Abstract

An infected human root canal system harbors harmful microbiota that needs to be eliminated by root canal therapy. But the human root canal system is known to have a complex anatomy. Hence, the knowledge of a possibly aberrant anatomy is deemed necessary before carrying out a root canal therapy. Usually, the maxillary second molars have three roots and three or four root canals (a second mesiobuccal canal as the fourth canal). The presence of a second palatal root and a second palatal root canal is very rare (1.4% incidence). Failure to locate and treat such aberrant external and internal anatomy results in a compromised root canal therapy. With the introduction of advanced imaging and visualization techniques such as cone beam computed tomography (CBCT) and dental operating microscopes, the variations in root anatomy have been successfully detected and treated. This case report describes the endodontic management of a second maxillary molar with two palatal roots and four separate canals, performed with the help of CBCT.

Highlights

Endodontic therapy is performed to eliminate viable bacteria and toxins from the human root canal system
Such untreated canals harbor harmful microorganisms that lead to failure of the root canal therapy
This article presents a case of a maxillary second molar with a second separate palatal root canal orifice and a second palatal root

Summary

Introduction

Endodontic therapy is performed to eliminate viable bacteria and toxins from the human root canal system. The first and second maxillary molars have three roots, namely, mesial, buccal, and palatal. In the first maxillary molars, the possibility of finding a second mesiobuccal canal in a single mesiobuccal root can range from 18-96% [2]. This article presents a case of a maxillary second molar with a second separate palatal root canal orifice and a second palatal root. The pain was exaggerated on eating hot or cold food items His past dental history revealed that a root canal therapy had been initiated by a private practitioner a week ago.
