Changes in the mandibular height and thickness of its alveolar part have been studied, with special reference to the relation existing between the apices of the molar teeth roots and the external and internal surfaces of the mandible and the mandibular canal. The investigation was carried out in 148 male and female sculls having the lower jaw, in 115 maxillodental cuts. It has been stated that the greatest mandibular height is in males at the level of the first premolar teeth (23.4+/-0.82 mm) and the smallest -- at the level of the second molar (32.01+/-0.52 mm). The thickness of the alveolar part at the level of the root apices of the first premolar is the smallest both in males and females (9.578+/-0.301 mm -- 11.068+/-0.69 mm); the greatest -- at the level of the third molar (13.0+/-0.632 mm -- 15.5+/-0.55 mm). The distance between the root apex and the external surface of the alveolar part is the least at the level of the first premolar, at an average 3.12 mm. The mandibular osseous structure and the relation of the tooth root with the mandibular canal are clearly seen in electroroentgenograms.
研究了下颌骨高度及其牙槽部分厚度的变化，特别参考了磨牙牙根尖与下颌骨内外表面及下颌管之间的关系。对148具带有下颌骨的男女颅骨以及115例上颌牙颌切片进行了调查。结果表明，男性下颌骨最高处位于第一前磨牙水平（23.4±0.82毫米），最低处位于第二磨牙水平（32.01±0.52毫米）。第一前磨牙根尖水平处牙槽部分的厚度在男性和女性中均最小（9.578±0.301毫米 - 11.068±0.69毫米）；最厚处位于第三磨牙水平（13.0±0.632毫米 - 15.5±0.55毫米）。在第一前磨牙水平，根尖与牙槽部分外表面之间的距离最短，平均为3.12毫米。在电子X线照片中可以清楚地看到下颌骨的骨质结构以及牙根与下颌管的关系。
