Spiral CT diagnosis and endodontic management of an anatomically variant palatal root with two canals in a maxillary first molar

Abstract

This case report presents the endodontic management of an anatomically variant palatal root with 2 canals (Vertucci type II) in a maxillary first molar, which was confirmed with the help of spiral computed tomography (SCT). This serves to remind clinicians that such anatomic variations should be taken into account during the endodontic treatment of maxillary molars and highlights the invaluable aid of the SCT in accurate diagnosis and in negotiating the complex morphologic variations in root canals, thus enabling successful endodontic management.

Root Canal Morphology;

“…Two or more radiographs are mandatory for assessment, currently spiral computed tomography (SCT), being used for treatment & designing for dental implants, it is better than staining and clearing technique in root canal structure & morphologic studies. [19][20][21][22][23] This study has undertaken for revealing the morphology of mandibular third molars to provide the better understanding to dentist to look forward when these teeth treating endodontically.…”

Endodontic Management of a Maxillary First Molar with Two Palatal Canals and a Single Buccal Canal: A Case Report

“…Since, it cannot be useful in cases with complex root canal anatomy, it is crucial to use all of the armamentaria to diagnose and treat the entire root canal system [10]. According to previous studies [1, 2, 4, 8] where computerized tomography (CT) was used for definitive diagnosis of morphologic abnormalities in the root canal anatomy, CBCT of the involved tooth was conducted in the present case.…”

“…Failures to detect aberrant root canals and to identify extra roots are one of the main causes for failure in the endodontic therapy [1]. Human molars demonstrate relatively high anatomic variations and abnormalities with respect to number of roots and root canals.…”

Two Canals in Maxillary First Molar: A Rare Dental Entity

“…6 After confirmation of this unusual morphology by spiral computerized tomography, incidentally they mentioned that the other maxillary first molar in their reported patient had also a similar morphology, but it had only one buccal canal in its single buccal root. 6,7 Radiographs produce only a 2-dimensional image, resulting in superimposition and distortion. Since it cannot be useful in cases with complex root canal anatomy, it is crucial to use all of the armamentaria to diagnose and treat the entire root canal system.…”

“…8,9 According to previous studies. 7 where Computerized Tomography (CT) was used for definitive diagnosis of morphologic abnormalities in the root canal anatomy. 10 spiral CT of the involved tooth was conducted in the present case.…”
