It has been well known that mesiobuccal roots of maxillary molars tend to have more than 1 canals. 2nd mesiobuccal canals are in many cases calcified. So clinicians often have difficulty in finding these 2nd mesiobuccal canals. Moreover, the root canal morphology of mesiobuccal roots of maxillary molars is complex in many cases. To find and treat 2nd mesiobuccal canals, knowledge on incidence, type, and location of 2nd mesiobuccal canals is necessary. Use of Cone-Beam computed tomography (CBCT) is also helpful for finding 2nd mesiobuccal canals. And also, it is recommended to use proper illumination and magnification along with the use of instruments such as front surface mirror, long shank bur, and ultrasonic tips.
