Abstract
BACKGROUND Periodontitis and peri-implant diseases are chronic inflammatory conditions occurring in the mouth. Left untreated, periodontitis progressively destroys the tooth-supporting apparatus. Peri-implant diseases occur in tissues around dental implants and are characterised by inflammation in the peri-implant mucosa and subsequent progressive loss of supporting bone. Treatment aims to clean the pockets around teeth or dental implants and prevent damage to surrounding soft tissue and bone, including improvement of oral hygiene, risk factor control (e.g. encouraging cessation of smoking) and surgical interventions. The key aspect of standard non-surgical treatment is the removal of the subgingival biofilm using subgingival instrumentation (SI) (also called scaling and root planing). Antimicrobial photodynamic therapy (aPDT) can be used an adjunctive treatment to SI. It uses light energy to kill micro-organisms that have been treated with a light-absorbing photosensitising agent immediately prior to aPDT. OBJECTIVES To assess the effects of SI with adjunctive aPDT versus SI alone or with placebo aPDT for periodontitis and peri-implant diseases in adults. SEARCH METHODS We searched the Cochrane Oral Health Trials Register, CENTRAL, MEDLINE, Embase, two other databases and two trials registers up to 14 February 2024. SELECTION CRITERIA We included randomised controlled trials (RCTs) (both parallel-group and split-mouth design) in participants with a clinical diagnosis of periodontitis, peri-implantitis or peri-implant disease. We compared the adjunctive use of antimicrobial photodynamic therapy (aPDT), in which aPDT was given after subgingival or submucosal instrumentation (SI), versus SI alone or a combination of SI and a placebo aPDT given during the active or supportive phase of therapy. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodological procedures, and we used GRADE to assess the certainty of the evidence. We prioritised six outcomes and the measure of change from baseline to six months after treatment: probing pocket depth (PPD), bleeding on probing (BOP), clinical attachment level (CAL), gingival recession (REC), pocket closure and adverse effects related to aPDT. We were also interested in change in bone level (for participants with peri-implantitis), and participant satisfaction and quality of life. MAIN RESULTS We included 50 RCTs with 1407 participants. Most studies used a split-mouth study design; only 18 studies used a parallel-group design. Studies were small, ranging from 10 participants to 88. Adjunctive aPDT was given in a single session in 39 studies, in multiple sessions (between two and four sessions) in 11 studies, and one study included both single and multiple sessions. SI was given using hand or power-driven instrumentation (or both), and was carried out prior to adjunctive aPDT. Five studies used placebo aPDT in the control group and we combined these in meta-analyses with studies in which SI alone was used. All studies included high or unclear risks of bias, such as selection bias or performance bias of personnel (when SI was carried out by an operator aware of group allocation). We downgraded the certainty of all the evidence owing to these risks of bias, as well as for unexplained statistical inconsistency in the pooled effect estimates or for imprecision when evidence was derived from very few participants and confidence intervals (CI) indicated possible benefit to both intervention and control groups. Adjunctive aPDT versus SI alone during active treatment of periodontitis (44 studies) We are very uncertain whether adjunctive aPDT during active treatment of periodontitis leads to improvement in any clinical outcomes at six months when compared to SI alone: PPD (mean difference (MD) 0.52 mm, 95% CI 0.31 to 0.74; 15 studies, 452 participants), BOP (MD 5.72%, 95% CI 1.62 to 9.81; 5 studies, 171 studies), CAL (MD 0.44 mm, 95% CI 0.24 to 0.64; 13 studies, 414 participants) and REC (MD 0.00, 95% CI -0.16 to 0.16; 4 studies, 95 participants); very low-certainty evidence. Any apparent differences between adjunctive aPDT and SI alone were not judged to be clinically important. Twenty-four studies (639 participants) observed no adverse effects related to aPDT (moderate-certainty evidence). No studies reported pocket closure at six months, participant satisfaction or quality of life. Adjunctive aPDT versus SI alone during supportive treatment of periodontitis (six studies) We were very uncertain whether adjunctive aPDT during supportive treatment of periodontitis leads to improvement in any clinical outcomes at six months when compared to SI alone: PPD (MD -0.04 mm, 95% CI -0.19 to 0.10; 3 studies, 125 participants), BOP (MD 4.98%, 95% CI -2.51 to 12.46; 3 studies, 127 participants), CAL (MD 0.07 mm, 95% CI -0.26 to 0.40; 2 studies, 85 participants) and REC (MD -0.20 mm, 95% CI -0.48 to 0.08; 1 study, 24 participants); very low-certainty evidence. These findings were all imprecise and included no clinically important benefits for aPDT. Three studies (134 participants) reported adverse effects: a single participant developed an abscess, though it is not evident whether this was related to aPDT, and two studies observed no adverse effects related to aPDT (moderate-certainty evidence). No studies reported pocket closure at six months, participant satisfaction or quality of life. AUTHORS' CONCLUSIONS Because the certainty of the evidence is very low, we cannot be sure if adjunctive aPDT leads to improved clinical outcomes during the active or supportive treatment of periodontitis; moreover, results suggest that any improvements may be too small to be clinically important. The certainty of this evidence can only be increased by the inclusion of large, well-conducted RCTs that are appropriately analysed to account for change in outcome over time or within-participant split-mouth study designs (or both). We found no studies including people with peri-implantitis, and only one study including people with peri-implant mucositis, but this very small study reported no data at six months, warranting more evidence for adjunctive aPDT in this population group.

