Is antimicrobial photodynamic therapy an effective treatment for chronic periodontitis in diabetes mellitus and cigarette smokers: a systematic review and meta-analysis

Due to limited evidence, it remains debatable whether aPDT as an adjunct to SRP is effective in improving clinical, microbiological and immunological outcomes compared to SRP alone in T2DM and smokers with CP. Further well-designed, large-scale clinical trials with microbiological parameters and long follow up periods are needed in order to assess the efficacy of adjunctive aPDT in T2DM and cigarette smokers with CP.
