Abstract
The mammalian teeth were the effective oral organ which concerned with either or and prehension, grasping, shearing, mastication, and grinding of food stuffs, in addition to offence and predation in predators. Moreover, they were utilized in clinic forensic medicine for accurate identification of the specific species and aging. This thesis aimed to highlight the study of the embryonic development of incisors in the Egyptian buffalo. The image was prepared from 24 samples from the study groups of both sexes, their ages ranged from (CVRL) scale between 2 - 98 cm and their ages between 38-295 days. Samples were prepared for physiological examination, as well as x-rays and CT scans. It has been shown through the study that the embryonic development of the deciduous incisors passes through several successive stages, beginning with the stage of emergence, then accretion, then cellular differentiation, and the excretion of enamel and dentin substances and ends with calcium deposition, ossification, and emergence in the oral cavity. Tooth formation begins with the emergence of a thick epithelial strip of oral epithelial cells at a length of 2 cm (38 days), followed by the dental plaque at 5-7 cm (52-61 days), followed by the epithelium and tooth germs at 9 cm (70 days). The formation of the tooth begins with the appearance of the enamel organ in a vaulted shape at a length of 13-16 cm (88-101 days), then it takes a bell shape at a length of 20-22 cm (119-124 days). Cellular differentiation begins with the differentiation of the cells that make up the dentin, the dental pulp and the retinal capsule at length 25-32 cm (130-136 days). The secretion of dentin and enamel begins at 38-48 cm (160-182 days) in length, calcium precipitation begins at 56-68 cm (200-227 days), and incisors begin to erupt at 76 cm (245 days) in length and complete their appearance at 90-98 cm (267 days). 295 days).
