Background: This pilot study aimed to evaluate the effect of antimicrobial photodynamic therapy (aPDT) as an adjuvant to non-surgical periodontal therapy (NSPT) on periodontal status and glycemic control in patients with type 2 diabetes mellitus and generalized chronic periodontitis. Methods: Twelve patients were evaluated at five time points: during the preparation of the patient (T0), during the treatment phase (T1) and after 30 (T2), 90 (T3) and 180 (T4) days. The patients had a mean age of 52.2 years and a 9.58-year history of diabetes, on average, and were divided into two randomized treatment groups: 6 patients received NSPT combined with aPDT (G1) and 6 patients received only NSPT (G2). The aPDT was applied associating the photosensitizing agent methylene blue (10 mg/ ml) with a red laser (660 nm–40 mW). The total time of exposure was 2 min per tooth.Results: Whitin the limitation of this study, the results showed that the plaque index reduced significantly only in the control group (p = 0.02) at T2 (30 days). For bleeding on probing, both groups showed a significant re duction between T1 and T2, with no difference between groups G1 and G2. Regarding the probing depth, there were no differences between groups, but the parameters decreased over time when compared to T1. The glycated
haemoglobin and fructosamine levels did not significantly differ between or within the groups at any time point. Conclusion: When NSPT was combined with aPDT, no additional benefits were observed for the periodontal and metabolic clinical parameters
