Numerous terminologies have been employed in the dental literature to describe the roots and root canal systems of maxillary molars. This multiplicity in naming of roots and canals makes the reader susceptible to misinterpretation and confusion. No consensus thus far has been arrived at for defining the names of roots and root canals in maxillary molars, including their various morphological aberrations. The anatomical relation of roots and their root canals were identified and were subsequently named based on definite sets of criteria. A new method for identification and naming of roots and root canal anatomy in maxillary molars, based on their root and canal relationship, was formulated and is presented in this paper. The nomenclature makes certain essential modifications to the traditional approach to accommodate naming of the various aberrations presented in the maxillary molars. A simple, yet extensive, nomenclature system has been proposed that appropriately names the internal and external morphology of maxillary molars.
牙科文献中使用了众多术语来描述上颌磨牙的牙根和根管系统。牙根和根管命名的这种多样性使读者容易产生误解和混淆。迄今为止，对于上颌磨牙牙根和根管的命名，包括其各种形态变异，尚未达成共识。牙根及其根管的解剖关系已被确定，并随后根据明确的标准进行了命名。本文提出并介绍了一种基于上颌磨牙牙根与根管关系来识别和命名其牙根及根管解剖结构的新方法。该命名法对传统方法进行了某些必要的修改，以适应上颌磨牙出现的各种变异的命名。本文提出了一个简单但全面的命名系统，该系统对上颌磨牙的内部和外部形态进行了恰当的命名。
