Root canal therapy of a maxillary first molar with five root canals: case report

Abstract

This paper reports the case of a maxillary left first molar that presented three root canals in the mesiobuccal root. Root canal therapy and case management are described. Features like wide crown access, adequate illumination and use of exploring files where important for successful completion of the endodontic treatment.

Endodontic treatment of a maxillary first molar having three mesiobuccal canals with the aid of spiral computed tomography: a case report

“…This information is summarized in Table 1. This case report presents an unusual case of a maxillary first molar with three mesiobuccal canals (two lingual-most canals appeared to join at the middle third) similar to the case reports of David B. Ferguson and Amauri Favieri et al in which two lingual most canals appeared to join at the apical third (13,14). Adanir also reported a similar case with four roots and six canals (8).…”

Analysis of the Internal Anatomy of Maxillary First Molars by Using Different Methods

“…Martinez-Berna and Ruiz-Badanelli (5) reported 3 cases in which the maxillary first molars had presented 6 root canals (3 in MB, 2 in distobuccal [DB], and 1 in palatine root). Favieri et al (1) also showed a similar occurrence in the MB root and reported the difficulty of handling such cases. The occurrence of 2 canals in DB roots has been less frequent and has been reported in 3.6% of maxillary molars (4).…”

“…The several anatomic variations that might exist in the root canal system have contributed to endodontic treatment failures (1). Maxillary first molars have exhibited a frequent radicular anatomy of 3 roots and 3 or 4 canals (2).…”

WaveOne: A Simple and Safe Way to Perform an Endodontic Treatment

“…Variations in the root canal's anatomy of the root canals play an important role on endodontic therapy success (Chakradhar Raju et al, 2010), mainly in teeth with pulp necrosis (Favieri et al, 2006). It is very important to point out the changes in the root canals morphology in teeth requiring endodontic treatment (Oporto et al, 2010).…”
