Objective: to improve the understanding of X-ray features of the odontogenic keratocyst of mandibula.
目的：提高对牙源性角化囊肿X线征象的认识。
The periodontal ligament is a connective tissue located between the cementum of teeth and the alveolar bone of the mandibula.
牙周膜是位于牙骨质和下颌骨的齿槽骨之间的结缔组织。
Results: Pilot model of mandibula, built with paper was modelled, the dimensions of the model were in agreement with the mandibula specimen.
结果： 得到了下颌骨纸质实物模型，其几何外形与下颌骨标本基本一致。
Results Gallium chloride could increase the bone density of mandibula, widen the average width of the bone trabecular, and decrease the ration of the bone trabecular contents.
结果镓盐治疗可引起大鼠颌骨骨密度增加，颌骨的平均骨小梁宽度、骨小梁百分比增加，骨小梁间距变小。
