Role of Probiotics for the Treatment of Peri-Implant Mucositis in Patients With and Without Type 2 Diabetes Mellitus.

Abstract

This study hypothesized that probiotic therapy (PT) does not offer additional benefits to mechanical debridement (MD) for the treatment of diabetic subjects with peri-implant mucositis (PM). This study compared the influence of PT as an adjunct to MD for the treatment of PM in type 2 diabetic and nondiabetic patients over a 12-month follow-up period. Patients with and without type 2 diabetes were included. PM patients were categorized into 2 groups based on the treatment procedure: (1) nonsurgical + PT and (2) nonsurgical MD alone. Demographics and education statuses were recorded. Gingival index (GI) and plaque index (PI), crestal bone loss (CBL), and probing depth (PD) were measured at baseline and after 6 and 12 months. Significant differences were detected with P < .01. The hemoglobin A1c level was significantly higher in patients with diabetes at all time durations than in patients without type 2 diabetes (P < .001). Baseline GI, PI, PD, and CBL were comparable in all groups. In patients with type 2 diabetes, there was no difference in PI, GI, PD, and CBL at 6- and 12-month follow-up. In patients without type 2 diabetes, there was a significant reduction in PI (P < .01), GI (P < .01), and PD (P < .01) at 6-month and 1-year follow-up as compared with baseline. In patients without type 2 diabetes, MD with or without adjunct PT reduced soft-tissue inflammatory parameters in patients with PM.
