Oral self-care and periodontal health indicators among adults with diabetes in Finland.

We assessed the effects of oral self-care on periodontal health indicators among adults with diabetes. The sample consisted of 120 dentate individuals, all of whom were regular patients at the Salo Regional Hospital Diabetes Clinic in southwest Finland. Clinical periodontal examination included identification of visible plaque, the presence of calculus, and use of the Community Periodontal Index of Treatment Needs (CPITN). A questionnaire focused on self-treatment, self-prevention, and self-diagnosis of oral diseases, utilization of dental services, and patients' knowledge and attitudes towards oral health. The New Century model of oral health promotion was used as a theoretical framework for analysis of determinants of oral self-care. Although individuals aged 40 years or older were more frequent interdental cleaners, significantly better oral health indicators were found among younger patients. Women reported brushing their teeth more frequently, and differences in plaque and calculus indices were significantly lower than those of men. Self-reported good oral condition was strongly associated with frequent dental visits and less plaque and calculus. No missing teeth and age less than 40 years were predictors of lower plaque, calculus, and CPITN scores. A significant association was found only between frequent dental visits and reduced amount of calculus. Self-reported frequency of oral health habits among adults with diabetes seemed to have little effect on periodontal health indicators. Adults with diabetes should benefit from comprehensive oral self-care, and more attention is needed for improving the quality and outcome of these habits.
