The publication summarizes the literature on the development of human dentition based on the original 3D reconstructions, supplemented by specific aspects of the development of the upper and lower jaws in order to understand the emergence of some pathologies in the orofacial region. In contrast to the generally accepted view of the development of human temporary dentition, which describes the formation of dental teeth from the dental tract and the formation of vestibules oris from the externally placed vestibular trunk, there is a summary of recent data on the development of vestibulum oris, whose basis of development is the system epithelial structures appearing prenatally in the area externally from the dental bases that repeatedly fuse with the dental strip and in certain areas may temporarily resemble dental bases. The epithelial structures externally from the dental strip are related as a possible pathogenetic developmental basis to odontogenic tumors and cysts that may form externally from the dental arch in humans and whose origin is not yet clearly elucidated. Emphasis is also placed on the specifics of the development of the upper lateral incisor, the embryonic base of which carries the material of two different facial processes - medial nasal and maxillary, thus explaining the high developmental fragility of this tooth and the frequent defects associated with facial clefts.
