Endodontic and periapical status of patients with osteoporosis: A cross-sectional study with age- and sex-matched controls.

BACKGROUND

The aim of the authors was to evaluate the periapical and endodontic conditions of patients with osteoporosis and compare them with those of age- and sex-matched controls. The association between bisphosphonate (BiP) use and periapical and endodontic status in patients with osteoporosis was also investigated.

METHODS

Panoramic radiographs of 711 patients with osteoporosis and 711 age- and sex-matched healthy patients were examined. The presence and number of root canal-filled teeth (RCFT), inadequate RCFT (iRCFT), and teeth with apical periodontitis (AP) were evaluated. BiP treatment history of patients with osteoporosis was also recorded.

RESULTS

No significant difference was observed between the osteoporosis group and control group in terms of endodontic and periapical conditions. Results of bivariate logistic regression analysis showed a positive association between the number of teeth with AP and the number of iRCFT with AP and osteoporosis, and a negative association between the number of RCFT with AP and osteoporosis. Among the patients with osteoporosis, 37.5% used BiPs, specifically alendronate, ibandronate, zoledronate, and risedronate (34.3%, 24.9%, 10.6%, 7.2%, respectively). In addition, the results showed a negative association between BiP use and RCFT.

CONCLUSIONS

As the number of teeth with AP and number of iRCFT with AP increased, patients were more likely to be in the osteoporosis group. These findings imply that periapical lesions may enlarge and become more detectable in patients with osteoporosis with lower bone density, and enhanced inflammatory response.

PRACTICAL IMPLICATIONS: Dentists can collaborate with health care professionals to manage the overall health of patients with osteoporosis to reduce the impact of osteoporosis on oral health and effectively treat dental problems, such as AP.
