The Authors describe the clinical case in which a 30 years old male patient presents anomalous pigmentation of the oral mucosa after the endodontic treatment of the upper right central incisive. The mucosa's anomaly appeared at the height of the lower third of the root near the branch of an accessory endodontic canal previously filled and it was caused by the outlet of filling material. After the examination of this case, the Authors affirme the importance of an accurate anamnesis in order to obtain a correct diagnosis of the various kinds of pigmented lesions, distinguishing the etiology, the pathogenesis and the histologic patterns.
作者描述了一例临床病例，一名30岁男性患者在右上中切牙进行根管治疗后出现口腔黏膜异常色素沉着。黏膜异常出现在先前已充填的副根管分支附近牙根下三分之一高度处，是由充填材料溢出所致。在对该病例进行检查后，作者肯定了准确问诊对于正确诊断各类色素沉着病变的重要性，以区分其病因、发病机制和组织学模式。
