRs) are widely used in dental practices because of their superior esthetics. However, simultaneous maintenance of their hygiene, mechanical and optical properties is challenging. This study aimed to evaluate and compare the disinfection efficacy of antimicrobial photodynamic therapy (aPDT), chlorhexidine (CHX), sodium hypochlorite (NaOCl) and water over VFRs specimens, along with their effect on flexural strength and color stability. MATERIALS AND METHODS Fabricated VFRs of thicknesses 1 mm and 2 mm were contaminated with S. mutans and C. albicans. Brain Heart Infusion agar was used to seed Streptococcus Mutans whereas Candida Albicans was seeded in Sabourand Dextrose Agar. The contaminated retainers were divided into four groups and decontaminated using four different treatment protocols: aPDT, CHX, NaOCl and water, with 10 specimens per group. Microbial viability following decontamination, was assayed using MTT. To assess the color stability, pre and post decontamination color difference of 10 specimens was recorded using a spectrophotometer by blinding technique. The flexural strength of 10 specimens was measured using a universal testing machine by a standardized 3-point flexural strength (FS) test. RESULT aPDT showed the highest reduction in the viability of S. mutans (28%) and C. albicans (20%) species in 1 mm thickness group while the second highest reduction following disinfection with CHX (40%) in followed by NaOCl disinfection (50%). On comparison between 1 mm and 2 mm, a statistically significant difference was noted for S. mutans in aPDT (p = 0.033) and NaOCl (p = 0.028) groups, and for C. albicans, a significant difference was noted within NaOCl (p = 0.001) and CHX (p = 0.043) groups. For FS, a statistically significant difference (p < 0.05) was observed between aPDT and the rest of the groups, whereas there was no statistically significant difference in the flexural strength between the CHX, NaOCl and water groups (p > 0.05) in both 1 mm and 2 mm specimens. Between 1 mm and 2 mm specimens, no statistically significant difference in the mean color difference was noted after any disinfection protocol (p > 0.05). CONCLUSION Antimicrobial photodynamic therapy showed a remarkable reduction in candidal and bacterial viability over VFRs. aPDT treated VFR specimens showed increased flexural strength and a higher color difference post treatment compared to other reagents.

Abstract
AIM The present study aimed to appraise the effect of Diode laser (DL), riboflavin, and curcumin on the bond strength of adhesive restorative material and the effects of pretreatment on microleakage scores. MATERIAL AND METHODS Ninety caries-free human permanent premolars were obtained and disinfected. All specimens were mounted till CEJ. To provide standardization, a 2 × 2 mm flat non-carious cervical lesion (NCCL) dentin surface was exposed. This was followed by dentin surface roughening/cervical groove preparation with a round bur. After tooth surface preparation, ninety specimens were divided arbitrarily into three groups. Group 1: NCCL exposed to DL; group 2: NCCL pretreated with riboflavin photosensitizer (RFP) and group 3 pretreated with curcumin photosensitizer (CP). All the three groups were further divided into two subgroups A1, A2, B1, B2, C1, and C2 based on the restorative material used (n=15). Subgroup A1, B1, and C1 were restored with composite resin (CR). Subgroup A2, B2, and C2 were restored with RMGIC. Ten samples from each subgroup were evaluated for shear bond strength (SBS) testing under a universal testing machine (UTM). Five from each subgroup were evaluated for microleakage assessment. Bond strength and microleakage analysis were performed using analysis of variance (ANOVA) with a Post-hoc test (Tukey's post hoc test) at a significance level (p=0.05). RESULTS The group A1, DL-CR shows the highest SBS (16.41± 0.4 MPa). However, CP-RMGIC groups demonstrated the lowest bond integrity. RFP-CR and the DL-CR group displayed comparable outcomes of SBS (p>0.05). The highest microleakage was observed with CP-RMGIC. The least microleakage was displayed by DL-CR. CONCLUSION Noncarious cervical lesions pretreated with diode laser and riboflavin photosensitizer showed better shear bond strength and reduced microleakage when bonded to composite resin than non-carious cervical lesions pretreated with curcumin.

Abstract
BACKGROUND A lot of research has been done on various disinfection modalities used to achieve an aseptic implant surface. However, the bacterial efficacy and the topographical alterations resulting from the use of these techniques have never been compared. OBJECTIVE This study aimed to evaluate and compare the disinfection efficacy and surface changes on a bacteria contaminated titanium block following application of various disinfectants. METHOD Ultrasonically cleaned titanium blocks were contaminated with Porphyromonas gingivalis and Tannerella forsythia. The infected titanium implants were randomly divided into four experimental groups and decontaminated using antimicrobial photodynamic therapy (aPDT), laser therapy, chlorhexidine and hydrogen peroxide. Bacterial viability and surface changes following decontamination were analyzed. RESULT Bacterial viability decreased in all the groups with aPDT having the highest reduction. Surface roughness remained unchanged whereas the contact angle lessened in the aPDT group. CONCLUSION aPDT could possibly be a suitable alternative to other disinfection regimen to treat periimplantitis.

Abstract
AIM The present study aims to compare and evaluate radiographic and clinical parameters along with salivary proinflammatory cytokine profiles (IL-1β - and IL-6) in obese with peri-implantitis. MATERIAL AND METHODS Obese and non-obese participants in the present study were 80. The nonobese and obese participants were scrutinized based on inclusion and exclusion criteria. All participants both obese and non-obese were subjected to full mouth mechanical debridement (MD). A single session of Photodynamic therapy (PDT) was provided to all obese participants. Clinical peri-implant parameters peri-implant plaque index (PIPI), Peri-implant bleeding on probing (PIBoP), peri-implant probing depth (PIPD) were assessed at baseline, three months, and six months. Marginal bone loss (MBL) was also assessed. Enzyme-linked immunosorbent assay (ELISA) was used to check the levels of IL-1β - and IL-6 in unstimulated whole saliva samples. All the parameters were assessed using the Kruskal Wallis test and analysis of variance (ANOVA). Overall characteristics were assessed using descriptive statistics. SPSS software was used for statistical analysis. RESULTS Clinical baseline periodontal parameters PIPI, PIBoP, PIPD, and MBL in non-obese participants were significantly lower compared to group I obese participants at baseline (p < 0.05). At 3 months follow-up PDT adjunct to MD in group 1 obese participants PIPI and PIPD were significantly lower compared to MD alone in non-obese participants PIP1 and PIPD. At 6 months follow up, non-obese participants with peri-implantitis treated with MD demonstrated PIPI and PIPD significantly lower compared to obese participants treated with PDT adjunct to MD CONCLUSION: : PDT adjunctive to MD enhanced periodontal parameters i.e., peri-implant probing depth, peri-implant plaque index, and peri-implant bleeding on probing in obese with peri-implantitis. Moreover, obese individuals with peri-implantitis demonstrated high levels of proinflammatory cytokines IL-1β and IL-6 than control.

