Background: Antimicrobial photodynamic therapy (aPDT) has been proposed as an effective alternative method for the adjunctive treatment of all classes of oral infections. The multifactorial nature of its mechanism of action correlates with various influencing factors, involving parameters concerning both the photosensitizer and the light delivery system. This study aims to critically evaluate the recorded parameters of aPDT applications that use lasers as the light source in randomized clinical trials in dentistry. Methods: PubMed and Cochrane search engines were used to identify human clinical trials of aPDT therapy in dentistry. After applying specific keywords, additional filters, inclusion and exclusion criteria, the initial number of 7744 articles was reduced to 38. Results: Almost one-half of the articles presented incomplete parameters, whilst the others had different protocols, even with the same photosensitizer and for the same field of application. Conclusions: No safe recommendation for aPDT protocols can be extrapolated for clinical use. Further research investigations should be performed with clear protocols, so that standardization for their potential dental applications can be achieved.

“…Of the initial searches, 7 studies were retained for further investigation and 3 articles were excluded primarily based on their lack of appropriate endpoints matching our search criteria [34][35][36] . Finally, 4 randomized controlled trials were initially identi ed carefully from the proposed electronic databases, of which one study was omitted due to dual intervention (aPDT + NYT) in comparison with NYT 37 . Hence, based on the eligibility criteria, 3 RCTs were considered for qualitative and quantitative analysis 20,27,28 (Fig.…”
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-Analysis (PRISMA) updated guidelines. A literature search was performed in four electronic databases to identify relevant articles up to 15 August 2021. Randomized 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 3 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 patientsâ palate and patientsâ 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 standardized methodology should be conducted to validate this conclusion.
“…Afroozi et al 44 also aimed to compare conventional nystatin therapy with PDT, enrolling 66 patients. The control group was treated with oral nystatin drop.…”
Background
The introduction of photodynamic therapy (PDT) in various branches of the dental field such as endodontics, implantology, periodontology, and restorative dentistry and oral medicine has become useful in recent decades. This systematic review presents an overview of the literature to evaluate the usefulness of topical PDT for the treatment of benign oral soft tissue lesions and to identify limitations in prior studies to improve PDT applications.
Methods
We performed a review of the literature using different search engines (PubMed, ISI Web of Science, and the Cochrane Library) employing MeSH terms such as "Photodynamic therapy" and "PDT" in conjunction with other terms. We utilized the Population, Intervention, Comparison, Outcomes, and Study design (PICOS) method to define our study eligibility criteria.
Results
Initial results were 1513. Finally, there were only 21 studies that met our selection criteria. We divided the 21 selected items into two groups: inflammatory diseases and infective diseases.
Conclusions
Although topical PDT is an easy to perform and wellâtolerated treatment and appears to be a valid method with promising results in the treatment of benign lesions of the oral cavity's soft tissues, further studies are needed to complete the current knowledge of this technique.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citationsâcitations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
