Objectives:
The aim of this study was to evaluate the distance of the mandibular 2nd premolar, 1st and 2nd molar apexes from the mandibular canal.
Material and Methods:
Cone Beam Computed Tomography images of 99 patients aged 16-60 years (n = 99) obtained from the database archive of Akdeniz University Faculty of Dentistry Department of Maxillofacial Radiology were analyzed. The study groups were divided into 3 groups as 16-30 (Group 1), 31-45 (Group 2), <45 (Group 3) and equal number of participants were included in each study group. Of the 99 participants, 51 (51.5%) were male and 48 (49.5%) were female. In coronal sections, the distance between the mandibular 2nd premolar apex, the mesial and distal root apices of the 1st and 2nd molars and the upper border of the mandibular canal was calculated in millimeters (mm). In our study, differences according to age and gender were also analyzed.
Results:
When the apex-mandibular canal distance of the 2nd molars of both quadrants were analyzed in terms of both mesial and distal roots, they were statistically closer than the teeth in the same quadrant (P < 0.05). While the root apexes of the teeth evaluated in Group 1 were significantly closer to the mandibular canal, the distances of the apexes of Group 3 to the mandibular canal were significantly farther (P < 0.05). In terms of gender, the apex-to-mandibular canal distance of female subjects was significantly lower than that of male subjects (P < 0.05).
Conclusion:
In dentistry, before surgical and endodontic treatments to be applied to mandibular posterior teeth, a 3D examination should be performed and the proximity of the roots with the mandibular canal should be taken into consideration. This is very important to prevent nerve damage and increase treatment success.
