Accuracy and Reliability of Ultra Low Dose CBCT Versus CBCT Imaging in Semi-automated Segmentation of the Mandibular Condyle (A Diagnostic Accuracy Study)

The objective of this study will be evaluation of accuracy and reliability of CBCT imaging versus Ultra low dose CBCT imaging in semi-automated mandibular condyle segmentation (linear and volumetric assessment of the condyles), in cases requiring condylar and mandibular reconstruction. Dry human skulls and dry human mandibles will be recruited from Anatomy Department, Faculty of Medicine, Cairo University. The following radiographic examination will be done in Oral and Maxillofacial Radiology Department, Faculty Dentistry, Cairo University. they include Radiographic imaging by CBCT machine \& Data acquisition and analysis. then semiautomated segmentation will be performed for the mandibular condyles and then after the assessment will be done as both linear and volumetric for each condyle.
