Management of a maxillary first molar having atypical anatomy of two roots diagnosed using cone beam computed tomography

Abstract

Most often, a clinician working on maxillary first molar when anticipates an aberration thinks of an extra canal but rarely does he preempt fewer canals. Maxillary first molar is a tooth, which has been extensively reviewed with respect to its external and internal morphology. Abundant literature related to its anatomy is available, but reports on incidence of two roots and two root canals in maxillary first molar are very limited. Here, a case of maxillary first molar is presented that had two roots: one palatal root with Type I canal configuration and one bulbous fused buccal root with Type V canal configuration; a unique root and canal configuration not seen in any of the earlier reported cases. Diagnosis of root canal aberrancy and subsequently, accurate management of the tooth was greatly facilitated by cone beam computed tomography (CBCT) scan. The relevance of CBCT in improving treatment prognosis is greatly emphasized in this report.

Endodontic management of a maxillary first molar with two roots and iatrogenic perforation diagnosed with the aid of cone beam computed tomography

“…This might have happened in embryologic stage, when the epithelium is not developed completely, the inadequate Hertwig sheath may have cause the fusion of roots. 15,16 Iatrogenic perforation can occur if the operator becomes disorientated while trying to locate canal orifices. Perforation repair can be technically challenging.…”

Cone-Beam Computed Tomography (CBCT) Analysis of an Unusual Configuration of the Upper First Molar With a C-shaped Canal With Apically Fused Roots: A Case Report

“…The root canal structure of the tooth can be fully understood through the use of cone-beam computed tomography (CBCT) systems, three-dimensional (3D) reconstructions, and spiral computed tomography [6][7][8]. The first molar with a C-shaped incidence was 1.1%, and the second molar prevalence was 3.8% globally [9]. This case study shows an uncommon root canal architecture of the first molar in the maxillary arch with apically joined roots and C-shaped canal morphology.…”

Endodontic management of a maxillary first molar with seven root canal systems evaluated using cone-beam computed tomography scanning

“…Sometimes, the number of canals vary, second mesiobuccal canal being the most common variation, between 18% and 96.1%. [ 1 2 ] Studies have shown the occurrence of third mesiobuccal canal to be in between 1.3% and 0.1%. [ 3 4 ] However, Lee et al .…”
