不同类型的牙根吸收的病因学需要两个阶段：保护组织的机械或化学损伤和感染或压力的刺激。不同类型的牙根吸收损伤相似。治疗方法的选择与刺激因素有关。髓内感染是内根吸收和外根周围炎性根吸收的刺激因素。充分的根管治疗控制牙髓内细菌和逮捕再吸收过程。在颈部牙根吸收中，感染起源于牙周沟并刺激病理过程。由于不太可能充分控制沟内的感染，因此需要从吸收陷窝中清除肉芽组织并进行密封。去除刺激因素，即压力，是正畸治疗期间与压力相关的牙根吸收或阻生牙齿或肿瘤的治疗选择。在强直性牙根吸收中，没有已知的刺激因素;因此，没有可预测的治疗建议。因此，根据刺激因素的不同，可将各种类型的牙根吸收分为：牙髓感染性吸收、牙周感染性吸收、正畸压力性吸收、阻生牙或肿瘤压力性吸收和强直性吸收。
Etiology of different types of root resorption requires two phases: mechanical or chemical injury to the protective tissues and stimulation by infection or pressure. Injury can be similar in various types of root resorption. The selection of proper treatment is related to the stimulation factors. Intrapulpal infection is the stimulation factor in internal root resorption and external periradicular inflammatory root resorption. Adequate root canal treatment controls intrapulpal bacteria and arrests the resorption process. In cervical root resorption, infection originates from the periodontal sulcus and stimulates the pathological process. As adequate infection control in the sulcus is unlikely, removal of granulation tissue from the resorption lacuna and sealing are necessary for repair. Removal of the stimulation factor, i.e. pressure, is the treatment of choice in root resorption related to pressure during orthodontic treatment, or an impacted tooth or tumor. In ankylotic root resorption, there is no known stimulation factor; thus, no predictable treatment can be suggested. Therefore, various types of root resorptions can be classified according to the stimulation factors: pulpal infection resorption, periodontal infection resorption, orthodontic pressure resorption, impacted tooth or tumor pressure resorption, and ankylotic resorption.
