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.

“…(6)(7)(8)11,12) Transparency procedures and radiography were the most common methods; the limitations of these methods in the field of diagnosis have been mentioned in these articles. (12)(13)(14)(15)(16)(17) Other methods include decalcification, histologic evaluation, stereomicroscopic analysis, scanning electron microscopy (SEM), micro CT, and CBCT (11)(12)(13)18,19) with different results. The prevalence of the MM canal has been reported to be 0.82% to 37.5%.…”

“…[6] CBCT is primarily utilized in pre-treatment clinical contexts, making it an valuable technique for establishing the presence of isthmuses and MM canals in areas of operative interest. Chavda and Garg proved that CBCT's detection accuracy of MM is not inferior to magnification and troughing in an in vitro study [24].…”

Background: While there is ample research into the anatomy of mandibular molars, little is known regarding isthmuses and middle mesial (MM) canals in Chinese populations. The goal of this study was to determine the prevalence of MM canals and isthmuses in the mesial root of mandibular first molars using Cone-beam Computed Tomography. Methods: Cone-beam Computed Tomography images of 357 mature mandibular first molars were retrospectively analyzed. Presence of isthmuses and MM canals, and the length of isthmuses in the mesial root were recorded. Meanwhile, we also recorded possible correlated factors such as demographics, side of mandible, presence of separated distal-lingual roots. Results: Of these 357 teeth, 209 showed evidence of either complete or partial communication in the mesial root. Of these, 11(3.08%) exhibited true MM canals while 198(55.46%) exhibited isthmuses. Sex or side of mandible was not correlated with the prevalence of communication (isthmuses or MM canals) (P> 0.05). However, there was a significant association between the presence of a distal-lingual root and the prevalence of such communication (P< 0.05). The average length of isthmuses was 4.3 ± 3.1mm. Conclusions: We detected high rate of isthmuses and low rate of MM canals in mesial roots of mandibular first molars, which is important as such areas should be identified and cleaned during root canal treatment.
