Endodontic Treatment of Bilateral Maxillary First Premolars with Three Roots Using CBCT: A Case Report

Abstract

One of the determining factors for the success of endodontic therapy is understanding the morphological anatomy of the tooth structure and its variants in relation to its template anatomy. The internal anatomy of maxillary first premolars is particularly complex due to their variation in number of roots and canal configuration. However, the bilateral presence of three roots in a maxillary first premolar is of rare occurrence. This case report describes the unusual anatomy bilaterally detected in maxillary first premolars using Cone-Beam Computed Tomography.

Methodology for Morphometric Analysis of Modern Human Contralateral Premolars

“…Despite the lack of studies on the expected anatomy in bilateral teeth, reports on bilateral symmetry of unexpected and aberrant root canal morphology have not been scant in the dental scientific literature [99][100][101][102][103][104][105][106][107][108][109]. However, most of these studies have been on single incidences of bilateral anomalies.…”

Root canal treatment of a maxillary first premolar with three roots

“…Advanced diagnostic tools like cone-beam computed tomography (CBCT) may give a more accurate picture of root canal morphology. [ 13 ] In this case, the preoperative X-ray itself was showing the presence of two buccal roots and one palatal root with separate canals in each root. Hence, advanced and costly diagnostic tools like CBCT were not employed in this case.…”

“…This helps in the identification of hidden orifices (White Line Test). Troughing should be carried out under magnification to prevent the unnecessary removal of the tooth structure and also helps identify the root canal orifices ( Gopal et al, 2014 ).…”
