Summary
Panoramic radiomorphometric indices like the mental index (MI) and mandibular cortical index (MCI) can help identify osteoporosis. The mandibular cortical index (MCI) demonstrated the highest reproducibility in this study.
Area of Science:
- Dentistry
- Radiology
- Osteoporosis Research
Background:
- Osteoporosis diagnosis often relies on bone mineral density (BMD) scans.
- Panoramic radiomorphometric indices offer a potential alternative or supplementary diagnostic tool.
Purpose of the Study:
- To assess the utility of panoramic radiomorphometric indices (MCI, MI, PMI) for osteoporosis identification.
- To evaluate the reproducibility and diagnostic accuracy of these indices.
Main Methods:
- Included 100 healthy women aged 30+ years.
- Acquired digital panoramic images and lumbar spine BMD.
- Measured and categorized mandibular cortical index (MCI), mental index (MI), and panoramic mandibular index (PMI).
Main Results:
- High interobserver agreement for MCI (kappa=0.922) and PMI (alpha=0.902).
- MI, PMI, and BMD positively correlated with t-score (r=0.47, 0.36, 0.96).
- MCI showed higher diagnostic accuracy (72%) than MI (63%).
Conclusions:
- Panoramic indices (MI, PMI, MCI) correlate with lumbar spine BMD and t-score.
- MCI is the most reproducible index among those evaluated.
- These indices show promise for osteoporosis screening in dental panoramic radiography.
