Permanent mandibular central incisor is rarely affected by tooth shape anomalies of crown and root. Co-occurrence of multiple anomalies in a permanent mandibular central incisor is extremely rare. This paper reports an unusual concurrent combination of multiple dental anomalies affecting both the crown and root of a permanent mandibular left central incisor - talon cusp, dens invaginatus, short root anomaly and macrodontia -, which has not previously been reported together. Case management is described and implications are discussed. The dentist should be aware of these rare entities in order to provide an accurate diagnosis and management for which detailed examination of the tooth both clinically and radiographically is very important.
恒牙下颌中切牙很少受到冠部和根部牙齿形态异常的影响。恒牙下颌中切牙同时出现多种异常的情况极为罕见。本文报告了一例罕见的同时累及恒牙下颌左中切牙冠部和根部的多种牙齿异常组合——畸形中央尖、牙内陷、短根异常和巨牙症——此前尚未有这些异常同时出现的报道。文中描述了病例处理过程并讨论了相关影响。牙医应了解这些罕见情况，以便进行准确的诊断和处理，为此，对牙齿进行详细的临床和影像学检查非常重要。
