Periodontitis is an oral health problem that has a fairly high prevalence in the community reaches 96,58% closely related to systemic disease such as Diabetes Melitus. The purpose of this study to analyze the results of blood sugar levels taken from periodontal pockets and the fingertips of patients with type 2 diabetes melitus and compares the results of blood sugar levels taken from the periodontal pocket with the tip of a finger in patients with type 2 diabetes melitus. This Research Methode is checked his blood sugar levels were taken at the time of gingival probing and pricking fingertips using Accu-check Glucometer Nano Performance. Statistical analysis using Student's t-test and Pearson correlation significance test The Results of this study is Here were no differences in blood sugar levels when (mg / dl) in both chronic periodontitis with diabetes mellitus and without diabetes mellitus between the fingertips and the periodontal pocket with a p-value ≥ 0.0 5, where the p-value in patients diabetes mellitus 0.911 and p-value 0.982 without diabetes mellitus. Finaly Examination of the blood sugar levels of periodontal pockets during the examination together with blood sugar levels while at the fingertips, so that the inspection can be done at the dentist's office without going to the laboratorium.

Introduction Periodontitis is the most common disease in the supporting tissues of the teeth involving the gingiva, cementum, periodontal ligament, alveolar bone associated with plaque involvement. In general, periodontitis begins with gingivitis, but not every gingivitis develops into periodontitis. This condition is influenced by the number and level of virulence of microorganisms that develop in the body's response as an immune defense, as well as genetic and hereditary factors.[1],[2],[3]. Periodontal disease is a dental and oral health problem which has a high prevalence in the community reaching 96.58% in all age group. Periodontal disease is closely related to systemic ICEASD 2019, April 01-02, Indonesia Copyright © 2019 EAI DOI 10.4108/eai.1-4-2019.2287281
