Topographic, Morphological and Morphometric Investigation of Mandible in Norduz Sheep

Abstract

In order to contribute to animal welfare, veterinary maxillofacial surgery is one of the fields of science that requires deep anatomical knowledge about the region. Therefore, in this study, it was aimed to define the mandible by using macroanatomical, morometric and topographic methods to understand the morphophysiology of the mandible in Norduz sheep. Norduz sheep mandibles of 10 male animals were used. Mandibles were first examined with classical morphometric and topographic methods. It was seen that the mandible consisted of corpus, ramus and angulus parts. It was observed that the foramen mentale was oval and round in shape and in different numbers on the lateral edge of the mandible. It was observed that the foramen mandible was elliptical. According to the statistical analysis, mandible length was measured as 149.12±4.75 mm on the right side and 148.12±4.50 mm on the left side in Norduz sheep. Mandible height was analyzed as 160.81±4.72 mm on the right side and 160.74 mm on the left side. The distance of the foramen mandible to the infradental space was 127.85±4.62 mm on the right and 125.31±4.11 mm on the left. Diastema length was analyzed as 38.05±1.34 on the right side and 40.87±2.81 on the left side. The length of the premolar and molar teeth on the margo alveolaris of the mandible was 56.69±2.38 mm on the right side and 54.13±2.73 mm on the left side. The distance of the foramen mentale to the gonion caudale was analyzed as 118.34±4.22 mm on the right and 118.90±4.12 mm on the left. According to the statistical analysis, L17 measured over the right and left mandibles was statistically significant (p
