Abstract: Objective: To explore the therapeutic effect of photodynamic therapy (PDT) on patients with type II diabetes mellitus and chronic periodontitis. Methods: Forty-eight patients with chronic periodontitis were randomly divided into PDT group (n=24) and control group (n=24) with and without PDT after supragingival scaling, and scaling and root planning (SRP). Levels of fasting blood glucose (FGP) and glycosylated hemoglobin (HbAle), and periodontal status were examined as well as matrix metalloproteinase-8 (MMP-8) and interleukin-1 (IL-1).Results: The total effective rate of PDT group was 91.67%, which was significantly higher than the control group (P<0.05). Three months after treatment, the level of HbAle in PDT group was significantly lower than that of one week after supragingival scaling without PDT and the control group (P<0.05). PD, AL, BI, and PLI were significantly decreased in the two groups after 6 weeks and 3 months after treatment. Compared with the control group, the PDT group was significantly decreased (P<0.05). The level of MMP-8 and IL-1 were significantly decreased in two groups after treatment (P<0.05), while the PDT group decreased more significantly (P<0.05).Conclusion: PDT can effectively improve periodontitis patients with type II diabetes, and reduce the level of inflammation reaction.
