Abstract
Introduction: The aim was to compare the self-perceived oral health, periodontal inflammatory conditions and socioeconomic status (SES) in patients with and without prediabetes. Methods: Thirty-nine individuals [19 patients with prediabetes (test group) and 20 control individuals (control group)], at least 20 years old were included. Plaque index, bleeding on probing, probing depth (4 to <6 mm and >= 6 mm) and number of missing teeth were recorded. Fasting blood glucose levels were recorded, and marginal bone loss was measured on radiographs. SES, education status, self-perceived oral health, family history of diabetes and tobacco habits were also investigated. Results: Mean ages of individuals in the test and control groups were 40.6 and 42.3 years, respectively. Plaque index, bleeding on probing, probing depth (4 to <6 mm and >= 6 mm) and number of missing teeth were higher in the test group as compared with the control group (P < 0.05). Premolar and molar marginal bone loss was higher in the test group as compared with the control group (P < 0.001). Self-perceived bleeding gums was more often reported by individuals in the test group as compared with the control group. A poor SES and education status was higher among individuals in the test group as compared with the control group (P < 0.001). Conclusions: Self-perceived gingival bleeding and clinical periodontal inflammation were severe in patients with prediabetes as compared with controls. An underprivileged SES aggravated periodontal conditions in patients with prediabetes.
