Özet:

The mandibular nerve, which runs within the canalis mandibularis, is called nervus mentalis when it leaves the canal from the mental foramen. The innervation areas of these two different nerves are different. Therefore, in order to provide anesthetic blockade of the regions innervated by these two nerves, the region should be well known anatomically and topographically, and reference points should be determined well. Therefore, in this study, macroanatomical, morphometric, topographic and radiological methods were used to understand the anatomy of the mandible of Norduz sheep, which is one of the important gene sources in our country, where breeding is important. In this study, 10 female Norduz sheep mandibles were used. Mandibles were first examined with classical methods, macroanatomical, morphometric and topographic methods. Later, MR images were taken in the radiology unit. It was observed that the last molar teeth on the Margo alveolaris did not protrude from the alveolar cavity in any of the materials. It was observed that the premolar teeth consisted of 3 roots in forty percent of the material, and two roots in sixty percent. It was observed that the mental foramen was oval and round in shape and was located on the lateral surface of the mandible in different numbers. It was observed that the foramen mandible was elliptical. According to the statistical analysis, the length of the mandibula in the noble sheep was measured as 146.93±2.95 mm, on the right and 147.91±3.32 mm, on the left. The distance of the condylar process to the infradental space was analyzed as 165.15±2.62 mm, on the right and 162.43±2.97 mm, on the left. The height of the mandible was 87.87±0.75 mm, on the right and 88.00±0.81 mm, on the left. The length of the interalveolar region was measured as 35.69±0.61 mm, on the right side and 36.67±0.72 mm, on the left side. Statistically analyzed parameters did not show a significant value between the mandibles in terms of direction (p>0.05).