Abstract
OBJECTIVES The aim of the present study was to evaluate the effect of photodynamic therapy(PDT) on the resin-dentin bonding interface using different illumination time. METHODS Seventy completed, isolated molar teeth were collected for this study, sixty of them were used in microtensile bond strength tests. These teeth were initially divided randomly in two main groups(n=30) by the random number table method upon the type of using illumination or not respectively. Then these groups followed by dividing each category in five subgroups(n=6): group A, group B1,group B2, group B3, group B4, group a, group b1, group b2, group b3, group b4. After different treatment, the remaining teeth were made specimens which were observed the fracture modes and interfaces under a stereomicroscope and a scanning electron microscope(SEM). The dentin permeability of the specimens were evaluated by a laser scanning confocal microscope(LSCM). To detect significance difference between means of different groups analysis of variance(ANOVA) was performed followed by LSD-t tests. RESULTS There was a significant statistical difference in the microtensile bond strength of the different illumination time of PDT between four experimental groups and the control (P<0.05). CONCLUSION With the increase of the illumination time in PDT, the bonding strength between resin and dentin decreased gradually.

Abstract
AIM The present study aimed to evaluate the impact of Photodynamic therapy (PDT) and Er,Cr:YSGG laser (ECL) adjunct to nonsurgical mechanical debridement (NSMD) in comparison to conventional NSMD in overweight individuals with peri‑implant disease on peri‑implant inflammatory parameters and cytokine levels of IL-6 and TNF-α in Peri-implant crevicular fluid (PICF) MATERIALS AND METHODS: Recruitment of volunteers was performed from the outpatient department according to predefined inclusion and exclusion criteria. Group 1 consisted of obese participants who underwent peri‑implant mechanical debridement (MD); group 2, obese participants who experienced MD adjunct to ECL, and in group 3, obese participants were treated with MD and adjunct PDT. Clinical periodontal parameters, plaque index (PI), bleeding index (BI) and probing depth (PD) along with crestal bone loss (CBL) were assessed at baseline, 3 months, and 6 months. PICF was collected to evaluate the levels of IL-6 and TNF-α. Kruskal-Wallis and Bonferroni post hoc test were employed for the comparison of peri‑implant inflammatory parameters and PICF cytokine profiles among the study groups. RESULTS Clinical peri‑implant parameters (PI, BI and PD) at baseline among subjects in group 1, group 2 and group 3 were comparable (p > 0.05). At 3 months follow up, mean scores of peri‑implant PI, BI, and PD (P <0.05) in group 1 (control) were significantly higher compared to group 2 (ECL) and 3 (PDT) (p < 0.05). At 6 months follow-up, PI and BI mean scores among groups 1, 2, and 3 were comparable (p>0.05). At 6 months participants in groups 2 and 3 noted significant difference (p<0.05) compared to baseline with no difference noted in the control group (p>0.05). CONCLUSION Photodynamic therapy and Er, Cr: YSGG adjunct to NSMD demonstrated significant improvement in peri‑implant inflammatory parameters in obese individuals. Multicentric clinical trials are suggested to extrapolate the findings of the present study.

Hydrogen peroxide potentiates antimicrobial photodynamic therapy in eliminating Candida albicans and Streptococcus mutans dual-species biofilm from denture base. Photodiagnosis Photodyn Ther 2021; 37:102691. [PMID: 34921987 DOI: 10.1016/j.pdpdt.2021.102691] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2021] [Revised: 11/10/2021] [Accepted: 12/13/2021] [Indexed: 12/30/2022]
Abstract
BACKGROUND Candida albicans (C.albicans) is the primary pathogen of denture biofilm. Moreover, it could establish a cross-kingdom relationship with bacteria to enhance its virulence and resistance to antifungal drugs. This study aimed to investigate the efficacy of antimicrobial photodynamic therapy (aPDT) in combination with hydrogen peroxide (H2O2) against C.albicans and Streptococcus mutans (S.mutans) dual-species biofilm formed on polymethyl methacrylate (PMMA) disk, and explore its involved mechanisms. METHODS C.albicans and S.mutans were grown on PMMA disk for 48 h to form biofilm and received different treatments. The treatments included:1) phosphate-buffered saline (PBS) group,2) 100 mM H2O2 group,3) aPDT group,4) aPDT+ H2O2 and 5) H2O2+aPDT group. Colony forming units (CFU), 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), and scanning electron microscope (SEM) were used to evaluate the antimicrobial effects. Extracellular polysaccharide substance (EPS) production and observation, cell permeability of biofilm, and uptake of toluidine blue O (TBO) by biofilm were assessed to investigate the involved mechanism. RESULTS There was no significant difference between PBS group and H2O2 group in viable microorganisms and metabolic activity of biofilm. The treatment protocols containing aPDT group reduced microorganism numbers and metabolic activity when compared to PBS group or H2O2 group (P<0.05). H2O2+aPDT treatment showed the highest antimicrobial efficacy in comparison with other treatments (P<0.05). Pretreatment with H2O2 could decrease EPS production and enhance cell permeability, leading to increased TBO uptake in biofilm. CONCLUSION Pretreatment with H2O2 improved aPDT efficiency in eliminating dual-species biofilm from PMMA disk by reducing EPS amount, enhancing cell permeability, and increasing TBO uptake.

Evid Based Dent 2021:10.1038/s41432-021-0208-9. [PMID: 34862461 DOI: 10.1038/s41432-021-0208-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Accepted: 08/31/2021] [Indexed: 11/08/2022]
Abstract
Purpose This meta-analysis assessed the efficacy of antimicrobial photodynamic therapy (aPDT) compared to conventional nystatin therapy (NYT) in reducing Candida colony count in patients with Candida-associated denture stomatitis (CADS) and critically appraised the available literature.Methods This meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) updated guidelines. A literature search was performed in four electronic databases to identify relevant articles up to 15 August 2021. Randomised controlled trials (RCTs) that assessed the efficacy of aPDT compared to NYT in reducing Candida colony count in patients with CADS were investigated. The weighted mean difference (MD) and 95% confidence interval were calculated. The I2 statistic was used to determine heterogeneity at the level of α = 0.10. The Cochrane risk of bias (RoB 2) tool was used to assess the risk of bias. Certainty of the evidence was determined using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) ranking system.Results Only three eligible RCTs with 141 participants were included in this systematic review and meta-analysis. Based on the pooled results, NYT compared to aPDT generally performed better in reducing Candida colony count (Log10 CFU/mL) in patients' palate and patients' denture. The included studies had a moderate risk of bias and the certainty of the evidence was low.Conclusion Although still inconclusive, based on the current evidence, aPDT may be effective in reducing Candida colony count and treating CADS. Nonetheless, it does not appear to be more effective than conventional NYT in this regard. According to the limited number of included studies, more well-designed RCTs with larger sample sizes and standardised methodology should be conducted to validate this conclusion.

