Abstract
Objectives
Generalized bone loss may contribute to the development of tooth loss in elderly individuals.
The aim of the study was to investigate the relationship of tooth count with hip and
spine densitometry and phalangeal quantitative ultrasound (QUS) measurements and to
compare skeletal status between women completely and partially edentulous and between
women with caries or periodontal disease.
Methods
In the study, 67 postmenopausal women (37 edentulous and 30 with partial tooth loss)
in the mean age of 62.8 ± 7.2 years were evaluated. No reasons with potential influence on bone metabolism (chronic
diseases or medications) were noted. In order to reveal the role of the factor underlying
tooth loss, all patients were also divided into subjects with caries (n = 27) and periodontal disease (n = 40). Skeletal status was assessed by dual-energy X-ray absorptiometry (DXA) at the
hip and spine (bone mineral density—BMD [g/cm2]) and by QUS at the hand proximal phalanges (amplitude-dependent speed of sound—Ad-SoS
[m/s]).
Results
Women completely and partially edentulous did not differ significantly but a tendency
to have lower values in women completely edentulous was noted. Comparisons between
women with caries and periodontitis also did not show any significant differences
(except for significantly lower Z-score of Ad-SoS in women with caries). Tooth count correlated only with hip BMD:
in the whole group (r = 0.25–0.30, p = 0.04–0.01) and in women with caries (r = 0.45–0.51, p = 0.02–0.006). In women with periodontitis tooth count correlated only with Ad-SoS (r = 0.36, p = 0.002).
Conclusion
Associations between dental and skeletal status indicate that systemic bone loss in
skeletal sites being mostly cortical may contribute to the tooth loss.
