Histomorphological features of the tubular system teeth in dogs

The article presents the results of micromorphological studies of dog teeth, which describe the features of the dentine tubule branches forming a tubular system. The research materials were single-root teeth clips, which were made according to a generally accepted method. It has been shown that dentin makes up the bulk of the dental organ in dogs, built from the basic substance and the tubules or tubules passing through it. Dentine tubules have a strictly defined vector of directions, which has an odontoanatomic constructive pattern. It reflects a morphofunctional feature in the form of the formation of a radially branched network. The results show that in addition to the matrix structure, the tubular system has odontoregional morphological properties, reflecting the affiliation of parts of the tubular system to the root or crown area of the dental organ in dogs. The transition from the crown part of the tooth to its root part is reflected by a change in the vector of the dentine tubules, which thereby serves as a characteristic species and breed feature of the tubular system of the dental organ of dogs.