Abstract
AIM The study aimed to evaluate the efficacy of Mechanical debridement (MD) with and without adjunct antimicrobial photodynamic therapy (aPDT) in the treatment of peri‑implantitis among waterpipe smokers (WPS) and non-smokers with peri‑implantitis MATERIAL AND METHODS: Participants were stratified into two groups. Group 1: Subjects who smoked water pipes for the last 2 years with peri‑implant disease were treated with aPDT adjunct to MD and group 2: Participants who did not use water pipes in the last 2 years but have periimplantitis (controls) were treated with MD only. Participants were scrutinized with peri‑implantitis (PI) in one dental implant at least based on the inclusion and exclusion criteria. Using structured questionnaire information was gathered from participants. All participants underwent mechanical debridement (MD). Participants of WPS underwent antimicrobial photodynamic therapy (aPDT). Peri implant inflammatory parameters (PI, BI, PD, and CBL) were assessed in all participant at baseline, 3 months and 6 months follow-up. Periimplant sulcular fluid was collected for assessment of bone metabolic biomarkers RANK-L and OPG. For immunological and clinical peri‑implant parameters analysis of variance (ANOVA) and Kruskal-Wallis test were used. For multiple comparisons, Bonferroni post hoc test was deployed. RESULTS Clinical periodontal parameters at baseline were significantly different in the control group PI (49.8 ± 10.5), BI(46.8 ± 7.7), and PD (5.0 ± 1.8) compared to WPS PI (56.1 ± 12.0), BI (40.9 ± 8.3), and PD (5.6 ± 1.5) (p < 0.05). At 3 months follow-up after PDT, PI (19.1 ± 7.7) and PD (3.9 ± 1.4) were significantly lower in the control group compared to WPS group PI (23.5 ± 8.4) and PD (4.5 ± 1.2) (p < 0.05). Whereas, BI of control (16.3 ± 6.8) and WPS group (17.1 ± 5.3) at 3 months follow-up was comparable (p > 0.05). At six months follow up following PDT, PI (15.7 ± 5.5) and PD (3.4 ± 1.2) was significantly lower in the control group compared to participants with water piped users PI (18.6 ± 7.4) and PD (3.9 ± 1.3) (p < 0.05). No significant difference was noted in BI in both groups (p > 0.05). Participants treated with PDT adjunct to MD demonstrated significantly reduced mean RANK-L levels at both 3 and 6 months (p<0.05). CONCLUSION aPDT adjunctive to MD improved periodontal parameters i.e., plaque index, pocket depth, and crestal bone loss along with metabolic marker RANK-L in water pipe smokers compared to non piped smokers.

Abstract
Introduction/Objectives Periodontitis comprises of a wide range of inflammatory conditions of the gums leading to soft tissue damage and attachment loss. The initiation of periodontitis constitutes a rather complex disease pathogenesis which is based on pathogenic shifts of the oral microbiota combined with the host-microbiome interactions. The severity of the periodontitis is multifactorial depending on genetic, environmental, as well as host immunity factors. Data and sources To make an inclusive analysis on the periodontitis therapeutics, reading of the recent relevant literature was carried out using the MEDLINE/PubMed database, Google Scholar and the NIH public online database for clinical trials (http://www.clinicaltrials.gov). Conclusions Tackling the inflammation associated periodontal defects can be succeeded with conventional therapy or resective and regenerative treatment. To date, the mechanical removal of the supragingival and subgingival biofilm is considered the “gold standard” of periodontal therapy in combination with the use of antibacterial compounds. The antimicrobial resistance phenomenon tends to turn all the currently applied antibacterials into “endangered species”. Ongoing efforts through the conduct of clinical trials should be focused on understanding the advantages of modern approaches in comparison to traditional therapies.

J Lasers Med Sci 2021; 12:e47. [PMID: 34733770 DOI: 10.34172/jlms.2021.47] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2020] [Accepted: 03/14/2021] [Indexed: 12/21/2022]
Abstract
Introduction: This study aimed to compare the effects of root biomodification by citric acid and antimicrobial photodynamic therapy (aPDT) with LED and laser on the proliferation of human gingival fibroblasts (HGFs). Methods: This in vitro experimental study evaluated 60 single-rooted teeth extracted due to periodontal disease. The teeth underwent scaling and root planing (SRP), and then 5 × 5 mm blocks were prepared from the cervical area of the teeth 1 mm apical to the cementoenamel junction. The blocks were divided into 4 groups (n=15 blocks): SRP alone (control), SRP + citric acid, SRP + toluidine blue (TBO) + LED light, and SRP + TBO + laser. HGFs were seeded on the surface of the samples, and the methyl thiazolyl tetrazolium (MTT) assay was performed after 24, 48 and 72 hours. Group comparisons were performed using repeated measures ANOVA, while pairwise comparisons of the time points were performed by an LSD test. Results: Cell proliferation was higher in all experimental groups at 48 and 72 hours, compared with 24 hours (P < 0.05). Cell proliferation was significantly different in the citric acid group at 24 hours (P = 0.016) and 48 hours (P = 0.015), compared with other groups. However, cell proliferation was not significantly different in the aPDT group with LED Photosan and a diode laser at 24 and 48 hours (P > 0.05). Conclusion: aPDT and citric acid can enhance the proliferation of HGFs on dentin blocks. Further studies can pave the way for their future use in the clinical setting.

Abstract
BACKGROUND Cigarette smoking in conjugation with bad oral hygiene is considered a typical predisposing factor for many oral diseases including denture stomatitis. This study investigated the effect of Rose Bengal (RB)-and Curcumin (CUR)-mediated photodynamic therapy (PDT) in comparison with nystatin therapy in the intervention of denture stomatitis in cigarette smokers. METHODS Overall, 45 habitual cigarette smokers aged ~58 years having denture stomatitis were categorized into three groups: Group-I - RB-mediated PDT, Group-II - CUR-mediated PDT, and Group-III - Nystatin therapy. The primary outcome of the interest was: counts of Candida colony from denture surface and palatal mucosa, calculated as CFU/mL, whereas the prevalence of Candida species determined in 3 research groups comprised the secondary outcome. Oral swab specimens were gathered from the denture surfaces and palatal mucosa. All clinical assessments were performed at baseline, 6 weeks, and 12 weeks. RESULTS C. albicans was the most prevalent yeast identified on both denture surfaces and palatal mucosa, followed by C. tropicalis and C. glabrata. A considerable decrease in the CFU/mL scores were observed in Group-I and Group-II at the end of the interventions and on the 12-week follow-up (p<0.05). Group-I, II, and III demonstrated clinical efficacy rates of 53%, 51%, and 49%, respectively. CONCLUSION CUR-and RB-mediated PDT was found to be as effective as topical Nystatin therapy for the intervention of denture stomatitis among cigarette smokers.

