Root Canal Morphology of the Mesiobuccal Root of Maxillary First Molars: CBCT Study

Objective: Understanding tooth anatomy is crucial for effective endodontic treatment. This study investigated the roots and root canal morphologyof the mesiobuccal root of the maxillary first molars using cone-beam computed tomographic (CBCT) imaging. Methods: A total of 18 teeth with intact roots were collected.Mesiobuccal [MB] root was sectioned completely with diamond discsandMB2canals was located using size 10file and the orifice was enlarged using slow speed hand piece and bur. Results: Overall 44% of tooth had type 2vertucci classification, 33.3% of tooth had type 4 Vertucci classification and 11.1% of tooth had type 1 and 6 vertucci classification. Conclusion: Incidence of MB2 canals was 88.9%.Outof 18 teeth with intact roots,16 teeth had MB2 canals.Type IIVertucci classification was seen in most of the teeth, where MB2 canals were present.
