Mandibular Canal Course Of Dentate Subjects Using Cone-beam Computed Tomography
Objectives: To describe morphometric relationships of mandibular canal (MC) course of dentate subjects using cone-beam computed tomography (CBCT).
Methods: We carried out a descriptive, retrospective and cross-sectional study in which CBCTs of patients attended at University Dental Clinic were evaluated (after signing the respective informed consent). The sample included 55 CBCT of patients (22 men and 33 women), fully dentate until the first molar, with a mean age of 27 ± 10.43 years (25.64 ± 10.46 years for men and 27.91 ± 10.47 years for women). Multiplanar reconstructions were used and different slices at frontal view were obtained in order to measure the distances between MC and alveolar ridge (m1), MC and buccal cortical bone of jaw (m2), MC and lingual cortical bone of jaw (m3), and MC and basal cortical bone of jaw (m4). These measurements were carried out at the second premolar level (A), inter-radicular area between second premolar and first molar (B), mesial root of first molar (C), furcation level of first molar (D) and distal surface of first molar (E).
Results: The mean and standard deviations of every measurements at different levels in the MC course are presented in Table 1.
Conclusions: The MC course was observed very sinuous at different planes. For m1, the maximum distance is observed at first molar level. The MC course goes from a more buccal position at the premolar level in the bone to a lingual position behind the first molar. In addition, the MC course goes from a more superior position at the premolar level in the bone to an inferior position behind the first molar.
