Bahrami R, Pourhajibagher M, Gharibpour F. Antimicrobial photodynamic therapy for the management of gingivitis and white spot lesions in fixed orthodontic patients: A systematic review. Int Orthod 2024; 22:100821. [PMID: 37992475 DOI: 10.1016/j.ortho.2023.100821] [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: 09/06/2023] [Revised: 10/04/2023] [Accepted: 10/13/2023] [Indexed: 11/24/2023]
Abstract
AIM We conducted this review to evaluate the safety and efficacy of antimicrobial photodynamic therapy (aPDT) for the management of gingivitis and white spot lesions (WSLs) in fixed orthodontic patients. METHODS The PubMed/MEDLINE, Cochrane Library, Scopus, and Google Scholar databases were searched for randomized controlled trials and clinical trials assessing the clinical effectiveness of aPDT for the management of gingivitis and WSLs in fixed orthodontic patients without time limitation. Primary outcomes were the changes in clinical parameters such as DIAGNOdent, plaque index (PI), bleeding on probing (BOP), and gingival index (GI). Secondary outcomes included measurements of microbial and inflammatory factors, such as cytokine levels (tumor necrosis factor alpha [TNF-α], interleukin-1 beta [IL-1β], and interleukin-6 [IL-6]), and bacterial counts. RESULTS Our search yielded a total of 12 studies that met the inclusion criteria. Among the 11 studies that evaluated gingivitis, the majority employed a diode laser (670nm, 150 mW, 22J/cm2, 60seconds) as the light source and methylene blue at a concentration of 0.0005% (applied for 3minutes) as the photosensitizer in a single treatment session. The included studies reported positive effects of aPDT on gingivitis management, with more improvements observed in PI, BOP, and GI following aPDT treatment. Additionally, aPDT was found to reduce the counts of periopathogens such as Porphyromonas gingivalis, as well as inflammatory factors (TNF-α, IL-1β, and IL-6). Two studies demonstrated that aPDT, particularly when administered in multiple sessions, effectively controlled the extent of WSLs during orthodontic treatment and yielded favorable outcomes that persisted for several months after treatment. CONCLUSION Based on the available evidence, aPDT appears to be a safe and effective treatment option for managing WSLs and gingivitis in patients with fixed orthodontic appliances. However, further high-quality RCTs are necessary to investigate the impact of potential confounding factors on the efficacy of aPDT.

Novel use of chloro-aluminum phthalocyanine assisted photodynamic therapy helps in periimplant healing among smoking patients. Photodiagnosis Photodyn Ther 2022; 41:103193. [PMID: 36343897 DOI: 10.1016/j.pdpdt.2022.103193] [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: 10/08/2022] [Revised: 11/02/2022] [Accepted: 11/03/2022] [Indexed: 11/06/2022]
Abstract
AIMS To evaluate the clinical and biochemical peri‑implant parameters using chloro‑aluminum phthalocyanine-(CAP) mediated antimicrobial photodynamic therapy (PDT) as an adjunct to non-surgical mechanical debridement (NSD) in cigarette smokers (CS) and never-smokers (NS) with peri‑implantitis. MATERIALS AND METHODS Thirty-two patients with peri‑implantitis [Group CS - 16 and Group NS - 16] were recruited for the trial. The study participants underwent two therapies: PDT + NSD and NSD alone. The clinical peri‑implant parameters assessed in this clinical trial were bleeding on probing (BP), crestal bone loss (CBL) peri‑implant pocket depth (PD), and peri‑implant plaque scores (PS), respectively. Peri-implant crevicular fluid was sampled and the quantification of interleukin (IL)-1β and tumor necrosis factor-alpha (TNF-α) was performed using enzyme linked immunosorbent assay (ELISA). RESULTS BP was significantly reduced at 6 months after PDT+NSD in CS groups. Mean PD significantly reduced after both PDT+NSD and NSD subgroups within both NS and CS groups. Only at 6 months did PDT+NSD showed statistically significantly reduced IL-1β levels in the NS group. TNF-α levels significantly reduced in CS group with PDT+NSD and NSD alone at both 3 months and 6 months follow up. CONCLUSION CAP-assisted PDT helped to improve the clinical and cytokine levels after non-surgical peri‑implant mechanical debridement in treating peri‑implantitis patients in smokers.