Alasqah MN. Efficacy of methylene blue-mediated antimicrobial photodynamic therapy on clinical and radiographic outcomes among patients with periodontal diseases: A systematic review and meta-analysis of randomized controlled trials. Photodiagnosis Photodyn Ther 2024; 46:104000. [PMID: 38316339 DOI: 10.1016/j.pdpdt.2024.104000] [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: 11/13/2023] [Revised: 01/30/2024] [Accepted: 02/02/2024] [Indexed: 02/07/2024]
Abstract
OBJECTIVE This study aimed to assess the influence of methylene blue (MB)-mediated adjunctive antimicrobial photodynamic therapy (aPDT) when compared to conventional mechanical debridement (MD) alone on periodontal clinical and radiographic outcomes among periodontitis patients. METHODS Randomized clinical trials (RCTs) were incorporated by conducting an electronic search in Web of Science, Scopus, and PubMed for articles published in English up to August 2023 to address the following focused question based on the PICO format: "Whether the application of MB-mediated aPDT as an adjunctive to MD (Intervention) leads to improved periodontal clinical and/or radiographic outcomes (Outcome) among participants with and without periodontal diseases (Population) as compared to MD alone (Conparison)". The risk of bias (RoB) of the included studies was assessed using the modified Jadad scale. A meta-analysis was conducted, and it included the presentation of the standard mean difference (SMD) along with a 95 % confidence interval (CI). RESULTS In total, 11 studies were included in this systematic review and meta-analysis. The meta-analysis demonstrated statistically significant improvements in periodontal plaque index (SMD: -0.72 % [95 % CI: -0.99 % to -0.45 %]; p<0.00001), probing depth (SMD: -0.38 % [95 % CI: -0.57 % to -0.19 %; p<0.00001), and bleeding on probing (SMD: -0.44 % [95 % CI: -0.68 % to -0.20 %]; p = 0.0003) scores at the final follow-up visit after the application of MB-mediated aPDT in comparison with MD alone. Nevertheless, there was no statistically significant difference was observed in periodontal clinical attachment level values (SMD: -0.01 % [95 % CI: -0.21 % to 0.19 %]; p = 0.95) between the control group and the experimental group. Six studies achieved a low RoB, five were rated as having medium RoB, while no study received a high RoB. CONCLUSION MB-mediated aPDT, when used as an adjunct to conventional MD contributes to the improvement of periodontal clinical outcomes including PI, PD, and BOP in patients with periodontitis.

Abstract
BACKGROUND Periodontal diseases (PDs) have been documented to be significantly more prevalent and severe in patients with Down syndrome (DS). Different immunological and microbiological factors contributed to predisposing these patients to progressive and recurrent PDs. AIM The aim of this review was to investigate the altered immunological responses and oral microbiota disorders as well as focus on adjunctive non-surgical methods for the treatment of PDs and its applicability in patients with DS. MATERIAL AND METHODS A literature review was conducted addressing the following topics: (1) the altered immunological responses, (2) orofacial disorders related to DS patients, (3) oral microbiota changing, and (4) adjunctive non-surgical treatment and its efficacy in patients with DS. RESULTS Due to the early onset of PDs in children with DS, the need for prompt and effective treatment in these patients is essential. DISCUSSION AND CONCLUSION So, investigating underlying factors may open a new window to better understand the pathology of PDs in DS people and thus, find better strategies for treatment in such group. Although non-surgical treatments such as photodynamic therapy and probiotic consumption represented acceptable outcomes in different examined patients without DS, data about the application of these convenience and no need for local anesthesia methods in patients with DS is limited.

