Abstract

Morphological variations can occur in primary and permanent teeth. Genetic and environmental factors could be responsible for various dental anomalies. Anomalous teeth are usually asymptomatic and are diagnosed during routine oral examination. These anomalies may increase caries susceptibility and complicate dental treatment procedures such as extraction or root canal treatment. We report a rare case of mandibular first molar with a single root and a root canal.

摘要

乳牙和恒牙均可出现形态变异。遗传和环境因素可能导致各种牙齿异常。异常牙齿通常无症状，在常规口腔检查时被诊断出来。这些异常可能会增加患龋易感性，并使拔牙或根管治疗等牙科治疗程序复杂化。我们报告一例罕见的下颌第一磨牙单根单根管病例。
