The morphologic occurrence of dens invaginatus often results in pathologic involvement of the pulp and associated periodontal tissues. Treatment must include endodontic therapy to reduce the organic and infectious content of the pulp and invaginated tract. Concervative therapy, however, is frequently insufficient to eliminate the irritant force to a level that is biologically acceptable to the host. Therefore, surgical intervention has been considered by most authors to be the most acceptable approach for correction of the deformity and associated alveolar defects. Both cases reviewed here represent the dens invaginatus type of malformations that have primary zones of irritation within the anomalous tract. A report similar to our Case 2 appeared in the literature 2 weeks after initial therapy of the nonpupally involved lateral incisor. These cases are published to document the occurrence of these forms of dens invaginatus and their associated periradicular pathosis, to recommend treatment, and to note the apparent favorable response to the involved tissues.
牙中牙的形态学表现常导致牙髓及相关牙周组织的病理改变。治疗必须包括牙髓治疗，以减少牙髓和陷入道内的有机物和感染物质。然而，保守治疗往往不足以将刺激因素消除到宿主生物学可接受的水平。因此，大多数作者认为手术干预是矫正畸形和相关牙槽骨缺损最可接受的方法。这里回顾的两个病例均代表牙中牙类型的畸形，在异常管道内有主要刺激区域。在对未累及牙髓的侧切牙进行初始治疗2周后，文献中出现了一篇与我们的病例2类似的报告。发表这些病例是为了记录这些类型牙中牙的发生情况及其相关的根尖周病变，推荐治疗方法，并指出对受累组织明显的良好反应。
