Peculiarities of odontometric parameters among young women with various types of face

Abstract

The study of odontometric parameters seems to be relevant for the development and improvement of new methods for diagnosis and prediction of dental diseases. The study objective is to make a comparative analysis of the size of the crowns of the teeth of the upper and lower jaws, depending on the type of face. Material and methods. Odontometric and cephalometric parameters were studied, the research was conducted on 192 girls aged 17 to 20 years. Cephalometric program included the definition of the zygomatic diameter and the upper facial height with the subsequent calculation of the facial index. The face types were determined based on the value of this index. Odontometric parameters were recorded by impressions of the upper and lower jaws. Results. Reliable differences were found: a wide type of face is associated with smaller mesiodistal sizes of the crowns of the maxillary first molars, maxillary lateral incisors and maxillary canines, as well as with a lower height of the crowns of the mandibular canines. With a narrow type of face, the opposite pattern was revealed - all the above mentioned parameters in this case are higher than those of euryens. Dimensional characteristics of teeth with a medium broad face are characterized by intermediate values between the extreme types of face. Conclusion. On the basis of odontometric and cephalometric studies, the comparative analysis of the size of the crowns of the teeth of the upper and lower jaws is given depending on the type of face. It was revealed that odontometry indicators have specific features depending on the type of face. The new data obtained as a result of the research supplement and expand already known information about the parameters studied, both in theoretical and practical aspects.
