The main objective of nonsurgical endodontic treatment is to eliminate micro-organisms from the root canal system. Adequate knowledge of the root canal morphology and its complexities is essential to render successful endodontic treatment. Variations in tooth form and morphology may be found in the form of anomalous cusps in the crown region or additional roots. In permanent molars, changes in the crown morphology may occur either in the form of an additional tooth (paramolar) or supernumerary cusp termed as "paramolar tubercle".
非手术根管治疗的主要目标是清除根管系统中的微生物。充分了解根管形态及其复杂性对于成功进行根管治疗至关重要。牙齿形态和结构的变异可能表现为冠部区域的异常牙尖或额外的牙根。在恒牙磨牙中,冠部形态的改变可能表现为额外牙(副磨牙)或称为“副磨牙结节”的额外牙尖。
