“…In case of disagreement, a joint decision was taken by discussion. A total of seven articles were finally included in the review: one article described the use of dental-CT in vivo [28], and six described the use of CBCT both in in vivo and in ex vivo studies [22–27]. Data about study design, population, and device used are summarized in Table 1.…”

The aim of this paper was to review the literature about the use of computerized tomography to evaluate the presence and characteristics of the second mesiobuccal canal in the maxillary first molar. An electronic search was performed. Frequencies of the presence of second mesiobuccal canal and root anatomy characteristics were extracted from the selected studies. Pooled frequencies were calculated as weighted means. Seven articles were included. A second mesiobuccal canal was present in 59.32% of the teeth, and it was noncommunicating in 58.45% of teeth presenting the canal itself. The most common root canal morphology was single canal or two separated canals. The present paper showed that cone beam CT is a viable radiologic device for the evaluation of the mesiobuccal root of maxillary first molars. In fact, it was observed that the frequency of second mesiobuccal canal detection is similar to those presented by clinical studies or micro-CT evaluations.

“…Besides, Neelakantan et al (1) reported MB 2 in 44.1%; they used another type of CBCT system (3D Accuitomo, Japan). Rathi et al (38) evaluated the frequency of MB 2 by CT and reported its percentage as 57%, while Wasti et al (26) used tooth clearing technique and found the second mesiobuccal frequency in maxillary first molar as 52%. The obtained results of these two studies were lower than this study.…”

Background:The success of endodontic treatment depends on detection of all root canals so that they could be cleaned, shaped and obturated appropriately. To achieve this, it is essential to know root canals complexities such as the number of canals and types of each root canal, which are genetically determined. Besides, the highest failure rates occur in maxillary first molars. Objectives: Therefore, the aim of this study was to investigate the root and canal morphology of maxillary first molars in an Iranian population using cone-beam computed tomography (CBCT). Materials and Methods: In this study, images of 156 extracted maxillary first molars placed in the waxed blocks were produced using CBCT. Two professional investigators checked images by NNT software in New Tom 3G system. Axial view and cross section of 1 mm thickness were used. The number of roots, canals, each roots canal, MB 1 -MB 2 orifice distances and canal types of the Vertucci classification were recorded. Finally, data was analyzed using SPSS16 software. Results: We found 100% of cases with three separated roots, from which 69.23% had four canals including MB 2 and 30.77% with three canals. 71.3% of mesiobuccal roots were two canals of type two Vertucci and 28.7% type 4 with the mean distance value of 2.55 ± 0.57 mm between MB 1 and MB 2 orifice. Conclusions: Most extracted maxillary first molars were three rooted and four canals. CBCT has relatively high reproducibility and accuracy of distinguishing MB 2 canal.

“…Cone-beam computed tomography (CBCT) as well as spiral CT have been widely used in endodontics in recent years (Stechow et al 2003, Cimilli et al 2005, Nakata et al 2006, Leung 2010, Rathi et al 2010, Singla & Aggarwal 2010, Kaneko et al 2011, Patel et al 2011, Kim 2012. In dentistry, CBCT has been used more routinely than spiral CT due to its higher resolution (Fig.…”

Aetiology, incidence and morphology of the C‐shaped root canal system and its impact on clinical endodontics

et al. 2014

The C-shaped root canal constitutes an unusual root morphology that can be found primarily in mandibular second permanent molars. Due to the complexity of their structure, C-shaped root canal systems may complicate endodontic interventions. A thorough understanding of root canal morphology is therefore imperative for proper diagnosis and successful treatment. This review aims to summarize current knowledge regarding C-shaped roots and root canals, from basic morphology to advanced endodontic procedures. To this end, a systematic search was conducted using the MEDLINE, BIOSIS, Cochrane Library, EMBASE, Google Scholar, Web of Science, PLoS and BioMed Central databases, and many rarely cited articles were included. Furthermore, four interactive 3D models of extracted teeth are introduced that will allow for a better understanding of the complex C-shaped root canal morphology. In addition, the present publication includes an embedded best-practice video showing an exemplary root canal procedure on a tooth with a pronounced C-shaped root canal. The survey of this unusual structure concludes with a number of suggestions concerning future research efforts.
