Morphometrical variability of dental alveoli of mandible in adults

Objective: to determine the morphometrical variability of dental alveoli bilaterally, depending on their position in the alveolar part of the mandible. Material and Methods. The object of the study is to certify 70 cranions with mandibles of middle-aged adults (21-60 years) and 30 isolated mandibles without gender-and age-related characteristics. The objects of the study were taken from scientific cranial fundamental museum collection of the Department of Human Anatomy. For the scientific research Craniometry method was used according to generally accepted craniology process parameters. Dental alveoli on both sides of the mandible were studied. Results. It was established that longitudinal diameter prevails at tooth alveoli of a canine, the first and second premolars, cross diameter on the same side of a jaw at the left — at alveoli of a medial incisor and the first premolar in comparison with its right side. At dental alveoli the left-sided depth is larger of the first molar, of the second molar — the right-sided is larger. Longitudinally cross diameter in the direction from alveoli of front teeth to back ones increases at each subsequent alveolus, since the minimum size at incisors and reaching the maximum size at alveoli of the first and second molars. The largest depth of tooth alveoli is determined at a canine, the first and second premolars. Conclusion. Results of the research of bilateral and individual variability of parameters of tooth cells may be used in practical stomatology.
