Screening for prediabetes and risk of periodontal disease

Diabetes and periodontitis are non-transmissible chronic disorders that exhibit a mutual relationship. A study was made to evaluate the risk of prediabetes and periodontal disease, and to explore the association between them.

A descriptive cross-sectional study was made of 186 individuals over 18 years of age, without prediabetes or diabetes, or cognitive impairment. Subjects undergoing dental treatment and pregnant women were excluded. Prediabetes risk was assessed based on the Finnish Diabetes Risk Score (FINDRISC), and the individual risk of development and/or progression of periodontal disease was explored with a periodontal disease risk questionnaire.

A total of 135 gingival risk questionnaires and 142 FINDRISC questionnaires were correctly completed. The proportion of subjects with a low, moderate and high risk of periodontal disease was 60.36%, 38.74% and 0.9%, respectively. With regard to the FINDRISC, the proportion of individuals with low, slightly increased, moderately increased and high risk of prediabetes was 54.4%, 32.8%, 8%, and 4.8%, respectively. A significant linear correlation between the two scores was observed (r = 0.3659, p < 0.0005). The variables associated with a slightly increased risk of prediabetes were age, overweight and smoking, while the variables associated with a moderately increased or high risk were age 40-65 years, tooth loss, overweight and smoking.

These questionnaires may be of benefit to patients and can contribute to develop a chronic care model characterized by collaboration among different healthcare professionals.