Aljamhan AS. Impact of riboflavin and curcumin mediated photodynamic therapy and Er,Cr:YSGG on microleakage of class V resin glass ionomer restorations in permanent molar teeth. Photodiagnosis Photodyn Ther 2021:102462. [PMID: 34325077 DOI: 10.1016/j.pdpdt.2021.102462] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2021] [Revised: 07/16/2021] [Accepted: 07/22/2021] [Indexed: 11/28/2022]
Abstract
PURPOSE The present study aimed to evaluate the impact of PDT using curcumin and riboflavin as photosensitizers and Er,Cr:YSGG on microleakage in class V RMGIC restorations in permanent teeth. MATERIALS AND METHODS Eighty permanent molars were investigated and randomly divided into 4 groups: control group: resin-modified glass ionomer restoration with no treatment, R-PDT: PDT with riboflavin, Cu-PDT: PDT with curcumin (Cu) and, Er,Cr:YSGG: laser application. All the teeth in each group were restored with the help of RMGIC. The samples were dipped for 24 h in 0.5 % Fuchsine solution, and subsequently fixed in acrylic resin-based molds. Microleakage scores were estimated considering both cervical and occlusal boundaries. Intergroup comparisons were made at each margin, and intragroup comparisons made at the cervical and occlusal margins. The Shapiro Wilk test was used to check the normality of the values. Whereas, the analysis of data was conducted using SPSS version 25 via the Kruskal-Wallis and Wilcoxon tests. P < 0.05 was contemplated to be statistically important. RESULTS A high frequency (95%) of the enamel walls were not penetrated when subjected to treatment with R-PDT, followed by Cu-PDT and Er,Cr:YSGG. The highest amount of microleakage was observed (55%) Cu-PDT at the site of the cavity near the cementum. The least amount of microleakage was observed in the control group. A statistically significant difference in microleakage was noted at the cervical wall (p=0.015), while no significant difference was seen at the occlusal wall (p=0.789) between the groups. A significant difference was noted at the cervical wall between the control and R-PDT group (p=0.021) and Cu-PDT group (p=0.005), respectively. A significant difference in microleakage was observed when occlusal was compared with cervical walls within each group (p<0.05). CONCLUSION Photosensitizers using riboflavin and curcumin may reduce the microleakage within the enamel surface restored with RMGIC in class V lesions that may not interfere with bonding. However, extreme caution should be taken while considering riboflavin and curcumin for class V RMGIC restorations extending to cementum surface.

Abstract
BACKGROUND The aim of this study was to compare, through clinical and microbiological analysis, the use of multiple applications of aPDT as an adjuvant therapy to non-surgical periodontal treatment of stage III and IV grade C periodontitis in type 2 diabetic (DM2) patients. METHODS Thirty-four patients with non-compensated DM2 and periodontitis were randomly divided into two groups: SRP Group (n = 17): scaling and root planing (SRP); and SRP+aPDT Group (n = 17): SRP followed by 3 consecutive aPDT applications, immediately, 48 and 96 h after in pockets with probing depth (PD) ≥5 mm. In SRP+aPDT, after 1 min of irrigation with methylene blue (10 mg/ml), the sites were irradiated with a 660 nm diode laser for 50 s (157 J/cm2, 4.7 J, 100 mW). Porphyromonas gingivalis (P. gingivalis) and Prevotella intermedia (P. intermedia) were quantified by real-time qPCR. Periodontal clinical and microbiological data (baseline, 90 and 180 days) were statistically analyzed (α = 5%). RESULTS There was a significant reduction in PD and bleeding on probing at 90 and 180 days post-treatment in both groups (p<0.05). The SRP+aPDT group presented a significant reduction in the number of residual pockets at 90 and 180 days (p<0.05). The SRP+aPDT group presented reduced PD means in deep pockets 180 days post-treatment (p<0.05). No differences were observed in P. gingivalis and P. intermedia levels (p>0.05). CONCLUSION The results of present study indicate that the use of multiples aPDT sessions as adjuvant therapy in the periodontal treatment of uncompensated diabetic patients with periodontitis promotes additional clinical benefits.

Abstract
Background Due to the limitations of scaling and root planing (SRP) in chronic periodontitis (CP) management, research has been focused on utilising additional therapies to enhance conventional treatment methods. The present systematic review is aimed to appraise the accessible scientific evidence of in vivo human studies to establish the effectiveness of adjunctive diode (λ 808- λ 980nm) laser treatment to SRP in CP. Methodology This systematic review was conducted following the PRISMA statement guidelines. The review protocol is registered in PROSPERO (CRD 42021227695). The search strategies were based on structured electronic and manual (with appropriate keywords) and were conducted to collect the applicable published data on RCTs studies (in vivo human), spanning over ten years between August 2010 and August 2020. The articles were selected to address the following research focus question: “Does diode laser (λ 808- λ 980nm) therapy have superior effects as an adjunct to SPR, compared to SRP alone, in terms of clinical or microbiological or immunological profiles in the management of CP?” Results Fifteen articles met the eligibility criteria and are included in this review. A wide range of discrepancies and inconsistencies were shown in the outcomes of the laser and SPR treatment modality, compared to SRP alone. The data on standardised study protocol, optimal laser parameters and outcome measurements were inconclusive, and a high risk of bias in the majority of the studies observed, which are crucial in establishing a homogenous and reproducible protocol. Conclusion In light of the confined evidence-based data and critical evaluation of this systematic review, the efficacy of adjunctive diode laser treatment ranging between 808 and 980nm to SRP remains debatable. The observational quality of the present systematic review was emphasised after scrutinising the available data, and an attempt to propose a laser protocol for future RCTs consideration was a great challenge due to an absence of clear and standardised recommendations in delivering a reliable laser protocol which can be replicable by future investigators. RCTs with robust methodology are warranted.

