In addition, the conventional radiographs could not locate the mandible’s buccolingual dimension(13,14). Before CBCT, only cadaver studies could be used to obtain similar information(15). Findings from studies using cadavers may not be generalized to patient populations due to dissimilarity of age or disease is an example of remarkable limitations concerning the intrabony anatomy of the inferior alveolar canal. In addition, dry skull studies are short of relevant data, i.e. age, gender, an inconsistent usage and anatomically irrelevant landmarks, or edentulous mandibles (16,17).
