Association between periodontal changes and osteoporosis in postmenopausal women

Abstract

Objective To investigate the possible association between periodontal changes and osteoporosis in postmenopausal women through a longitudinal study.

Methods This longitudinal study included 33 patients. The participants were divided into three groups according to the bone mineral density assessed in the lumbar region: normal bone (G1, n = 15), osteopenia (G2, n = 12) and osteoporosis (G3, n = 6). Periodontal evaluation included clinical attachment level, probing depth, gingival bleeding index and visible plaque index, evaluated by two examiners blinded to systemic bone condition. The statistical process included the t-test for paired samples, with a significance level of 5% to check for changes in periodontal parameters considered at initial and final systemic bone density.

Results The results showed that, after follow-up, there was a significant increase in gingival bleeding index in the group of women who had normal initial bone condition and progressed to osteopenia (after 3 years, 59.89%, p = 0.010) and osteoporosis (after 3 years, 74.37%, p = 0.035). In addition, the group diagnosed with osteopenia at baseline who progressed to osteoporosis after 3 years also showed a significant increase in gingival bleeding index (p < 0.001).

Conclusions The findings suggest that periodontal changes can be associated with osteoporosis in postmenopausal women.
