Abstract：The root canal anatomical structure of the maxillary first molar is relatively complex.Clinically,more attention is often paid to the root canal variations of the mesial buccal root,while the variations of the distal buccal root(DB)are often overlooked.Failure to fully identify,prepare,clean,and fill the additional root canals is one of the important factors leading to the failure of root canal treatment.This study reviews the existing in vivo and in vivo research methods on the anatomical characteristics of the distal buccal root of the maxillary first molar.It focuses on analyzing the influence of different methods(such as the transparent specimen method,Micro-CT,and Cone-Beam CT)on the detection rate of variations,and explores the possible causes of the differences in the detection rates as well as the classification characteristics of multiple root canals in the DB root.Advancements in the understanding of DB root morphology provide valuable insights into the anatomical complexity of the root canal system and offer guidance for enhancing radiographic evaluation and intraoperative exploration strategies,ultimately aiming to improve the success rate of root canal therapy.
