The Role of CBCT in Detection of MB2 in Maxillary First Molars: A Review

Abstract

The permanent maxillary first molar is a tooth known for its complex and variable root canal anatomy. One of the most common causes of nonsurgical endodontic retreatment is the presence of a missed canal, which is often associated with persistent periapical pathology. Traditional two-dimensional radiographic imaging has limitations in accurately visualizing the intricate internal anatomy of teeth. In contrast, cone-beam computed tomography (CBCT) provides three-dimensional imaging that allows for a more precise evaluation of root canal configurations. A comprehensive literature search was conducted using PubMed, Google Scholar, and ResearchGate databases for studies published between 2006 and December 2024 to evaluate the role of cone-beam computed tomography (CBCT) in detecting the MB2 canal in maxillary first molars. Conclusion: CBCT is a valuable tool for detecting and mapping the mesiobuccal root canal system of the maxillary first molar. Its use can significantly enhance the accuracy of diagnosis and treatment planning, thereby improving the overall quality of root canal therapy.
