Abstract :

Aim & objective: To compare fractal dimension (FD) from digital panoramic radiographs and to correlate FD of trabecular bone pattern in missing, impacted, functional and erupting third molar. Settings & Designs: We conducted study in the Department of Oral Medicine And Radiology on digital Orthopantamograph (OPG). Material & method: 200 samples (OPG) collected from our radiology section of career post graduate institute of dental sciences and hospital, Lucknow and divided into different groups that are impacted, missing, functional and erupting molars. In this study region of interest (ROI) was arbitrary selected i.e. trabecular bone pattern of 38 region in digital orthopantamograms. ROI was selected and cropped with the help of Microsoft picture manager and fractal analysis done using by ImageJ software. Statistical analysis used: In this study student�s t test was performed and statistical analysis done. The data were analyzed in mean values, SD, SE, p respectively for different groups. Results: The results from all groups were tabulated and the data was analyzed. We compared each group with other three groups respectively. Fractal dimension came out to be significantly variable for all the groups. Conclusion: We suggest that the fractal dimension acquired from the panoramic radiograph may be a useful predictor of the tooth eruption pattern. In our study, the results are significant and encouraging but more studies required for exploring and applying in forensic odontology
