Abstract

The aim of the present clinical case report is to describe the singular root canal anatomy and endodontic management of a maxillary second molar with two palatal roots and two separate canal orifices. A 60 years-old female Hispanic/Latino patient attended the Endodontic Department at University of Buenos Aires School of Dentistry with acute pain in her maxillary left second molar. Clinical radiographs examination revealed unusual root morphology. Cleaning and shaping were completed with 5.25% NaOCl irrigation, 15% EDTA solution and hand/rotary instruments. Filling was performed with gutta-percha points and resin-based sealer. After one year follow-up periapical radiographs and CBCT images showed healing in the area and patient was asymptomatic.

Highlights

Presence of bacteria in the root canal system is a crucial dilemma in endodontics
There were some clinical case reports of maxillary second molars evidencing the presence of two palatal roots [7] [8]
In the present case report, the two palatal roots were not detected from the preoperative radiograph

Summary

Introduction

Presence of bacteria in the root canal system is a crucial dilemma in endodontics. This may affect the endodontic outcome stimulating periradicular tissue inflammation, reinforcing the theory that elimination of bacteria should be the most important goal in endodontics therapy [1]. Maxillary second molar has been described to have three roots and three or four canals, with the fourth canal located in the mesiobuccal root. Second maxillary molars with two palatal roots are rare. There were some clinical case reports of maxillary second molars evidencing the presence of two palatal roots [7] [8]. Christie et al [9] presented a classification in three types of maxillary teeth with two palatal root canals: Type I have two widely divergent palatal roots. The aim of the present clinical case report is to show the uncommon root canal anatomy of a Type II maxillary molar with two separated palatal roots and the endodontic management for this tooth
