Selected articles were case reports or reviews of patients who had multiple root resorption with no systemic or local factors that may have contributed to root resorption, the resorption originating at the cemento-enamel junction of teeth and involving more than three teeth in the dentition.
Clinical, histological and historical findings are summarised for all identified patients.
Multiple idiopathic cervical root resorption (MICRR) was an incidental finding on routine clinical and radiographic examination. There appeared to be no correlation between this type of resorption and any medical or dental finding. Radiographically, MICRR was found to begin at the cemento-enamel junction and then either progress to involve the entire cervical region or, at some point, spontaneously arrest. Those cases that progressed to involve the entire cervical region required extraction. The number of teeth that demonstrated this condition ranged from five up to 24 per patient. More teeth became involved as the condition was followed in time. There was no detectable frequency of occurrence for any particular dental region or tooth among the involved teeth. Of a total of 18 patients, 13 were females whose ages ranged from 7 to 68 years of age. Ten of the 18 patients were Caucasian.
Multiple idiopathic cervical root resorption was found most frequently associated with younger females. This condition appeared to be of unknown aetiology and uncertain natural history.

入选的文章为病例报告或对患有多发性牙根吸收患者的综述,这些患者不存在可能导致牙根吸收的全身或局部因素,牙根吸收起始于牙骨质 - 釉质界,且累及牙列中的三颗以上牙齿。
总结所有已识别患者的临床、组织学和病史发现。
多发性特发性颈段牙根吸收(MICRR)是在常规临床和影像学检查中偶然发现的。这种类型的吸收与任何医学或牙科发现之间似乎没有相关性。在影像学上,发现MICRR始于牙骨质 - 釉质界,然后要么进展至累及整个颈段区域,要么在某个阶段自发停止。那些进展至累及整个颈段区域的病例需要拔牙。表现出这种情况的牙齿数量每位患者从五颗到二十四颗不等。随着时间推移,更多牙齿受累。在所累及的牙齿中,任何特定牙区或牙齿均未检测到发生频率。在总共18例患者中,13例为女性,年龄范围从7岁至68岁。18例患者中有10例为白种人。
多发性特发性颈段牙根吸收最常与年轻女性相关。这种情况的病因似乎不明,自然病史也不确定。
