Effect of the antimicrobial photodynamic therapy in the treatment of periodontitis in type 2 diabetes mellitus: a systematic review and meta-analysis

Abstract

Objective This systematic review and meta-analysis was undertaken to evaluate the efficacy of antibacterial photodynamic therapy (aPDT) in the treatment of periodontitis in type-2 diabetes mellitus (T2DM) patients and to provide better treatment for patients with T2DM complicated with periodontitis.Methods The PubMed, Cochrane, Embase, Web of Science, CNKI, CBM, and Wanfang databases were searched for relevant randomized controlled trials (RCTs). RevMan 5.3 was applied for the meta-analysis, and a systematic evaluation was conducted. Results A total of 8 RCTs were included. The results showed that compared to simple subgingival scaling and root planing (SRP), aPDT assisted SRP had a better effect on improving the probing depth (PD) at 3 months after treatment, The difference was statistically significant [WMD=-0.32,95%CI（-0.45, -0.2）, P 0.05).Conclusion aPDT-assisted periodontal nonsurgical treatment in T2DM patients can improve PD in the short term but has no significant effect on the improvement of CAL, BOP and HbA1c.
