Abstract

Objective: To evaluate the association between dental characteristics and osteoporosis in postmenopausal women. Subjects and Methods: A cross-sectional descriptive study was conducted on 100 postmenopausal women diagnosed with osteoporosis (T-score ≤ –2.5 according to WHO criteria), aged between 55 and 70 years. Dental status was assessed by the number of remaining teeth, alveolar bone loss measured via periapical radiographs, and the Community Periodontal Index (CPI). Data were analyzed using SPSS version 22.0. Chi-square tests and multivariable logistic regression were used to determine associations. Results: Among the 100 participants, 67% had fewer than 20 remaining teeth. The mean level of alveolar bone loss was significantly higher in patients with T-scores ≤ –3.0 compared to those with T-scores from –2.5 to –3.0 (p < 0.05). The CPI indicated that 56% of patients had moderate to severe periodontitis. Multivariable logistic regression analysis showed that severe osteoporosis (T-score ≤ –3.0) was an independent risk factor for tooth loss (OR = 2.48; 95% CI: 1.12–5.50; p = 0.024). Conclusion: Postmenopausal osteoporosis is associated with tooth loss and alveolar bone resorption. Interdisciplinary collaboration between endocrinology and dentistry is necessary for comprehensive management of postmenopausal osteoporosis patients.
