Abstract

During orthodontic treatment, root resorption can occur unexplainably. No clear distinction has been made between resorption located within specific regions and resorption occurring generally in the dentition. The purpose is to present cases with idiopathic (of unknown origin) root resorption occurring regionally. Two cases of female patients, 26 and 28 years old, referred with aggressive root resorption were investigated clinically and radiographically. Anamnestic information revealed severe virus diseases during childhood, meningitis in one case and whooping cough in the other. One of the patients was treated with dental implants. Virus spreading along nerve paths is a possible explanation for the unexpected resorptions. In both cases, the resorptions began cervically. The extent of the resorption processes in the dentition followed the virus infected nerve paths and the resorption process stopped when reaching regions that were innervated differently and not infected by virus. In one case, histological examination revealed multinuclear dentinoclasts. The pattern of resorption in the two cases indicates that innervation is a factor, which under normal conditions may protect the root surface against resorption. Therefore, the normal nerve pattern is important for diagnostics and for predicting the course of severe unexpected root resorption.

摘要

在正畸治疗期间,牙根吸收可能会莫名发生。位于特定区域的吸收与牙列中普遍发生的吸收之间尚无明确区分。目的是呈现局部发生特发性(病因不明)牙根吸收的病例。对两名分别为26岁和28岁、因侵袭性牙根吸收前来就诊的女性患者进行了临床和影像学检查。既往史信息显示,两名患者童年时期均患过严重病毒疾病,其中一例患脑膜炎,另一例患百日咳。其中一名患者接受了牙种植治疗。病毒沿神经路径传播可能是意外吸收的一个解释。在这两个病例中,吸收均始于颈部。牙列中吸收过程的范围遵循病毒感染的神经路径,当到达神经支配不同且未被病毒感染的区域时,吸收过程停止。在一例病例中,组织学检查发现了多核破牙本质细胞。这两个病例中的吸收模式表明,神经支配是一个因素,在正常情况下可能保护牙根表面免受吸收。因此,正常的神经模式对于诊断和预测严重意外牙根吸收的进程很重要。