[PMID: 36841175 DOI: 10.1016/j.jphotobiol.2023.112670] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 01/22/2023] [Accepted: 02/13/2023] [Indexed: 02/16/2023]
Abstract
BACKGROUND Antimicrobial blue light (aBL) kills a variety of bacteria, including Porphyromonas gingivalis. However, little is known about the transcriptomic response of P. gingivalis to aBL therapy. This study was designed to evaluate the selective cytotoxicity of aBL against P. gingivalis over human cells and to further investigate the genetic response of P. gingivalis to aBL at the transcriptome level. METHODS Colony forming unit (CFU) testing, confocal laser scanning microscopy (CLSM), and scanning electron microscopy (SEM) were used to investigate the antimicrobial effectiveness of blue light against P. gingivalis. The temperatures of the irradiated targets were measured to prevent overheating. Multiple fluorescent probes were used to quantify reactive oxygen species (ROS) generation after blue-light irradiation. RNA sequencing (RNA-seq) was used to investigate the changes in global gene expression. Following the screening of target genes, real-time quantitative polymerase chain reaction (RT-qPCR) was performed to confirm the regulation of gene expression. RESULTS A 405 nm aBL at 100 mW/cm2 significantly killed P. gingivalis within 5 min while sparing human gingival fibroblasts (HGFs). No obvious temperature changes were detected in the irradiated surface under our experimental conditions. RNA-seq showed that the transcription of multiple genes was regulated, and RT-qPCR revealed that the expression levels of the genes RgpA and RgpB, which may promote heme uptake, as well as the genes Ftn and FetB, which are related to iron homeostasis, were significantly upregulated. The expression levels of the FeoB-2 and HmuR genes, which are related to hydroxyl radical scavenging, were significantly downregulated. CONCLUSIONS aBL strengthens the heme uptake and iron export gene pathways while reducing the ROS scavenging pathways in P. gingivalis, thus improving the accumulation of endogenous photosensitizers and enhancing oxidative damage to P. gingivalis.

Short-term influence of antimicrobial photodynamic therapy as an adjuvant to mechanical debridement in reducing soft-tissue inflammation and subgingival yeasts colonization in patients with peri-implant mucositis. Photodiagnosis Photodyn Ther 2023; 42:103320. [PMID: 36737030 DOI: 10.1016/j.pdpdt.2023.103320] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Revised: 01/13/2023] [Accepted: 01/31/2023] [Indexed: 02/04/2023]
Abstract
OBJECTIVE The objective of this short-term follow-up study was to evaluate the influence of antimicrobial photodynamic therapy (aPDT) as an adjuvant to mechanical debridement (MD) in reducing soft-tissue inflammation and subgingival yeasts colonization (SYC) in patients with peri‑implant mucositis (PiM). METHODS Individuals diagnosed with PiM were included. Demographic data was collected using a questionnaire. Peri-implant plaque index (PI), bleeding index (BI), probing depth (PD), crestal bone levels and SYC were measured at baseline. Therapeutically, these individuals were divided into test and control groups. In the control-group patients underwent MD and in the test-group patients underwent MD with adjunct single session of aPDT. Clinical peri‑implant parameters and SYC were reassessed after 12-weeks. Correlation between age, gender and duration of implants with SYC and clinical peri‑implant status was assessed using logistic regression models. P < 0.05 was selected as an indicator of statistical significance. RESULTS The test and control-groups comprised of 24 and 23 individuals, respectively. In the test and control groups, toothbrushing twice daily was reported by 7 (29.2%) and 5 (21.7%) individuals, respectively. None of the individuals had ever used a dental floss. At baseline, there was no difference in peri‑implant PI, BI, PD and CBL in the test and control groups. At follow-up, peri‑implant PI (P < 0.01), BI (P < 0.01) and PD (P < 0.01) were significantly higher in the control compared with the test-group. At baseline, SYC in the test and control groups were 1865.3 ± 403.4 CFU/ml and 1963.7 ± 512.4 CFU/ml, respectively. At 90 days' follow-up, SYC in the test and control groups were 1472 ± 202.7 and 1538.4 ± 331.7 CFU/ml, respectively. There was no significant difference in SYC in both groups when baseline values were compared with 90 days' follow-up. CONCLUSION One session of aPDT after MC with adjunct aPDT is effective in reducing soft tissue inflammation but not SYC in patients with PiM.

