Summary
This study developed reliable new software for radiodensitometric evaluations, showing high correlation with bone mineral density (BMD) measurements. Further research is needed to confirm its clinical applicability.
Area of Science:
- Dentistry
- Radiology
- Medical Imaging
Background:
- Radiodensitometry offers a non-invasive method for assessing bone mineral density (BMD).
- Accurate and reliable software tools are crucial for precise radiodensitometric evaluations.
Purpose of the Study:
- To evaluate the accuracy and reliability of novel MevisLab software for radiodensitometric analysis.
- To compare software-derived densitometric values with established bone mineral density measurements.
Main Methods:
- Intraoral radiographs of the premolar region were analyzed using MevisLab software.
- An aluminum step wedge was used for calibration; grey values were converted to aluminum equivalence (mm Al eq.).
- Software-derived BMD was compared with dual X-ray absorptiometry (DXA) and decalcified bone specimens.
Main Results:
- Laboratory study showed a high correlation (r=0.96) between densitometric data and jaw bone BMD.
- In vivo studies demonstrated moderate correlations between densitometric data and lumbar spine, hip, and femoral neck BMD.
- Excellent intraobserver (±0.15 mm Al eq.) and interobserver (±0.11 mm Al eq.) reliability was observed.
Conclusions:
- The developed MevisLab software demonstrates reliability for bone density assessment.
- Further large-scale studies are warranted to validate its clinical accuracy and applicability.
