Panoramic Radiograph and cone beam computed tomography- evaluation of Mandibular impacted third molar and Mandibular canal
نویسندگان
چکیده
Methods: The sample consisted of 20 subjects (20 left and 20 right mandibular third molars) who underwent pre-operative radiographic evaluation before extraction of impacted mandibular third molars. On panoramic radiographs, the most common high risk injury signs of inferior alveolar nerve (darkening of roots, interruption of white line, deviation of mandibular canal, narrowing of mandibular canal and superimposition of mandibular canal on roots) and bucco-lingual position of mandibular canal, supero-inferior position of mandibular canal, presence or absence of corticalisation between the mandibular third molar and the mandibular canal and cortical plate perforation on cone beam computed tomographic (CBCT) images were evaluated.
