The Endodontic Treatment of Three-Rooted Maxillary Premolar Resembling a Small Molar: A Case Report.

An appropriate access cavity, sufficient cleaning, proper shape, and full obturation are necessary for a root canal to be successful. In the earliest stages of therapy, the location of all root canals within the tooth is crucial. Even if the morphology of most teeth is normal, some variations should be acknowledged. As a transitional tooth between incisors and molars, the maxillary first bicuspid is most frequently two-rooted, while it can also occasionally show as a three-rooted system. While it often has two canals, it can occasionally have three, and it is quite easy to overlook the third canal.