Abstract
The emergence of drug-resistant bacteria is considered a critical public health problem. The need to establish alternative approaches to countering resistant microorganisms is unquestionable in overcoming this problem. Among emerging alternatives, antimicrobial photodynamic therapy (aPDT) has become promising to control infectious diseases. aPDT is based on the activation of a photosensitizer (PS) by a particular wavelength of light followed by generation of the reactive oxygen. These interactions result in the production of reactive oxygen species, which are lethal to bacteria. Several types of research have shown that aPDT has been successfully studied in in vitro, in vivo, and randomized clinical trials (RCT). Considering the lack of reviews of RCTs studies with aPDT applied in bacteria in the literature, we performed a systematic review of aPDT randomized clinical trials for the treatment of bacteria-related diseases. According to the literature published from 2008 to 2022, the RCT study of aPDT was mostly performed for periodontal disease, followed by halitosis, dental infection, peri-implantitis, oral decontamination, and skin ulcers. A variety of PSs, light sources, and protocols were efficiently used, and the treatment did not cause any side effects for the individuals.

Abstract
PURPOSE To evaluate the efficacy of photodynamic therapy (PDT) as an adjunct to non-surgical periodontal therapy on the clinical periodontal and biochemical parameters among patients with rheumatoid arthritis (RA) having periodontitis. METHODS A total of 50 RA patients with periodontitis were included. The subjects were equally divided into two groups: Group A - scaling and root planning (SRP) + PDT; Group B - SRP only, respectively. Plaque score (PS), bleeding on probing (BOP), and pocket depth (PD) were estimated. The biochemical parameters included the assessment of interleukin 6 (IL-6), tumor necrosis factor-alpha (TNF-α) and rheumatoid factors (RFs). RESULTS Plaque scores and BOP significantly reduced in both the groups at both 6 and 12 weeks with significant difference between both the groups at 6 weeks follow up (p<0.05). On inter-group comparison, there was a statistically significant reduction seen for BOP in Group A at 12 weeks (p<0.001). PD significantly reduced in both the groups at both time points; however, significant reduction was noted for Group A compared to Group B (p<0.01). IL-6 and TNF-α significantly reduced in both the groups at 6 and 12 weeks follow up. However, the proinflammatory cytokine levels significantly reduced in group A as compared to group B at both 6 and 12 weeks (p<0.05). GCF levels of RF did not show any change in either of the groups at either time point or between the groups (p>0.05). CONCLUSION PDT significantly reduced the proinflammatory burden in terms of periodontal attachment level and bleeding on probing within the periodontal inflammatory pockets in patients having RA.

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.

Abstract
Treatment of malocclusions using fixed orthodontic appliances makes it difficult for patients to perform hygiene procedures. Insufficient removal of bacterial biofilm can cause enamel demineralization, manifesting by visible white spot lesions or periodontal diseases, such as gingivitis periodontitis or gingival hyperplasia. The classic methods of preventing the above problems include, in addition to proper hygiene, ultrasonic scaling, periodontal debridement, and oral rinses based on chlorhexidine. New alternative methods of reducing plaque around brackets are being developed. There is a growing interest among researchers in the possibility of using photodynamic therapy in orthodontics. A literature search for articles corresponding to the topic of this review was performed using the PubMed and Scopus databases and the following keywords: ‘photodynamic therapy’, ‘orthodontics’, and ‘photosensitizer(s)’. Based on the literature review, two main directions of research can be distinguished: clinical research on the use of photodynamic therapy in the prevention of white spot lesions and periodontal diseases, and ex vivo research using a modified orthodontic adhesive by adding photosensitizers to them. Methylene blue is the most frequently used photosensitizer in clinical trials. The effectiveness of antimicrobial photodynamic therapy is mainly compared to the ultrasonic scaler as a single therapy or as an adjunct to the ultrasonic scaler. In their conclusions, the researchers most often emphasize the effectiveness of antimicrobial photodynamic therapy in reducing microbial levels in patients treated with fixed appliances and the possibility of using it as an alternative to routine procedures aimed at maintaining a healthy periodontium. The authors suggest further research on the use of photodynamic therapy to prove the validity of this method in orthodontics. It should also not be forgotten that proper hygiene is the basis for maintaining oral cavity health, and its neglect is a contraindication to orthodontic treatment.

