| Summary: | Abstract Objectives This systematic review evaluated the evidence for the effectiveness of Photodynamic therapy (PDT) in treating oral fungal infections, as an alternative to conventional antifungal medications. Methods Five randomized control trials (168 participants) comparing the treatment of oral fungal infections using met with our inclusion criteria. Clinical and microbiological improvement was assessed by random‐effects meta‐analysis. Methodological quality assessment and heterogeneity were performed using peer‐reviewed criteria. PROSPERO registration: CRD42017076. Results PDT showed statistically non‐significant increased clinical efficacy (risk ratio (RR) = 1.47 [95% confidence interval (CI), 0.68; 3.17]; three studies, n = 108 participants, I2 = 50%) and mycological efficacy (mean difference (MD) = 0.54 [95%CI, −0.71; 1.79]; three studies, n = 100; I2 = 39%) at 30 days, as compared with conventional antifungal therapy. Lack of standardization of treatment parameters and variability in the assessment of outcomes was observed across the studies. All included studies had a moderate to low risk of bias. Conclusions PDT showed comparable effectiveness at treating oral fungal infections, particularly denture stomatitis. The small number of studies in this review, small sample size and variability of methods and outcome measures across studies, highlight the need for more standardized studies with longer follow‐up periods to enable recommendation of PDT as an alternative to conventional antifungal therapy.
