Background: There is a high prevalence of periodontal disease (PD) and bone loss (osteopenia and osteoporosis) among patients with diabetes. Understanding the relationship between these conditions in the context of type 2 diabetes (T2DM) as a risk factor will help better understand their pathophysiology and provide guidance for more appropriate care. Methods: This was a cross-sectional study that enrolled post-menopausal women presenting for routine bone density evaluation. Following informed consent, we obtained information about their demographics, diabetes status, and dental history using an investigator-administered questionnaire. We measured their height and weight with a stadiometer and inspected their oral cavity for teeth loss and PD. We then obtained their bone density assessment after interpretation by the radiologist. Data were analyzed using chi-square and logistic regression tests with the significance level set at 5%. Results: Among 66 eligible participants, the mean age and body mass index (BMI) were 67.67 ± 8.1 years and 29.76 ± 5.45 kg/m2 respectively. Twelve participants (18.2%) had T2DM, 19 (28.8%) had < 20 natural teeth and 17 (25.8%) had normal bone mineral density. Using a binary logistic regression, significant predictors of bone loss included age (OR 1.217, p=0.008), BMI (OR 0.827, p=0.04), and a diagnosis of T2DM (OR 0.056, p=0.033). The number of natural teeth, number of broken or decayed teeth, and presence of periodontal disease were not associated with bone loss. Conclusion: Among our population of post-menopausal women, clinical variables associated with bone loss included older age and lower BMI. Having T2DM was associated with a higher bone mineral density which does not translate to stronger bones according to previous reports. Oral health outcomes were not associated with bone loss and may reflect the similarity in the risk factors for the two conditions. Presentation: Thursday, June 15, 2023
