Scaling and root planing with enhanced root planing on healthcare for type 2 diabetes mellitus: A randomized controlled clinical trial

Background/purpose: Periodontitis is related to diabetes mellitus. However, whether periodontal therapy can affect glycemic control remains unclear. This study aims to evaluate the effects of scaling and root planing (SRP) as well as enhanced root planing (ERP) on the glycemic control and periodontal condition of patients with type 2 diabetes mellitus (T2DM) and chronic periodontitis. Materials and methods: Patients with T2DM and chronic periodontitis were randomly assigned to treatment (n = 49) and control (n = 22) groups. The treatment group was treated with SRP, whereas the control group remained untreated. After 3 months, the patients in the treatment group were randomly divided into sub-ERP (n = 25) and subprophylaxis (n = 24) groups, which were treated with ERP and prophylaxis, respectively. Results: Hemoglobin A1c and fast plasma glucose levels in the treatment group decreased after SRP treatment. The changes in the hemoglobin A1c level in this group was significantly greater than that in the control group (P < 0.05). The periodontal condition significantly improved in the treatment group compared with that in the control group (P < 0.01). The decrease in periodontal pocket depth in the sub-ERP group was more significant than that in the subprophylaxis group (P < 0.05). Conclusion: This study suggests that SRP can be of benefit for the improvement of glycemic control and periodontal condition. In addition, ERP can further improve the periodontal condition of patients with 12DM. Copyright (C) 2013, Association for Dental Sciences of the Republic of China. Published by Elsevier Taiwan LLC.
