“…The layer of dentin in this groove is lighter in color than adjacent dentin. Studies have reported the average length of the groove in mandibular first and second molars to be 1.07–2.81 mm[ 36 ] and the average depth to be 1.05 mm[ 52 ] and 0.17–7.66 mm. [ 36 ] The difference in the observations between studies may be attributed to differences in the method of study, sample sizes and populations studied.…”

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.

“…The most common reason for endodontic failure is infection that extends along the root canal system into the apical area [ 5 ]. Special attention should be paid to unfilled canal(s), because they are the least resistant path to leakage or reinfection [ 1 , 15 , 30 ].…”

“…However, only by correct clinical examination and interpretation of these images can the clinician detect variations and be aware of them before and during endodontic procedures [ 32 , 38 ]. Clearly, third mesial and distal canals in mandibular molars should be investigated and identified when planning root canal therapy [ 30 , 39 , 40 ]. The mesial and distal grooves of mandibular molars should be explored and cleaned.…”

“…In addition, the most cases [9–15] were identified by periapical radiographs, which have limitations in describing 3-dimensional (3D) roots and root canal anatomy. Thus, this case report describes the endodontic management of three independent mesial canals in a first mandibular molar where cone beam computed tomography (CBCT) was used at the 4-year followup.…”

Endodontic treatment of mandibular molars is challenging because of variable root canal morphology. The nonsurgical endodontic management of a mandibular first molar presenting an independent middle mesial canal is reported. After coronal access, additional clinical inspection of the mesial canals' orifices and their interconnecting groove using an endodontic explorer and 4.5× loupes enabled the identification of the middle mesial canal orifice. All root canals were chemomechanically prepared and filled. The tooth was asymptomatic and functional after 4 years of followup. Cone beam computed tomography (CBCT) images revealed normal periapical status and three-dimensional (3D) anatomical aspects of the root canal system.