Abstract
Aim: to evaluate the adjunctive effects of photodynamic therapy (aPDT) on nonsurgical mechanical treatment in patients with periodontitis. Materials and methods: The search strategy was conducted according to the PRISMA guidelines to answer research questions regarding the effectiveness of aPDT in association with non-surgical periodontal therapy. The mean values and standard deviations were collected by data extraction. A descriptive comparison between aPDT in association with periodontal treatment and periodontal treatment alone was performed, and meta-analyses of PPD were also performed. Both randomized controlled clinical trials (RCTs) and controlled clinical trials (CCTs) were included. Results: Out of 2059 records, 14 articles on adjunctive photodynamic therapy were included because they met the eligibility criteria. A comparison between the aPDT data and the control group showed improved PPD for photodynamic therapy (SMD −0.76, p = 0.003; I2 = 88%). Statistical analysis was then applied to the three PPD subgroups. The first group included studies that used indocyanine green in association with a wavelength of 810 nm (SMD −1.79, p < 0.00001, I2 = 88%). The second group included studies that used phenothiazine chloride at a wavelength of 660 nm (SMD −0.03, p = 0.84, I2 = 0%). The last group included studies that used methylene blue photosensitizers treated with a wavelength 628–670 nm were included (SMD −0.13, p = 0.38; I2 = 0%). Conclusions: despite the limited number of RCTs and the great heterogeneity between them, it can be concluded that aPDT in association with nonsurgical periodontal treatment improved the clinical parameters at 3 months.

Abstract
Considering the current context of the increasing resistance of bacterial species to antibiotics and other antimicrobial agents, a major objective is to develop other antimicrobial approaches, which would be able to inactivate pathogens with considerable effectiveness. Two such methods are photodynamic disinfection therapy and laser irradiation. In view of the immunocompromised status of some patients under immunosuppressive therapy and potential drug interactions that can be established between systemic antimicrobial agents, the research of local, minimally invasive methods of inactivating periodontal pathogens in the context of these systemic therapies with modifying drugs of the immune response is justified. This in vitro study evaluated the antimicrobial action of a diode laser, wavelength 940 nm, and photodisinfection therapy at 670 nm (photosensitizer, 3,7 dimethyl phenothiazine chloride) on a type strain of Aggregatibacter actinomycetemcomitans, a known periodontal pathogen, in the presence and absence of active substances used in autoimmune disease therapy (Etanercept, Infliximab, Metothrexate). The association of a conventional antirheumatic drug with anti-TNF-α therapy determined a significantly greater inhibition of the strain of A. actinomycetemcomitans compared to monotherapy, in vitro. Photodisinfection caused a significant reduction in bacterial burden after a 30 s exposure in vitro, regardless of the pharmaceutical associations of biological and conventional disease-modifying antirheumatic drugs (DMARDs). Irradiation with a diode laser for 30 s at a power of 5 W caused a greater reduction compared to irradiation with 1 W. The application of laser and photodisinfection induced a significant reduction in Aggregatibacter actinomycetemcomitans in vitro and could be considered important adjunctive measures for the eradication of this oral pathogen in the context of immunomodulating therapy.

Abstract
INTRODUCTION The aim of the present randomized controlled trial was to assess the effect of mechanical instrumentation (MI) with adjunct photodynamic therapy (PDT) on salivary tumor necrosis factor-alpha (TNFα) levels and clinical periodontal and peri‑implant status in patients with depression. MATERIALS AND METHODS In groups 1 and 2, individuals with periodontal and peri‑implant diseases with and without depression, respectively were included. Group-3 comprised of systemically healthy individuals with a healthy periodontal and peri‑implant status. In groups 1 and 2, patients in the test- and control groups received MI with and without PDT respectively. Periodontal and peri‑implant probing depth and plaque and gingival indices were measured. Radiographic evaluation was done at baseline. Whole salivary tumor necrosis factor alpha (TNFα) in peri‑implant sulcular fluid were measured at baseline. The clinical and immunological parameters were reassessed at 120 days' follow-up. Level of significance was set at P<0.05. RESULTS Thirty-four, 36 and 37 implants were in function in groups 1, 2 and 3, respectively. At baseline, periodontal and peri‑implant clinical parameters and TNFα levels were significantly higher in groups 1 (P<0.05) and 2 (P<0.05) than Group-3. At 4-months follow-up, there was no difference in periodontal and peri‑implant clinical parameters in the test- and control groups among individuals in groups 1 and 3. In Group-2, there was a significant reduction in periodontal (P<0.05) and peri‑implant (P<0.05) clinical parameters at 4-months follow-up than baseline. In Group-2, there was no significant difference in these parameters among patients in the test- and control-groups. CONCLUSION In patients with depression clinical periodontal and peri‑implant status is poorer and salivary TNFα levels are higher after MI with or without PDT. In healthy patients, PDT offers no additional benefits in the treatment of periodontal inflammation.

