Fig. 13 This angled postoperative image shows the high degree of curvature and the joining of the MB1 and MB2 canals in this root. Note: This tooth has not only been treated in a proper endodontic manner, it has also been treated in such a way as to allow a good final restoration, thereby ensuring long-term success. After an endodontic procedure has been completed, it is critically important to have the tooth restored properly and in a timely manner. Fig. 14 Fig. 15 Patient was seen for a one-year recall and the tooth was completely asymptomatic. The tooth was restored with a well-sealing coronal restoration. Note: The long-term prognosis of this tooth is excellent! Conclusion This case is an example of how a well-conceived treatment plan can facilitate performing endodontic therapy on a difficult tooth. Diagnostic radiology made it clear that this tooth had a severely curved mesial root. Consequently, special consideration was given to straight-line access and the achievement of such, when combined with the use of heat-treated files in the apical half of each canal, allowed instrumentation to reach the apex of all canals. Obturation was performed using a bioceramic sealer and, when combined with a bioceramic provisional, resulted in an excellent base for the final restoration. n 3D imaging of the final fill shows the high degree of curvature. Note: The challenging anatomy in the apical 5mm is addressed through proper access and using heat-treated files as " scouts " in this area.
