Objective: to identify changes of the configuration and size of the walls of the alveolar stages of ontogenesis. Materials and Methods. Orthopantomograms studied 196 children aged 5 to 12 years. We used visual and morphometric methods. Results. The data on the three diameters of the dental alveoli (proximal, middle and distal) has been presented, under which subsequently the main stages of age transformation have been highlighted. Conclusion. Transformation of the alveolar walls radiologically determined and its advancing character in relation to the macroprocesses in the germ tooth have made it possible to consider alveolus as one of the leading biological tools of odontogenesis.

Functional structure of stomodeum


Purpose: identification of the structure providing outflow of liquid from stomodeum in the process of formation. Material and Methods. 150 stomodea have been investigated for the ways of removal of liquid by the following methods: stage-by-stage freezing, contrasting and macerations. Result. One of the ways of removal of liquid from enamel of a being formed tooth is the crypt canal. Conclusion. Function of the channel of a crypt of developing teeth consists of removal of biological specific dental fluid from a surface of enamel of stomodeum in a mouth in the following options: on an oral surface of alveolar processes, near a periodontal fissure, or directly in a periodontium of a milk tooth — predecessor.