Periodontal status and whole salivary adipokines after scaling and root planing with and without adjunct antimicrobial photodynamic therapy in obese patients with periodontitis. Photodiagnosis Photodyn Ther 2022; 40:103112. [PMID: 36089266 DOI: 10.1016/j.pdpdt.2022.103112] [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: 08/23/2022] [Revised: 08/26/2022] [Accepted: 09/06/2022] [Indexed: 12/14/2022]
Abstract
OBJECTIVE Whole-salivary (WS) adiponectin and leptin levels after scaling and root planing (SRP) with and without antimicrobial-photodynamic-therapy (aPDT) in obese and normal-weight individuals with periodontitis remain uninvestigated. This study compared the effect of SRP without and with adjuvant aPDT on periodontal status and WS leptin and adiponectin levels (LAL) in obese patients with periodontitis. METHODS Groups 1 and 2 entailed obese patients without and with periodontitis. Groups 3 and 4 had normal weight individuals without and with periodontitis. Therapeutically, individuals with periodontitis were categorized into test- (SRP+aPDT) and control- (SRP alone) subgroups. All patients without periodontitis underwent routine dental prophylaxis. Clinical attachment loss (AL), gingival and plaque index (GI and PI), probing depth (PD), missing teeth (MT) and WS LAL were measured at baseline and at three months of follow-up. P<5% were graded statistically significant. RESULTS At baseline, clinicoradiographic variables were significantly higher among patients in test- and control-groups in groups 1 (P<0.01) and 3 (P<0.01) versus 2 and 4. In group 2 and 3, LL were significantly high at baseline compared with follow-up (P<0.01). There was no difference in periodontal parameters and WS adiponectin and LL in the test and control-groups at of follow-up. No correlation existed between salivary LAL and clinical periodontal parameters (PI, GI, PD and clinical AL). No correlation existed between age, gender and BMI and WS LAL. CONCLUSION In the short-term, SRP with or without aPDT is ineffective in the treatment of periodontitis in obese patients with periodontitis.

Abstract
The aim was to compare the in-vitro antibacterial effectiveness of two herbal extracts (a) Saussurea-costus (S. costus) and (b) Melaleuca-alternifolia (M. alternifolia) against Porphyromonas gingivalis (P. gingivalis), Streptococcus mutans (S. mutans) and Enterococcus faecalis (E. faecalis). Aqueous extracts from M. alternifolia were prepared by adding 2 grams of S. costus and M. alternifolia, respectively to 100 ml distilled water. Bacterial strains of P. gingivalis, E. faecalis and S. mutans were treated into 3 groups. In groups 1 and 2, bacterial strains were treated with aqueous extracts of S. costus and M. alternifolia, respectively. In the control-group, bacterial strains were exposed to distilled water. Antibacterial activity of the samples and nanoparticles was determined. The minimum-inhibitory-concentration (MIC) values were determined using the microdilution method. P < 0.01 was considered statistically significant. The MIC for all bacterial strains treated with S. costus was significantly higher than that of M. alternifolia (P < 0.001). There was no significant difference in MIC for strains of P. gingivalis, E. faecalis and S. mutans treated with S. costus. For bacterial strains treated with M. alternifolia, the MIC was significantly higher for P. gingivalis compared with E. faecalis and S. mutans strains (P < 0.01). There was no difference in MIC for E. faecalis and S. mutans strains treated with M. alternifolia. The in-vitro antibacterial efficacy of M. alternifolia is higher than S. costus against P. gingivalis, E. faecalis and S. mutans.
