Brief summary: Unfavorable systemic conditions condition a low resistance of the host to the virulence of the aggressive agent, causing in a periodontal disease and may lead to difficulties in the therapeutic response. The longer the duration of diabetes, it is suggested that greater severity of periodontal disease and loss of insertion. The objective of the present study will be to evaluate the clinical, microbial and immunological characteristics in diabetic subjects with chronic periodontitis submitted to non-surgical periodontal treatment. Will be 120 individuals with chronic periodontitis, including 60 type 2 diabetic subjects and 60 healthy should receive and have access to the informed consent form. Medical and dental clinical examination should be performed and evaluation microbial and immunological properties of gingival fluid and saliva respectively. Non-surgical periodontal therapy with subgingival scaling should be performed in all individuals who will be evaluated at two times: at the beginning and after 90 days of the periodontal therapy with new performing clinical exams and collecting oral samples, oral hygiene instructions will be addressed in two sessions. The data will be subjected to appropriate statistical tests and shall provide a comparison between the times. There seems to be a relationship between type 2 diabetes and periodontal disease and studies that provide the implementation of therapy are essential for clarifying the relationship.

Detailed description: There is a need for more intense metabolic control of the diabetic patient with periodontal disease, since the destruction of the periodontal tissues may be more aggressive, and a rapid control of the oral infection in these patients is essential to avoid the exacerbation of the metabolic imbalance. The initiation and progression of diabetes probably involve the interaction of a multiplicity of factors, these being hereditary and immunological factors that are governed by environmental factors. It can be observed that there is a lack of awareness of oral complications between diabetics and health care providers, and it is extremely important to understand how diabetes affects oral health and there is a need for regular follow-up of patients with diabetes mellitus by dentists and medical professional. The objective of the present study was to evaluate diabetic individuals with chronic periodontitis submitted to non-surgical periodontal treatment using clinical parameters and blood tests of fasting glycemia and glycated hemoglobin. The study was approved by the Research Committee of the Metropolitan University of Santos, nº 1.806.841 and all the patients involved in the research had access to the informed consent form. The diagnosis of diabetes was obtained through blood tests that test blood glucose levels, thus, before clinical evaluations, and 90 days after the periodontal treatment were performed fasting blood glucose tests. Healthy patients also underwent blood tests. After the anamnesis, periodontal clinical examination was performed by a previously trained and calibrated periodontist. Periodontal clinical parameters were realized. After periodontal therapy, all patients underwent further periodontal and laboratory blood tests. The data obtained were tabulated and received statistical treatment through the Anova and Chi square tests. There seems to be a relationship between type 2 diabetes and periodontal disease and studies that provide the implementation of therapy are essential for clarifying the relationship.
