Tooth 31 previously treated with symptomatic apical periodontitis. Missed palatal canal located and treated. Anterior teeth present significant challenges in treatment due to their narrow crown dimensions and the relatively high incidence of two canals, which is reported to range from 20-40%, depending on the study.1,2 Achieving adequate access often necessitates a lingual extension to avoid overlooking a second canal. However, the narrow morphology of these teeth increases the risk of procedural complications, with perforation being a common concern during treatment. Resources to Help AI technology offers additional tools to help with case selection. The AAE EndoCase app and the British Endodontic Society (BES) app enable dentists to complete a self-assessment prior to seeing a patient. An algorithm assigns a score consistent with the difficulty level and the dentist can manage or refer treatment based on their comfort level and experience. When we apply selection criteria to decision making, endodontic treatment is highly predictable and successful. References: 1. Almohaimede A, Alqahtani A, Alhatlani N, Alsaloom N, Alqahtani S.
