下颌切牙多为单根单管,加之所处位置关系,一般认为下颌前切牙的根管治疗术容易操作。但有资料表明下颌切牙的根管解剖形态较为复杂,变异较多,给牙髓和牙周病的治疗带来了很大困难。所以,掌握下颌切牙的形态对临床治疗具有指导性的意义。本研究系统地回顾了下颌切牙的研究方法和进展,并结合临床对下颌切牙的牙冠和牙根等外部形态以及髓腔和根管形态等内部结构进行了较全面的综述。根管治疗成功的关键是对髓腔解剖的理解和掌握,所以,充分掌握牙根和根管形态并了解可能存在的变异,才能更好地进行治疗。
Mandibular incisors and more for a single single tube, combined with the location of the relationship is generally believed that the mandibular incisor root canal treatment is easy to operate. However, there are data that mandibular incisor anatomy of the root canal is more complicated, more variation, to the pulp and periodontal disease treatment has brought great difficulties. Therefore, to grasp the shape of the mandibular incisors has instructive significance for clinical treatment. This study systematically reviewed the research methods and progress of mandibular incisors, combined with the clinical clinical application of external morphology such as the dental crown and root of the mandibular incisors, as well as the internal structure of the medullary canal and root canal morphology. The key to successful root canal therapy is the understanding and mastery of the anatomy of the medullary canal, so that it is better to have a good grasp of the root and root canal morphology and to understand the possible variations.
