PurposeThe bidirectional relationship between diabetes and periodontal disease has been established. Diabetes is a risk factor for periodontal disease while periodontal disease is a complication of diabetes. The objective of this systematic review is to determine whether the administration of periodontal therapy compared to the absence of this treatment would have an impact on the diabetes control in diabetic patients with periodontitis.MethodsA literature search was conducted on four databases (PubMed, Science direct, Scopus, Cochrane) to identify randomized clinical trials investigating the effect of periodontal therapy on levels of glycated hemoglobin and fasting plasma glucose for diabetic patients diagnosed with periodontitis. The quality assessment and the risk of bias of the included studies were carried out according to the Cochrane RoB tool.ResultsFourteen studies met the criteria and were included in this systematic review. Thirteen of these studies reported that periodontal therapy reduces glycated hemoglobin levels three months after periodontal therapy. Nine of these studies investigated the effect of periodontal therapy on fasting plasma glucose levels, five of which reported statistically significant differences of blood glucose levels between diabetics who received periodontal therapy and diabetics who did not receive treatment periodontal.ConclusionThe results of this systematic review indicate that periodontal therapy can contribute to diabetes control in diabetic patients with periodontitis.Copyright © 2018 Elsevier Masson SAS.
