Summary
Fractal Dimension (FD) and Lacunarity (L) analysis can distinguish between Class 1 and other mandibular cortical shapes on panoramic radiographs. However, FD and L cannot differentiate between Class 2 and Class 3 shapes.
Area of Science:
- Radiology
- Biomedical Imaging
- Quantitative Morphology
Background:
- Mandibular cortical shape analysis is crucial in diagnosing various conditions.
- Traditional methods may lack quantitative precision.
- Fractal analysis offers novel quantitative approaches.
Purpose of the Study:
- To evaluate the efficacy of Fractal Dimension (FD) and Lacunarity (L) in discriminating different mandibular cortical shapes.
- To assess the diagnostic potential of these fractal parameters on panoramic radiographs.
Main Methods:
- Panoramic radiographs from 52 patients were analyzed for mandibular cortical index (Cl 1, Cl 2, Cl 3).
- Radiographs were converted to binary images for analysis.
- FD and L were calculated on representative cortical regions.
Main Results:
- Statistically significant differences in FD and L were found between Cl 1 and Cl 2 (P<0.001) and between Cl 1 and Cl 3 (P<0.01).
- No significant differences in FD and L were observed between Cl 2 and Cl 3 (P>0.001).
Conclusions:
- FD and L effectively differentiate Class 1 mandibular cortical shape from Class 2 and Class 3.
- FD and L cannot reliably distinguish between Class 2 and Class 3 mandibular cortical shapes using panoramic radiography.