The effect of antimicrobial photodynamic therapy on shear bond strength of orthodontic bracket: An in vitro study. Photodiagnosis Photodyn Ther 2021; 34:102244. [PMID: 33677068 DOI: 10.1016/j.pdpdt.2021.102244] [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: 12/08/2020] [Revised: 02/23/2021] [Accepted: 03/01/2021] [Indexed: 12/17/2022]
Abstract
OBJECTIVES The aim of this study was to evaluate the effect of antimicrobial photodynamic therapy (aPDT) with methylene blue (MB) and indocyanine green (ICG) on bond strength of orthodontic brackets to enamel. MATERIALS AND METHODS A total of 45 non-carious and sound human premolar teeth were used in this study. All teeth were examined under a stereomicroscope at ×10 magnification. The samples were divided to 3 groups including no treatment (control group), aPDT with MB and 660 nm diode laser and aPDT with ICG and 808 nm diode laser. After aPDT procedure, orthodontic brackets were bonded to enamel surfaces. Then, the samples were thermocycled for 5000 cycles between 5° and 55° C in water bath. The brackets were then debonded using a universal testing machine. The adhesive remnant index (ARI) score and SEM microscope evaluation were assessed. One-way analysis of variance (ANOVA) with Post-hoc test were used to compare the SBS values among groups. RESULTS The highest SBS mean value was presented in group 1 (control) (31.98 ± 6.36). Whereas, the lowest SBS mean value was observed in group 3 (aPDT with ICG) (24.11 ± 5.78). There were significant differences in SBS values between control and aPDT groups (P < 0.05). Some superficial porosity and irregularity was presented following aPDT on surface of enamel when examined by scanning electron microscope. The mode of failure was mostly score 0 and score 1 in all groups. CONCLUSION MB and ICG mediated antimicrobial photodynamic therapy both reduced the bond strength of orthodontic brackets compared to control group.

Effectiveness of Riboflavin and Rose Bengal Photosensitizer Modified Adhesive Resin for Orthodontic Bonding. Pharmaceuticals (Basel) 2021; 14:ph14010048. [PMID: 33435179 PMCID: PMC7826870 DOI: 10.3390/ph14010048] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2020] [Revised: 12/30/2020] [Accepted: 01/01/2021] [Indexed: 02/06/2023] Open
Abstract
This study aimed to evaluate the effect of riboflavin (RF) and Rose Bengal (RB) photosensitizer modified adhesive resin on the degree of conversion (DC), and antimicrobial capacity after bonded to tooth surface. Different concentrations of RB and RF were prepared by homogenization method. An ultraviolet light source A (UVA) (375 nm wavelength, 3 mW/cm2 power) was used for 30 min irradiation. FTIR was performed for control and test adhesives to analyze the DC. Antibacterial testing was performed using the MTT assay. Metal brackets were bonded using the modified adhesives and subjected for SEM examination. The surfaces of teeth and metal brackets were examined at ×10 magnification for assessing adhesive remnant index (ARI) after PDT, 24 h and thermocycling. For DC, control group, 0.1% RB and RF after PDT showed the highest value. SEM imaging indicated lowest growth of Streptococcus mutans over 0.5% of RB-PDT and RF-PDT as compared to the control group. The MTT assay outcomes reported that the activity of S. mutans substantially decreased with the addition of a high amount of either RB or RF (p < 0.01). Mean ARI scores showed a significant difference between all groups. This study concluded that 0.1% of either RB or RF after PDT can be used for bonding orthodontic brackets to the tooth surface with substantial antibacterial properties.
