Rare Variation in Root Canals of Mandibular, Canine and Premolar Teeth

One of the main causes of failure of root canal treatment is failure to diagnose variations in root canal anatomy. Hence, diagnosing the correct root canal morphology is critical for successful endodontic treatment. The purpose of this article is to discuss variations seen in root canal morphology of mandibular canine and first premolars. In the present case two separate canals along with separate roots in mandibular canine and premolar were identified and successfully managed. INTRODUCTION The success of root canal therapy depends upon a thorough knowledge of the root and anticipation for their possible morphologic variations is essential. The wide range of studies conducted on root canal morphology, from the early work of Hess and Zurcherl to various recent authors2, demonstrating anatomic complexities of the root canal systems, have all emphasized on the fact that a root with tapering canal and a single foramen is an exception rather than a rule. Root canal variation can be identified with intra oral peri apical (IOPA) radiograph, magnifying optical loupes, surgical operating microscopes, endodontic endoscopes and Cone Beam Computed Tomography (CBCT).3 This article describes endodontic management with morphological variations in anatomy of mandibular canine and premolar. CASE REPORT: An 18 year old female patient complained ofpain in lower left front tooth region since 45 months. Infra oral examination revealed presence of dental caries in relation to 33, 34. IOPA radiograph (Figurel) showed presence of two roots in left mandibular canine and premolar. IOPA radiographic examination also revealed pulp involvement with two roots in right Figure 1: IOPA showing presence of two roots in left mandibular canine and premolar.

Diagnosis was chronic irreversible pulpits. Tooth isolation was done with rubber dam. 2%