Abstract
BACKGROUND The aim of this randomized controlled clinical trial was to evaluate the efficacy of indocyanine-green mediated antimicrobial photodynamic therapy (ICG-aPDT) in the treatment of stage III grade C periodontitis in terms of clinical, microbiological, and immune-inflammatory parameters in patients with well-controlled and poorly-controlled form of type-2 diabetes mellitus (T2DM). MATERIALS AND METHODS Subjects with a diagnosis of chronic periodontitis according to the new classification and case definition of periodontitis [probing depth (PD): ≥6 mm, interdental clinical attachment loss (CAL): ≥5 mm and bone loss extending to mid-third of root and beyond (≥3 mm)] were recruited. Subjects were grouped on the basis of well-controlled and poorly-controlled diabetic status. Two subgroups were made according to the treatment modality (RSD versus ICG-aPDT/RSD) in each group. A split-mouth design was used in which one site was designated for control (RSD alone treatment) while the other contralateral site was chosen for test treatment (ICG-aPDT/RSD) in all the patients. Periodontal parameters included the measurement of plaque score (PS), bleeding on probing (BOP), probing depth (PD), clinical attachment level (CAL) and alveolar bone levels (ABL). Identification of Porphyromonas gingivalis and Tannarella forsythia through PCR was executed using species specific primers. Gingival crevicular fluid samples were then analyzed using enzyme-linked immunosorbent assay for the quantification of interleukin (IL)-17 and interferon (IFN)-γ. All the clinical, microbiological, and immunological parameters were assessed using repeated measure ANOVA for intra and inter-group comparisons. The p-value significance was set at 0.05. RESULTS The mean age of the 50 patients was 44.7 ± 7.4 years. Systemic parameters suggest no significant change between the times in either HbA1c or serum CRP levels in any of the groups. A statistically significant reduction for BOP was noted for ICG-aPDT group for non-diabetic subjects at 3 months follow up only, while a significant reduction was seen at both 3 months and 6 months among well-controlled and poorly-controlled T2DM subjects (p<0.05). For PD and CAL, a significant improvement was seen for ICG-aPDT group among non-diabetic and well-controlled T2DM subjects at both 3- and 6-months follow up, while a significant reduction was seen at only 3 months among poorly-controlled T2DM subjects. A significant reduction was seen for ICG-aPDT group compared to RSD group for both bacteria in all the three groups at 6 months follow up (p<0.05). CONCLUSION ICG-aPDT significantly improved clinical and antimicrobial parameters in well-controlled and poorly-controlled T2DM having stage III and grade C periodontitis. Glycemic status did not have negative impact in the reduction of periodontal parameters in either types of T2DM. TRIAL REGISTRATION The present RCT was registered in the clinicaltrials.gov under the identifier: NCT04857346.

Effects of infrared light laser therapy in vivo and in vitro periodontitis models. J Periodontol 2021; 93:308-319. [PMID: 34050677 DOI: 10.1002/jper.20-0842] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2020] [Revised: 04/16/2021] [Accepted: 04/28/2021] [Indexed: 11/10/2022]
Abstract
BACKGROUND This study evaluated the effects of infrared light laser therapy (ILLT) on ligature-induced periodontitis in rats using micro-computed tomography (micro-CT), histology, fibroblast migration, and viability analysis. METHODS Forty-eight rats were randomly distributed into three groups: control (no periodontitis), PDC (periodontitis without laser therapy), and PD+L (periodontitis with laser therapy). Periodontitis was induced by ligature placement for 4 weeks. The 12-week-old rats (baseline) were subjected to laser treatment and euthanized 30 days after. After treatment, the mandibular first molars were prepared for micro-CT scanning, and histological sections were assessed as to the cementoenamel junction, alveolar bone crest, and polymorphonuclear (PMN) cell infiltration. In vitro assays were carried out to examine NIH/3T3 fibroblast viability after laser therapy. RESULTS Migration and cell viability assays revealed that the ILLT maintained fibroblast cell viability with 4 J/cm2 , reaching 100% healing. The control group (at baseline and 30 days) presented a statistically significant difference from the PDC group at 30 days in terms of distance from the cementoenamel junction to the alveolar bone crest (CEJ-ABC). The PD+L group showed a statistically substantial difference from the PDC group at 30 days in terms of trabecular thickness (Tb.Th), degree of anisotropy (DA), and closed porosity percentage (Po%). CONCLUSION ILLT seemed to preserve the bone structure in the in vivo periodontitis induction model at 30 days and did not reduce cell viability or increase fibroblast migration in vitro. The ILLT provides positive effects on mandibular bone microstructure.

Effect of ultrasonic scaling with adjunctive photodynamic therapy on the treatment of gingival inflammation among diabetic patients undergoing fixed orthodontic treatment. Photodiagnosis Photodyn Ther 2021; 35:102360. [PMID: 34052421 DOI: 10.1016/j.pdpdt.2021.102360] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Revised: 05/02/2021] [Accepted: 05/21/2021] [Indexed: 02/08/2023]
Abstract
BACKGROUND The aim of the present clinical trial was to evaluate the effect of methylene blue-mediated antimicrobial photodynamic therapy (aPDT) on the gingival and immunological parameters in diabetic adolescent patients undergoing fixed orthodontic treatment. METHODS The selected 40 participants were randomized equally into two groups; Group I (ultrasonic scaling + oral hygiene instructions) and Group II (ultrasonic scaling/oral hygiene instructions + aPDT). Serum HbA1c levels was assessed for all the participants at chairside. Plaque index (Pi), and bleeding on probing (BOP) were analyzed. Moreover, the assessment of crevicular fluid matrix metalloproteinase 8 (MMP-8) and macrophage inflammatory protein 1 alpha (MIP-1α) was performed using enzyme-linked immunosorbent assay technique. All measurements were recorded at baseline, 6 weeks, and 12 weeks follow-up periods, respectively. Intergroup comparisons for p-value were computed using Mann-Whitney test and Wilcoxon singed ranks test to compute p-value for intra-group comparisons. Stepwise logistic regression analysis was used to identify explanatory variables for reduction in plaque scores and bleeding on probing, after controlling for the effects of other covariates. Odds ratios and 95% confidence intervals were used to assess the direction and strength for associations. Significance level was set at 5% for all analyses. RESULTS All 40 individuals completed the clinical trial. There was a statistically significant reduction in Pi and BOP in both Group I and Group II from baseline to 12 weeks of follow up (P<0.05). However, there was slight reduction in the plaque scores in Group-II as compared to Group-I at 12 weeks visit (P<0.05). There was also a statistically significant difference for BOP when Group-I was compared with Group-II on 12 weeks follow up assessment (P<0.05). HbA1c assessment indicated no statistically significant difference either within or between groups at any time point (P>0.05). Both MMP-8 and MIP-1α reported a significant decrease for both Groups I and II at 6 weeks and 12 weeks follow-up periods in comparison to baseline (P<0.05). Inter-group comparison indicated a statistically significant difference noted at both 6 weeks follow up that was maintained at 12 weeks follow up (P<0.05). The logistic regression analysis revealed that even after controlling the mean BMI as a predictor, the change of biomarker levels along with the improvement in plaque scores and bleeding on probing was not significant (p> 0.05). CONCLUSION aPDT significantly improved bleeding on probing and proinflammatory biomarkers among diabetic adolescent patients undergoing fixed orthodontic therapy.

