Abstract：As one of the important functional teeth in the oral cavity,the mandibular first permanent molar erupts early in the permanent dentition and is prone to caries.Because of the large number of mesial roots and the complex internal anatomy of root canal,it is often the most important part of root canal treatment.In clinical treatment,common anatomical structures such as root canal isthmus,middle mesial canal,curved root canal and danger zone are likely to lead to complications such as missing root canal,incomplete cleaning of root canal preparation,and step or lateral penetration,and there are large differences between individuals,which are related to many factors such as gender,age and race.In order to master the anatomical structure of mesial root of mandibular first permanent molar and improve the success rate of root canal treatment.In this paper,the anatomic features,related factors and clinical significance of mandibular permanent molar were reviewed,in order to provide reference for the treatment of mandibular first permanent molar.
