“…[ 1 2 14 ] With the introduction of the DOM and 3D imaging, the fin and confluent configurations were also identified. [ 33 34 35 ] Hence, in contemporary studies, a greater prevalence of the confluent configuration compared to fin and independent configurations has been reported. [ 9 33 34 35 ]…”

“…Sherwani et al . [ 35 ] observed that, in 67% of cases from an Indian population, the MMC orifice was located in the middle of the MB and ML orifice and 20% had the orifice closer to the ML canal, while the remaining 12% had the orifices located closer to the MB canal.

Objectives:The purpose of this paper is to systematically review the various studies and case reports on the morphology and prevalence of middle canals in the mandibular molars.Methodology:Electronic databases such as MEDLINE, PubMed, EBSCOhost, ScienceDirect and various journals were screened to identify published literature till March 2017 and earlier for articles related to middle canals in the human permanent mandibular molars. Obtained articles were categorized as original researches, case reports and review articles. Well-defined review questions were developed using the patient population, intervention, comparison and outcome framework to summarize the objectives: “Does middle canal vary in morphology and anatomic location? What is the prevalence of middle canals in mandibular molars? Does ethnicity affect the prevalence of middle canals in mandibular molars?” Morphology was studied and prevalence rates were determined from the evaluation of data extracted from the articles.Results:The search strategy resulted in 87 articles, of which 36 were original research papers and 51 were case reports. The prevalence of middle canals in the various populations ranged from 0.26% to 53.8%. Middle canals were reported in Europeans, Asians, Africans and South and North American populations. The prevalence of middle mesial canal and middle distal canal in various races was reported as up to 53.8% and 10%, respectively. The orifice of middle canal exists below a dentinal projection in the groove between the two main canals. They were observed in fin, confluent and independent configuration. Out of these, confluent configuration was more prevalent.Conclusion:Middle canal varies in morphology and anatomic location. Ethnicity affects the prevalence of middle canals in the mandibular molars.

“…Karapinar-Kazandag et al reported a higher number of additional mesial canals located closer to the mesiolingual canal in their study [17]. In a study evaluating the frequency of middle mesial canals in a North Indian population, the authors found that among 258 mandibular first molars, in 67% of the cases the mid-mesial canal orifice was located in the middle of the mesiobuccal and mesiolingual canal orifices, 20% had the orifice closer to the mesiolingual canal, while the remaining 12% had the orifices located closer to the mesiobuccal canal [19]. Differences in observation by various authors may be attributed to difference in study methodology, population studied, and number of teeth included in the study.…”

The objective of dentists is to preserve teeth affected by either caries, trauma, or any other pathological condition. Teeth with deep carious lesions often require endodontic treatment to preserve their form and function. Sound knowledge of root canal anatomy, endodontic pathology, and proper treatment protocol are vital in endodontic treatment success. Currently, there has been an ongoing trend of case reports that highlight the presence of extra canals, which in turn, cautions the clinician to be more prudent. Any missed canal during root canal therapy is the common cause of treatment failure. This case report emphasizes the fact that proper understanding of pulp anatomy combined with the use of modern diagnostic aids and proper treatment protocol is essential for treatment success. This case report describes successful management of three rooted mandibular first molar with extra canals.

“…Higher prevalence of MMC in mandibular first molars with two distal canals (45.4%) than the ones with one distal canal (13.7%). MMC was located in the middle of MB/ML orifices in 67% of cases from an Indian population and 20% had the orifice closer to the ML canal and 12% had the orifices located closer to the MB canal [11] .…”

The primary objective of endodontic therapy is to achieve a three-dimensional obturation of the root canal space to remove the tissue debris, microorganisms and their by products after a proper biomechanical preparation of the pulp chambers. The missing canal of complex root canal morphology is major reason for endodontic failure. The use of magnification, illumination, recent advancements, diagnostic aids and techniques help in minimizing the incidence of missing a canal. This case report describes the rare management of a left mandibular first permanent molar requiring root canal treatment with an additional Middle Mesial Canal (MMC) in the mesial root. Clinicians experience and approach is a key factor in negotiation and management of these aberrant canal configurations. Case Report and Review of Literature
