“…In the present study, there was no correlation between gender and the presence of MB2. This result is in agreement with those of Reis et al 32 Al‑Nazhan 25 and Zhang et al 34 In contrast, MB2 was shown to be predominant in males, as also reported by Al-Shehri et al 26 Faraj, 38 Ratanajirasut et al 39 and Kim et al 35 who found a relationship between gender and the number of canals. We also found no relationship between age and prevalence of MB2 canals.…”

The aims of this study were to assess the prevalence and configuration of the second mesiobuccal (MB2) canal in the mesiobuccal MB root of permanent maxillary first molars at different root levels in a Saudi sub-population using cone-beam computed tomography (CBCT) and to measure the inter-orifice distance between MB & MB2 at the pulpal floor level. Materials and Methods: This retrospective study was carried out on CBCT images of Saudi patients seen at King Abdul Aziz University. A total of 106 maxillary first molars were evaluated using a specialized software program (iCAT CBCT software). The prevalence of MB2, canal configuration and location of joining (apical-middle-coronal), if present was calculated. Also, the inter-orifice distance between both canals was measured at the level of the pulpal floor. Chi-square and one-way analysis of variance (ANOVA) were used. Results: The MB2 canal was found in 92 (86.8%) maxillary first molar teeth. The MB and MB2 canals were joined in 61 (58%) cases, where the location of joining was 14 (23%), 17 (27%), and 31 (50%) in the coronal, middle, and apical third, respectively. The mean interorifice distance between both canals at the level of the pulpal floor was 2.52±0.76 mm. Conclusion: The prevalence of MB2 canal in this Saudi sub-population was high. The prevalence decreased as the root canal approached the apical third. There was no correlation between the average distance and occurrence of canal joining. CBCT is useful in detecting and mapping the mesiobuccal root canal system, with a likelihood of enhancing the quality of root canal treatment.

“…In a study performed by Martins et al looking at the worldwide prevalence of MB2 canals using CBCT, the overall prevalence was 73.8% [ 68 ]. Bentancourt P et al found 69.82% of MB2 canals in their study on 1100 maxillary molars using CBCT [ 69 ]. Even though the CBCT specifications changed across the studies, the Newtom CBCT scanner was the most commonly used scanner.…”

The aim of this paper is to review the literature on root canal configuration (RCC) and the frequency of occurrence of a second mesiobuccal canal (MB) in human permanent maxillary first molars where cone-beam computed tomography (CBCT) is used. Online electronic databases such as PubMed-Medline, Embase, Scopus and Cochrane Library were searched using appropriate keywords from the earliest available date until 12th June 2022, without restriction on language. In the mesiobuccal root, type I was the most frequent (33.29%), followed by types II and IV (27.18% and 26.36%, respectively). Moreover, 68.2% of maxillary first molars had a second MB canal. For both the distobuccal and palatal roots, type I was the most prevalent, with 99.08% and 97.83% occurrence, respectively. All other types were infrequent. Type I RCC is most frequent in all the roots of the maxillary first molars. Hence, care must be taken during biomechanical preparation of the MB roots.

“…The MB 2 canal was found in 53.78% of the cases that means it was present in approximately half of the cases. 19 Another study on first maxillary molar teeth exhibited the highest prevalence of MB 2 canal, 92% and 87%, for right maxillary first molar and left maxillary first molar, respectively when CBCT was used. 20 In another retrospective study of 100 Dental CT, presence of MB 2 canal in maxillary molars were present in 57%.…”

Background: Permanent maxillary first molar normally has three root canals but it can have extra root canals for which several studies were done in many parts of the globe. However, this type of study to explore extra canal is lagging in the context of Nepal. Objectives: The objective was to determine the percentage of extra canal in permanent maxillary first molar in patients undergoing root canal treatment and to compare the same between male and female. Methods: The descriptive cross-sectional study was conducted in the department of conservative dentistry and endodontics of People’s Dental College and Hospital from 20th December 2019 to 20th December 2020 after receiving ethical approval from Nepal Health Research Council on 18th December 2019 (ERB protocol No 888/2019) . One hundred and eighty permanent maxillary first molar teeth without root canal calcification were enrolled. Convenient sampling was done. Access opening was done and all canal orifices were located and recorded. Data were analyzed using Statistical Package for the Social Sciences (SPSS) version 22.0 with frequency table. Chi-square test was used for inferential statistics. Results: Out of 180 teeth, extra canals were present in 44(24.4%) having more numbers in male than in females. Extra canal was present in the mesiobuccal root. Conclusion: Extra canal in the permanent maxillary first molar is present in Nepalese population with greater number in male than in female. Thus, exploration of the pulp chamber in search of an extra canal is necessary to prevent failure of root canal treatment.
