OBJECTIVE The purpose of this study was to determine the root canal anatomy of mandibular first premolar teeth in an Emirati subpopulation using a decalcification and clearing method. MATERIALS AND METHODS One hundred permanent mandibular first premolar teeth extracted for orthodontic purposes from an Emirati subpopulation from the United Arab Emirates were used for this study. They were subj...

The purpose of the investigation was to establish the exact number of root canals in the maxillary first permanent molar, their direction, type and relation, based upon a large number of random samples. Randomly chosen 443 maxillary first permanent molars (221 left and 222 right) were investigated with the aim to get more knowledge into the morpho­ logy of the endodontic space. One canal in the...

conclusions however, root and canal anatomies of third molar teeth are unknown, but studies focusing on third molar teeth have shown their possibility of treatment. results according to the study on 173 mandibular third molars, 92.4%, 4.6%, and 2.89% had two, one, and three roots, respectively. majority of them had two or three canals and most of mesial root canals were type 2; but in 179 maxil...

OBJECTIVES To compare the efficacy of Reciproc(®) (VDW GmbH) and ProFile(®) (Dentsply Maillefer) instruments at removing gutta-percha from straight and curved root canals ex vivo filled using the cold lateral condensation and GuttaMaster(®) (VDW GmbH) techniques. MATERIAL AND METHODS Forty mesial roots of mandibular molars with two curved canals and 80 single-rooted teeth with straight root c...

conclusions most extracted maxillary first molars were three rooted and four canals. cbct has relatively high reproducibility and accuracy of distinguishing mb2 canal. results we found 100% of cases with three separated roots, from which 69.23% had four canals including mb2 and 30.77% with three canals. 71.3% of mesiobuccal roots were two canals of type two vertucci and 28.7% type 4 with the me...

BACKGROUND AND AIMS A perfect endodontic treatment necessitates proper understanding of the morphology of canal and pulpal variations. This in vitro study was conducted to demonstrate the in-ternal anatomy of mandibular canine teeth in an Iranian population. MATERIALS AND METHODS The samples consisted of 100 extracted mandibular permanent canines. The roots of the teeth were molded in acrylic...

PURPOSE To investigate the prevalence of bifid and trifid mandibular canals using cone-beam computed tomography (CBCT) images, and to measure their length, diameter, and angle. MATERIALS AND METHODS CBCT images of 500 patients, involving 755 hemi-mandibles, were used for this study. The presence and type of bifid mandibular canal was evaluated according to a modified classification of Naitoh ...

objective: knowledge about the internal anatomy of the root canal and apical foramen is a critical prerequisite for root canal therapy and is necessary for the success of endodontic treatment. this study aimed to determine the distance of apical foramen from the anatomical apex and apical constriction, evaluate the deviation of apical foramen from the anatomical apex and specify the most common...