[PMID: 34033934 DOI: 10.1016/j.pdpdt.2021.102350] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2021] [Revised: 04/14/2021] [Accepted: 05/14/2021] [Indexed: 12/20/2022]
Abstract
Background This 6-months randomized controlled clinical trial aimed to assess the efficacy of indocyanine green mediated photodynamic therapy (ICG-PDT) as an adjunct to peri‑implant manual debridement (PIMD) versus PIMD alone among Diabetes Mellitus (DM) patients in the treatment of peri‑implantitis. Methods A total of 48 DM patients having 64 implants were treated with either ICG-PDT + PIMD (n = 35 implants) or PIMD alone (n = 29 implants). Clinical (probing depth [PD], bleeding on probing [BOP], and plaque index [PI]) and radiographic (peri‑implant crestal bone loss [PCBL]) peri‑implant variables were recorded. Bacterial species including Porphyromonas gingivalis and Treponema denticola were evaluated from peri‑implant plaque biofilms. Levels of interleukin (IL)-1β and IL-6 were assessed after the collection of peri‑implant sulcular fluid. All the evaluations were carried out at baseline, 3- and 6-months. The significance level was set to p < 0.05. Results All clinical parameters significantly reduced within both treatment groups (P<0.05). Intra-group comparison indicates that there was statistically significant reduction in PD and suppuration for ICG-PDT group (P<0.05). There was a statistically significant difference in the BOP between ICG-PDT and PIMD groups at both follow-up periods (P<0.001). However, there was a significant difference for PD (P = 0.001), suppuration (P = 0.01), and PCBL (P = 0.04) on 6 months follow-up between ICG-PDT and PIMD groups, respectively. Only ICG-PDT showed a significant reduction in P. gingivalis and T. denticola on both 3 months and 6 months follow-up compared to baseline. PIMD showed a statistically significant reduction only on 3 months follow-up compared to baseline. This reduction was maintained for both the species when dental implants were treated with ICG-PDT. However, PIMD failed to maintain this reduction until 6 months. Only at 3 months assessment that both treatment groups showed statistically significant reduction in IL-1β and IL-6 with no significant difference between the groups. Both biomarkers failed to maintain the reduction in both groups and significantly increased levels for IL-1β was noted at 6 months follow up Conclusion Multiple application of indocyanine-green mediated photodynamic therapy resulted in improved clinical and microbial parameters among type 2 DM subjects in the treatment of peri‑implantitis. This clinical trial was registered in the ClinicalTrials.gov Protocol Registration and Results System with registration record number: NCT04833569.

Abstract
BACKGROUND The main goal of periodontal therapy is to eliminate the spread of infection in the periodontium. Antimicrobial photodynamic therapy (aPDT) is a bactericidal method that has been recently introduced for controlling periodontal infection. The aim of this in vitro study was to evaluate the effect of aPDT using a combination of medium-power blue light-emitting diodes (LEDs) and rose bengal (RB) on selected key periodontopathogens. METHODS Porphyromonas gingivalis ATCC33277, Aggregatibacter actinomycetemcomitans ATCC29523 and Fusobacterium nucleatum ATCC10953 were used in the experiments. Each bacterial suspension was irradiated with a blue LED (BL) (450-470 nm, output power density of 1.2 W/cm2) for 20-60 s (6-18 J/cm2), treated with RB (1 min), or subjected to a combination of RB treatment and BL irradiation (40 s, 12 J/cm2). All bacterial suspensions were serially diluted, plated and incubated anaerobically or microaerobically, and the numbers of colony-forming units (CFUs) were counted on day 7. One-way analysis of variance (ANOVA) and Tukey's HSD tests were used for statistical analysis. RESULTS Treatment with BL irradiation from 6 to 18 J/cm2 did not significantly reduce the number of CFUs, whereas treatment with RB alone induced a low-to-high reduction in the bacterial CFUs in a dye concentration-dependent manner. Furthermore, the difference in the effects obtained with 16 μg/mL and 160 μg/mL RB was not statistically significant. Treatment with the BL at 12 J/cm2 combined with 160 μg/mL RB yielded maximal log reductions of 3.03, 4.2 and 2.23 in P. gingivalis, A. actinomycetemcomitans and F. nucleatum CFUs, respectively. CONCLUSION Within the limits of this study, the three periodontal pathogens, especially A. actinomycetemcomitans, were susceptible to photodynamic inactivation by the combination of the BL and RB. RB-mediated aPDT may offer a viable alternative tool for periodontal pathogen treatment, especially for A. actinomycetemcomitans eradication. aPDT may be a valuable tool for the treatment of periodontal diseases, particularly those in which A. actinomycetemcomitans is a dominating pathogen.

Abstract
PURPOSE The aim of this laboratory study was to investigate the amount of bacterial destruction through riboflavin mediated photodynamic therapy (PDT) around fixed orthodontic devices by using the two strains of bacteria Streptococcus mutans and Streptococcus sanguinis. MATERIALS AND METHODS A total of 80 metallic brackets were divided into four groups consisting of 20 brackets each. Group-I: riboflavin + LED irradiation; Group-II: riboflavin alone; Group-III: immersion in 0.2 % chlorhexidine gluconate solution and Group-IV: not submitted to any treatment. All metallic brackets were immersed in the standard bacterial solutions and incubated at 48 h. All samples were subjected to MTT assay for microbial cell viability testing after treatment. After 24 h of incubation, biofilms adhered on the mesh of metallic brackets after treatment were assessed by confocal laser microscopy. The total CFU/mL was estimated, and the results were log-transformed (log10) and analyzed using one-way analysis of variance and Tukey-Kramer test. P-value was set to <0.05 that indicated statistical significance. RESULTS The samples from group-IV showed the highest amount of relative biofilm viability compared to any other group while group-I (PDT) showed the least viability of the two bacterial strains studied (p < 0.05). Group-I showed no significant difference when compared with group-III (chlorhexidine) (p > 0.05). The biofilms on the samples from group-II and group-IV were largely viable indicating thick green staining across the mesh of the brackets. Among the group-III samples, there were predominantly dead cells as compared to the live cell staining. A considerable amount of red staining was observed with noticeable less green staining in group-I samples. CONCLUSION This laboratory investigation revealed that riboflavin mediated PDT significantly reduced the amounts of S. mutans and S. sanguinis around the orthodontic brackets.

