Root and Root Canal Morphology and Its Variation of the Human Mandibular Canine: A Literature Review

Abstract

The objective was to review the literature of the root and root canal morphology of the human Mandibular canine. Published studies cite the anatomy and morphology of the mandibular canine tooth. Individual case reports of anomalies were included to demonstrate the extreme range of variation. Almost all of the teeth in the anatomic studies were single rooted (94.8 %). The incidence of two roots (5.2 %) was extremely rare. Anatomic studies of the internal canal morphology found that a single canal was present in 89.4 % of the teeth, while 10.6 % of the teeth had two or more canals. However, the root and root canal morphology of the mandibular canine can be extremely complex and requires careful assessment. As an Endodontist, one should be aware of all the probable nooks and crannies of the complex root canal, its protean permutations, and combinations, to render the finest possible treatment. As is the case with any other treatment, endodontic therapy; if performed in the properly delineated and precise manner spells more than 99 % success rate. This review article attempts to bring out the possible nuances of the complex root canal system and various methods of reckoning with these significantly essential details.

“…Ignorance of internal tooth anatomy leads to the failure of endodontic treatment because of lack of proper cleansing and sealing. [ 7 ] Many of the problems encountered during endodontic treatment occur because of an inadequate understanding of the pulp space anatomy of the teeth. The precise identification of the internal anatomy is the primary step in root canal treatment.…”
