Co-Occurrence of Dental Caries and Periodontitis: Multilevel Modelling Approach
Objectives: To assess co-occurrence of dental caries and periodontal inflammation indicators on the same teeth.
Methods: A stratified random sample of 1405 34-78-year-olds was recruited during the Lithuanian National Oral Health Survey (response rate 52 %). Information about sociodemographic (age, sex, education, residence), behavioral (sugar-containing diet, tooth brushing frequency, use of interdental care products, last dental visit, smoking) and biological (systemic disease, use of medication, xerostomia) determinants was collected using the World Health Organization (WHO) Oral Health Questionnaire for Adults supplemented with additional questions. Clinical data was collected by one trained and calibrated examiner using the WHO criteria. Dental caries status was measured as decayed, filled teeth (DFT) and included proximal, buccal and oral surfaces. Bleeding on probing (BOP) and probing pocket depth (PPD) were assessed at six tooth sites. The highest PPD measurement per tooth was selected and dichotomized into absence or presence of 4+ mm PPD. BOP was recorded as presence or absence of the condition at a tooth level. Multilevel binary logistic regression analyses were employed using BOP and PPD as outcomes, adjusted for determinants and included interaction terms.
Results: Associations between DFT and BOP (OR 1.97, 95% CI 1.84-2.19) and DFT and PPD (OR 2.13, 95% CI 1.90-2.40) were found. The effect of DFT on the probability of BOP was stronger in older age and if participant had no systemic disease. The effect of DFT on the probability of PPD was stronger if an individual did not use interdental care products.
Conclusions: The results of this study support evidence of co-occurrence of dental caries and periodontal inflammation indicators on the same teeth. Longitudinal studies to validate our results on a tooth surface level are warranted.
