Root canal treatment of Maxillary First Premolar with Three Roots: A case report.

This case report is for a rare case of root canal treatment of the permanent maxillary right first premolar presented with three roots and three canals (Vertucci Type VIII). The patient is a 67-yearold male with hypertension and is allergic to milk and hydrocodone. The affected tooth was diagnosed with necrotic pulp with symptomatic apical periodontitis during examination. Root canal treatment was carried out in this patient under rubber dam isolation, and cleaning and shaping were done with the help of ProTaper Gold rotary files. The obturation was done using a continuous wave compaction technique by the Calamus Dual Obturation System. The unusual anatomy of this case can occur in only 0.95-1.6% of cases. The difficulty in treating such cases is identifying the extra canal. Cone Beam Computed Tomography is the gold standard in finding such a canal. However, in this case, two periapical radiographs were taken to identify the extra root due to the absence of CBCT in the clinic. Using Cone Beam Computed Tomography, periapical radiographs with different angulations and magnification enhance visibility and improve the success rate in such cases. This comprehensive approach improves the accuracy of diagnosis and treatment outcomes in cases with complicated anatomy. [ABSTRACT FROM AUTHOR]
