Bottom Line: Posttreatment image revealed 3 independent canals in the buccal root obturated efficiently to the accepted lengths in all 3 canals.Our study describes a unique C-shaped variation of the root canal system in a maxillary first molar, involving the 3 buccal canals.In addition, our study highlights the usefulness of CBCT imaging for accurate diagnosis and management of this unusual canal morphology.

ABSTRACT
The aim of this study was to present a method for endodontic management of a maxillary first molar with unusual C-shaped morphology of the buccal root verified by cone-beam computed tomography (CBCT) images. This rare anatomical variation was confirmed using CBCT, and nonsurgical endodontic treatment was performed by meticulous evaluation of the pulpal floor. Posttreatment image revealed 3 independent canals in the buccal root obturated efficiently to the accepted lengths in all 3 canals. Our study describes a unique C-shaped variation of the root canal system in a maxillary first molar, involving the 3 buccal canals. In addition, our study highlights the usefulness of CBCT imaging for accurate diagnosis and management of this unusual canal morphology.

(a) Preoperative periapical radiograph of the maxillary left first molar; (b) One file was placed in the mesiobuccal area and one in the palatal canal. However, when digital image was acquired, the file seemed to be inserted between the mesiobuccal and distobuccal roots. Thus, we feared that the file closer to the distal might have resulted in a perforation (white arrow).

Mentions: A 26-year-old woman was referred from a private dental clinic to Wonkwang University Dental Hospital for root canal treatment of maxillary left first molar. The patient's medical history was noncontributory. Medical history revealed spontaneous pain on the upper left side of her face for the past several days. Clinical examination showed a large distal temporary restoration and tenderness to percussion on the maxillary left first molar. Diagnostic radiograph showed the presence of subgingival caries in the distal area of the tooth (Figure 1a). On the basis of clinical and radiographic examination, the patient's condition was diagnosed as pulp necrosis with acute apical periodontitis and endodontic treatment was recommended.