Abstract
Biofilms have higher levels of antibiotic resistance compared to bacteria, so the alternatives are needed as therapy for diseases caused by biofilm infections. Photodynamic Therapy (PDT) has the advantage of being a safe alternative that involves molecular-level photochemical reactions. The use of different types of exogenous photosensitizers (PS) was done to compare their effectiveness. Turmeric extract containing curcumin has good effectiveness in PDT, whereas nanodoxycycline as an antibiotic has a fairly broad absorption spectrum and is effective as PS. The purpose of this study is to compare the effectiveness of photodynamic therapy on infections by Aggregatibacter actinomycetemcomitans causing periodontitis using exogenous organic and non-organic photosensitisers (PS). The A. actinomycetemcomitans biofilm had been grown on 96-well microplate for 72 hours incubation time. The samples were divided into three groups, treated with Laser diode, Laser + Turmeric Extract 0.5%, and Laser + Nanodoxycycline 0.1%. Treatment was done with a variety of exposure times: 30, 60, 90, 120, and 150 seconds. The data were analyzed using ANOVA test. The results of data analysis showed that diode laser irradiation treatment with endogenous porphyrin, diode laser with Curcumin and diode laser with nanodoxycycline produced significantly different biofilm reductions. Treatment with diode laser irradiation at various energy densities (4.15, 8.28, 12.44, 16.59, and 20.73 J/cm2) showed no significant difference in reducing bacterial biofilm. The treatment with diode and curcumin, and the treatment with diode laser irradiation and nanodoxycyclin showed a significant difference. Diode laser irradiation of 20.73 J/cm2 with irradiation time of 150 seconds resulted in the greatest reduction of biofilm 14.94%, diode laser irradiation + Curcumin 47.82%, and diode laser irradiation + nanodoxycyclin 53.76%. Therefore, PDT using a diode laser combined with exogenous PS extract of curcumin and nanodoxycycline is more effective to reduce bacterial biofilms.

Efficacy of photodynamic therapy, photobiomodulation and antimicrobial agent on the shear bond strength of composite restorations to hypomineralized teeth. Photodiagnosis Photodyn Ther 2021; 33:102188. [PMID: 33497813 DOI: 10.1016/j.pdpdt.2021.102188] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2020] [Revised: 12/30/2020] [Accepted: 01/15/2021] [Indexed: 11/17/2022]
Abstract
PURPOSE The aim of this study was to investigate the adhesive bond strength and fracture analysis of resin based restorations to carious dentin of hypomineralized molars (HMs) after disinfecting with photodynamic therapy (PDT), Nd:YAG and chlorhexidine (CHX). MATERIALS AND METHODS Sixty carious HM molars were investigated. After removal of all carious infected tissue, the cavities were condition with methylene blue initiated PDT, a 1064 nm wavelength Nd:YAG laser or 2.0% CHX gel. Non-carious dentin from HM was used as a control without performing any disinfection or conditioning technique. All samples were bonded using a one-step one-coat adhesive bond over the dentin surface, packed with composite and light cured. All specimens were subjected to thermocycling at 5°C and 60°C with a dwell time of 30 s for 10,000 cycles. Bonded specimens were placed on a universal testing machine with a flat loading head. The debonded surface were viewed under light optical microscope to estimate the type of failure including adhesive, cohesive, and admixed. RESULTS The highest mean SBS was seen in the non-carious HM (control group). The mean score for control group was 17.64 ± 2.96 MPa. The lowest bond strength value was displayed for Group-PDT (11.37 ± 3.66 MPa) and Group-Nd:YAG (12.69 ± 2.45 MPa). Affected dentin disinfected with the Group-CHX (15.71 ± 3.04 MPa) bonded with composite showed statistically significantly higher SBS values compared to the laser groups (p < 0.05). No statistically significant difference was noted with specimens disinfected with PDT and Nd:YAG laser showed comparable SBS scores (p > 0.05). Fracture analysis showed equal incidence of adhesive and cohesive failures in control group and Group-CHX. Moreover, a significant number of failures in group-PDT were related to adhesive. Whereas in group 4, admixed type failures were common. CONCLUSION Caries infected hypomineralized teeth demonstrated lower bond strength values compared to non-carious hypomineralized teeth. Adhesive bond strength of hypomineralized teeth was highest with chlorhexidine compared to other laser treatment strategies.

Abstract
PURPOSE The aim of the present clinical trial was to evaluate the efficacy of antimicrobial photodynamic therapy (PDT) for the treatment of halitosis in elderly patients wearing dentures. METHODS Elderly patients (>60 years age) wearing complete dentures and diagnosed with halitosis (H2S levels >112 ppb) were divided into two groups: patients undergoing treatment with tongue scraper and full mouth disinfection (Group I) and patients undergoing treatment with tongue scraper, full mouth disinfection and single application of PDT (Group II). Oral health related quality of life (OHRQoL) was assessed using a 14-point Likert scale used in oral health impact profile (OHIP). The assessment of halitosis was done with the help of a device called Oral Chroma™. Microbial sampling for detection of Porphyromonas gingivalis (P. gingivalis) was performed from the dorsum of the tongue using a sterile swab at baseline and after treatment on day 5, 15 and 30 and quantified using polymerase chain reaction. RESULTS Forty elderly patients with halitosis completed the trial. The mean age in Group I and Group II was estimated to be 66.42 years and 67.91 years, respectively. Group II participants also maintained good OHRQoL in the post-operative period that reported statistically significant difference when compared with the control group (p < 0.01). Group II showed significant improvement in H2S concentration values at final analysis compared to Group-I (p = 0.001). P. gingivalis showed statistically significant reduction on day 5 only with PDT in Group II (p < 0.05). CONCLUSION Antimicrobial PDT helped in reducing H2S gas concentration and improving quality of life in elderly patients wearing dentures. A significant reduction of P. gingivalis occurred only in the short-term follow-up.

Bin-Shuwaish MS. Impact of photodynamic therapy on the push-out bond strength of fiber posts to root dentin: A systematic review and meta-analysis. Photodiagnosis Photodyn Ther 2020; 32:102010. [PMID: 32950727 DOI: 10.1016/j.pdpdt.2020.102010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2020] [Revised: 08/11/2020] [Accepted: 09/08/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND AND PURPOSE This systematic review documents the up-to-date evidence on the efficacy of photodynamic therapy (PDT) on the push-out bond strength of fiber posts cemented to root dentin. MATERIALS AND METHODS The focused PICO question was: "What impact does PDT have on the push-out bond strength of fiber posts cemented to root dentin?" This systematic review followed the guidelines and recommendations reported in the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines chart. An electronic search was performed in MEDLINE/PubMed, SCOPUS, Web of Science, and Embase from January 1980 up to and including January 2020. Heterogeneity was calculated for push-out bond strength by means of the Chi-square test and I2 statistics. For meta-analyses, if the I2 was higher than 50 %, a random effects model was used, otherwise a fixed effects model for I2 ≤50 % was applied. A p-value <0.05 was set for significant heterogeneity. Forest plots were computed reporting standard mean differences (SMD) of outcomes and 95 % confidence intervals (CI). RESULTS In total, ten studies were included, all of wich demonstrated medium risk of bias. All studies tested the push-out bond strength by means of a universal testing machine with applying a load ranging between 0.5 and 1 mm/min speed. Of the 10 studies, nine (90 %) indicated that PDT had no effect on push-out bond strength of fiber posts to root dentin. Only one study indicated that PDT significantly improved the bond strength when compared with other control groups. The overall mean difference for push out bond strength showed no statistically significant difference between PDT and the control group (SMD = -1.11 [-3.25, 1.02], Z=-1.02, p = 0.305). CONCLUSION This systematic review concludes that PDT has no effect on improving the push-out bond strength of fiber posts to root dentin.

