A COMPARATIVE STUDY OF RADIOLUCENT JAW LESIONS BETWEEN PANORAMIC RADIOGRAPHY AND CBCT

The AIM of this study was to compare the radiographic features of intraosseous radiolucent lesions of the jaws in panoramic radiographs (PRs) and in cone beam computed tomography studies (CBCT). Materials and METHODS : We analyzed 19 patients aged 12 to 76 years 44 years average from Department of Surgery , Faculty of Dentistry , UBA presenting well-defined radiolucent lesions of ≥ 1.5 cm in diameter in the jaws. The lesions were located 2 in anterior maxilla and the rest in the lower jaw. All patients were examined with panoramic Team Cranex (Finland) and Kodak 9000C 3D CBCT prior to surgical intervention. Radiographic findings were analyzed classifying them as: location, shape, size, margins, density, bone effect, tooth effect. Each case was documented clinically and radiographically. The location of the lesions were classified intraosseous maxillary anterior (midline to distal of canine), medium (first premolar mesial to distal of the third molar) and tuberosity. Similarly pooled involving the mandible in the posterior angle, branch, condyle and coronoid process. The images were analyzed by three radiologists calibrated. RESULTS: The comparison was made between PR and CBCT based on quantitative variables horizontal and vertical dimension using a factorial ANOVA and multiple comparison tests using the Wilks Lambda test , studied data show no significant differences between operators nor between methods. Comparison is made between PR and CBCT based on scale variables for the test trials was chosen nonparametric Mann - Whitney U- test showed significant differences for these variables bony walls , erosion of the cortical and cortical reaction . CONCLUSION: With this tool you can get diagnosed volumetric features and make a careful analysis of the radiological parameters of the lesion in three dimensions.
