['People with diabetes have a high risk for periodontal disease, which can be considered one of the complications of diabetes. We evaluated periodontal treatment needs using the Community Periodontal Index of Treatment Needs (CPITN) in relation to diabetes-related factors and oral hygiene.', 'The sample consisted of 120 dentate diabetics, all of whom were regular patients at the Salo Regional Hospital Diabetes Clinic. The nurses, who interviewed the patients, collected data on duration and type of diabetes, complications, and HbA1c level. Clinical periodontal examination included identification of visible plaque, the presence of calculus and use of the CPITN.', 'The CPITN score 3 was the most prevalent. According to the logistic regression model, poor metabolic control was significantly related to pathologic pockets. No significant association was found between diabetes-related factors and the highest individual CPITN score of 4, which was, in turn, significantly associated with extensive calculus.'] Does assessment of periodontal treatment need among adults with diabetes in Finland?