Effectiveness of antimicrobial photodynamic therapy in restoring clinical, microbial, proinflammatory cytokines and pain scores in adolescent patients having generalized gingivitis and undergoing fixed orthodontic treatment. Photodiagnosis Photodyn Ther 2020; 32:101998. [PMID: 32916329 DOI: 10.1016/j.pdpdt.2020.101998] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Revised: 08/30/2020] [Accepted: 09/04/2020] [Indexed: 02/08/2023]
Abstract
BACKGROUND The aim of the present study was to evaluate the effectiveness of photodynamic therapy (PDT) on clinical gingival inflammatory parameters, bacterial load, proinflammatory cytokine status, and pain scores in adolescent patients undergoing fixed orthodontic treatment with gingivitis. METHODS Thirty adolescent undergoing fixed orthodontic treatment with gingivitis were randomly divided into two groups: Group A - patients undergoing dental scaling (DS) with adjunctive photodynamic therapy (PDT) and Group BDS alone. Clinical gingival parameters including plaque scores, (PS), bleeding on probing (BOP) and probing depth (PD) were assessed. Visual analogue scale (VAS) and McGill Pain Questionnaire (MPQ) were used to report the values of present pain intensity. Crevicular fluid was sampled to quantify the levels of interleukin (IL)-6 and tumor necrosis factor (TNF)-α using enzyme-linked immunosorbent assay. The total bacterial counts for Porphyromonas gingivalis (P. gingivalis) and Tannerella forsythia (T. forsythia) were assessed. All examinations were performed at baseline, 1 week and 4 weeks. RESULTS Both the treatment regimens reported statistically significant reduction in PS and BOP (p < 0.05). However, no significant difference was observed in PS and PD values when Group B was compared with Group A (p > 0.05). There was a statistically significant reduction noted for BOP in Group B when compared to Group A (p < 0.05). There was a statistically significant reduction in the microbial counts of T. forsythia in Group A when compared to Group B at week-1 (p < 0.05). During the 4-week follow-up, the counts for T. forsythia significantly increased. No significant changes could be seen in either of the pain scores in both the groups (p > 0.05). Both groups showed statistically significant reduction in the IL-6 and TNF-α levels. However, IL-6 was significantly reduced at 1 week, while TNF-a significantly reduced at 4 weeks of follow up among the participants in Group B. CONCLUSION PDT has a positive effect in significantly reducing the periodontal microbial load in established gingivitis in adolescent patients undergoing fixed orthodontic treatment.

Abstract
The aim of this study was to demonstrate the efficacy of 5-aminolevulinic acid photodynamic therapy (ALA-PDT) as an alternative treatment in cutaneous squamous cell carcinoma (cSCC) patients who are not fit for surgery. Thirty-three invasive cSCC patients who, for some reasons, cannot undergo surgery were enrolled in this study. All patients received plum blossom needle (PBN) pretreated ALA-PDT combined with topical application of 5% imiquimod cream. Two patients dropped the study because of severe pain and two patients discontinue treatment due to lack of response. Of 29 patients, who completed the treatment, 5 patients had complete response after 2-9 sessions of PDT and these patients had no recurrence till 18 months after treatment. Twenty-four patients achieved partial response and are satisfied with treatment outcome in terms of decreased symptoms and improved quality of life. PBN pretreated PDT in combination with topical imiquimod may be a viable treatment option for non resectable cSCC lesions.

Abstract
BACKGROUND What impact does tobacco smoking have on photodynamic therapy (PDT) outcome is still unknown. The aim of the present clinical trial was to evaluate the clinical, radiographic, and biological bone markers after provision of PDT in cigarette, e-cigarette, and never-smokers with peri-implantitis (PI) at 6 months post treatment. MATERIALS AND METHODS Twenty-five healthy patients with PI were divided into three groups: Group I: cigarette smokers; Group II: e-cigarettes users; Group III: never-smokers. Full-mouth mechanical debridement with adjunctive methylene blue-mediated PDT was performed. Clinical recordings included peri-implant plaque index (Pi), bleeding on probing (BOP) and probing depth (PD). Peri-implant sulcular fluid was collected for the assessment of biological bone biomarkers including receptor activator of nuclear factor-ligand (RANK-L) and osteoprotegrin (OPG). All assessments were performed at baseline, 3 months and 6 months. P-value of <0.05 was considered significant. RESULTS BOP in Group II and III significantly reduced at 3 months (p < 0.05). Group I showed significant reduction only at 6 months (p < 0.05). Mean PD showed no statistically significant difference between the groups at any time-point. Inter-group comparison showed Group III demonstrating statistically significantly reduced mean RANK-L levels at both 3 and 6 months (p < 0.05). A slight increase in the OPG levels were observed at 3 months and followed by a slight decrease at 6 months for all the study groups when compared with baseline values, however, these values did not show statistical significance (p > 0.05). CONCLUSION Adjunctive PDT helped in reducing the clinical peri-implant inflammation. However, no significant change was observed for biological bone biomarkers among tobacco smokers.

Dent J (Basel) 2020; 8:dj8030068. [PMID: 32635258 PMCID: PMC7560070 DOI: 10.3390/dj8030068] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Revised: 06/29/2020] [Accepted: 07/01/2020] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND The aim of this systematic review is to compare the effectiveness of lasers in the treatment of implant mucositis and peri-implantitis compared to conventional treatment (non-surgical or surgical: resective or regenerative). METHODS Sources of PubMed, Cochrane and Google Scholar search engines were used on articles published from 1997 to 2020 in English, with selected keyword criteria applied. Nine randomized controlled trials (RCTs) were selected. RESULTS All included studies were considered of "high quality" according to the quality assessment scale. The comparative assessment of the RCTs was done twice for each RCT based on the type of treatment and according to wavelength. There is strong scientific evidence that, regarding non-surgical treatment, adjunct laser application can provide better results only in the short term (three months). Regarding the surgical approach, the method of decontamination plays a subordinate role. All wavelengths/applications presented similar results. CONCLUSION Within the limitations of this study, the adjunctive use of lasers in the treatment of peri-implant inflammation is effective for up to three months; there is no strong evidence regarding the long term benefit compared to conventional treatment.
