Abstract
Thorough knowledge of root canal morphology is essential for the endodontic therapy. There are rare variations in canal number and configuration in maxillary molars, which could affect treatment outcome. This paper presents the endodontic management of a maxillary first molar with two palatal canals in one root (Vertucci type IV) and a single buccal canal. In this paper cone-beam computed tomography was made to asses this morphology. This paper is intended to reinforce clinician's awareness of the rare morphology of root canals.
Highlights
A thorough knowledge of root canal morphology is an important aspect of root canal treatment
Since the radiographic image is a shadow and it is a 2-dimensional image, the best applicative method for precise clarification of the root canal morphology of a tooth is cone-beam computed tomography (CBCT) [5], it may not to be practical in all clinical situations. This technique offers significant advances in anatomical reconstruction of teeth before and after instrumentation and obturation. This case report describes nonsurgical therapy of an unusual permanent maxillary first molar with 3 canals: 2 separate palatal canals and one buccal canal, a morphology that has not been reported in published articles that we found in our search
The present case was the endodontic management of a maxillary first molar with two palatal canals in one root and one buccal root canal
Summary
A thorough knowledge of root canal morphology is an important aspect of root canal treatment. Baratto-Filho et al (2009) assessed internal morphology of maxillary first molars by 3 different methods [4] They found that second palatal canal prevalence in ex vivo assessment, 2.05%, in clinical assessment, 0.65%, and by cone-beam computed tomography, 4.55%. Since the radiographic image is a shadow and it is a 2-dimensional image, the best applicative method for precise clarification of the root canal morphology of a tooth is cone-beam computed tomography (CBCT) [5], it may not to be practical in all clinical situations. This technique offers significant advances in anatomical reconstruction of teeth before and after instrumentation and obturation. The root canal anatomy was confirmed with the help of spiral CT
