CUNHA, Rodrigo Sanches et al. The microsonics concept: maxillary first molar with five root canals - case report. RSBO (Online) [online]. 2011, vol.8, n.2, pp. 231-235. ISSN 1984-5685.

INTRODUCTION: The complex anatomy of the root canal system is a continuous challenge for endodontists. Permanent maxillary first molars may present several morphological variations, both in the number and location of roots and canals. Therefore, the success of the endodontic treatment depends on an accurate knowledge of root canal anatomy. OBJECTIVE AND CASE REPORT: This study describes the endodontic treatment of a permanent maxillary first molar diagnosed with irreversible pulpitis. The technology employed to evaluate the case, namely dental operating microscope associated with ultrasonic tips, was essential to delineate the anatomic characteristics of the tooth to be treated, revealing the presence of five root canals: two mesiobuccal, two distobuccal, and one palatal canal. CONCLUSION: The knowledge of the tooth anatomy, as well as its possible anatomic variations, combined with the use of current technologies, such as dental operating microscope, ultrasonic tips, and computed tomography, help to enhance the endodontic treatment success.
