Hypothesis
Is there a correlation between tooth loss and bone mineral density in postmenopausal women?
Conclusion
Postmenopausal women with poor oral health may present reduced bone mass.
Supporting Evidence
- Women with low bone mineral density tend to lose more teeth.
- The study found a significant association between the DMFT index and bone mass.
- More than half of the women were users of hormonal therapy, which may protect against tooth loss.
- 70% of participants were non-smokers, which is a positive factor for bone health.
- Low education levels were associated with higher tooth loss and lower bone density.
Takeaway
This study found that women who lose teeth may also have weaker bones, especially after menopause.
Methodology
A cross-sectional study was conducted with 100 postmenopausal women, assessing tooth loss and bone mineral density using the DMFT index and densitometry.
Potential Biases
Potential bias due to self-reported data on education and health behaviors.
Limitations
The study did not determine if tooth loss was due to cavities or periodontal disease.
Participant Demographics
Women in postmenopausal stage, mean age 57.4 years, mostly with limited schooling.
