Summary

Dental panoramic tomograms can help identify perimenopausal women at risk for low skeletal bone mass. A narrow mental index (MI), low body mass index (BMI), or high osteoporosis risk score (SCORE) are significant indicators.

Area of Science:

  • Osteoporosis Research
  • Dental Radiology
  • Geriatric Health

Background:

  • Low skeletal bone mass, including osteoporosis, is a significant health concern for perimenopausal women.
  • Early detection of low bone mass is crucial for timely intervention and prevention of fractures.
  • Clinical and radiographic indices offer potential non-invasive methods for assessing bone health.

Purpose of the Study:

  • To evaluate the diagnostic utility of clinical and radiographic indices for identifying low skeletal bone mass in healthy perimenopausal women.
  • To determine the correlation between mandibular bone measurements and overall skeletal bone density.
  • To assess the predictive value of Body Mass Index (BMI) and Osteoporosis Risk Estimation (SCORE) in conjunction with dental radiographic findings.

Main Methods:

  • Dual-energy X-ray absorptiometry (DXA) was used to measure bone mineral density (BMD) in the spine and femoral neck.
  • Dental panoramic tomograms were analyzed to measure the mental index (MI), representing mandibular cortical width.
  • Body Mass Index (BMI) and Simple Calculated Osteoporosis Risk Estimation (SCORE) were calculated for each participant.

Main Results:

  • The SCORE index was a significant predictor of low bone mass, primarily influenced by patient weight.
  • Significant correlations were observed between skeletal bone density and the mental index (MI), BMI, and SCORE.
  • A logistic regression model incorporating MI, BMI, and SCORE demonstrated all three as significant predictors of low skeletal bone mass.

Conclusions:

  • A reduced mental index (MI < 3mm) in perimenopausal women is associated with lower skeletal bone mass.
  • Underweight status (BMI < 20kg/m²) or a high SCORE index (≥6) further increases the risk of osteoporosis in these women.
  • Dental radiographic assessment, particularly the mental index, can serve as a valuable tool in the early screening for osteoporosis risk.
