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.

“…[ 15 ] Goel et al reported that 60% of the mesial root of permanent mandibular first molars presented two foramina (Vertucci Type IV), whereas 6.7 and 3.3% of these molars had three (Vertucci Type VIII) and four foramina (Sert and Bayirli Type XX), respectively. [ 16 ] Few researchers[ 6 7 17 ] reported the presence of six canals in mandibular first molars, but none of these reported contralateral molars with diverse morphologies.…”

Endodontic management of contralateral mandibular first molars with six root canals

et al. 2017

View full text Add to dashboard Cite

The knowledge of variations in root canal morphology is essential for a successful endodontic outcome. Contralateral mandibular molar with six root canals is a rare entity. Root canal treatment of mandibular molars with aberrant canal configuration can be diagnostically and technically challenging. While dealing with variant mandibular molars, mishaps may happen. This case report describes variations in contralateral mandibular molars and also an endodontic mishap while managing them.

“…Literature demonstrates the existence of mandibular first molars with six root canals in which the mesial root encases two, three, or four canals, and the distal root encases four, three, or two canals, respectively ( 5 - 17 ) ( Table 1 ). Such accessory root canals can often join nearby main canals, and only two reports documented the occurrence of six-canalled mandibular first molar, in which all canals have separate foramina ( 8 , 14 ). Six canals have also been reported in three- and four-rooted mandibular first molars ( 15 , 18 ).…”
