Background: Menopause is associated with significant bone loss and worsening oral health, especially periodontal disease (PD). The purpose of this study was to understand the relationship between oral health and bone loss and the factors that influence this relationship. This will help better understand their pathophysiology and provide guidance for more appropriate care. Methods: ​​This cross-sectional study included post-menopausal women undergoing routine bone density evaluation at a diagnostic radiology center. After participants signed informed consent, histories were collected via an investigator-administered questionnaire, the oral cavity was inspected for teeth loss and PD, and a bone density assessment, interpreted by a radiologist, was obtained. The significance level was set at 5% and data were analyzed using chi-square and logistic regression tests. Results: In a sample of 100 eligible participants, the mean age and body mass index (BMI) were 68.17 ± 8.33 years and 29.59 ± 6.13 kg/m2 respectively. Twenty-three participants (23.0%) had T2DM, 29 (29.0%) had < 20 natural teeth and 17 (17.0%) had normal bone mineral density. In an unadjusted simple logistic regression, age, BMI, race/ethnicity, number of natural teeth, history of PD, and history of osteoporotic fracture were associated with bone loss. However, in the binary logistic regression, the only significant predictors of bone loss included age (aOR 1.171, p<0.001), BMI (aOR 0.763, p<0.001), and the history of osteoporotic fractures (aOR 21.273, p=0.021). Conclusion: Clinical variables associated with bone loss in our study included older age, lower BMI, and history of osteoporotic fracture. These are established risk factors for bone loss. Although unadjusted results suggest a relationship between oral health measures and bone loss, these relationships were not present when other factors were included in a multivariate model. These findings suggest PD by itself may not be a risk factor for bone loss but may reflect the similarity in the risk factors for both conditions. Presentation: 6/3/2024
