To estimate the association between osteoporosis treatment and severe periodontitis in postmenopausal women.
Excessive bone resorption occurs in both
osteoporosis and periodontitis. The study explains the positive relationship of
estrogen therapy for postmenopausal osteoporosis and prevalence of severe
periodontitis.
To estimate the
association between osteoporosis treatment and severe periodontitis in
postmenopausal women.
This cross-sectional study
comprised of 492 postmenopausal women, 113 women in osteoporosis treatment, and
379 not treated. Osteoporosis treatment consisted of systemic estrogen alone,
or estrogen plus progestin, and calcium and vitamin D supplements, for at least
6 months. Severe periodontitis was defined as at least two interproximal tooth
sites with clinical attachment loss of at least 6 mm, and at least one
interproximal site with probing depth of at least 5 mm; and dental caries
experience was measured using the decayed, missing, and filled teeth (DMFT)
index. Analysis included descriptive statistics and Poisson multivariate
analysis with robust variance.
Women receiving
osteoporosis treatment had less periodontal probing depth, less clinical
attachment loss, and less gingival bleeding than women not receiving treatment
for osteoporosis (P ≤ 0.05). In the osteoporosis treatment group, the estimated
mean DMFT index score was approximately 20, the most frequent component being
the number of missing teeth, and in the nontreated group, the DMFT index was approximately
19. The prevalence of severe periodontitis was 44% lower in the osteoporosis
treatment group than in the nontreatment group. The prevalence ratio adjusted
was 0.56, 95% confidence interval was 0.31 to 0.99 (P = 0.05), after
adjustments for smoking, age, family income, and visit to the dentist.
The results suggest that women treated with
estrogen for postmenopausal osteoporosis have a lower prevalence of severe
periodontitis than women not receiving treatment.
