OBJECTIVE The aim of this study was to evaluate the anatomy of the nasopalatine canal in a Lebanese population using cone-beam computed tomography (CBCT) technology. MATERIALS AND METHODS CBCT images of 63 Lebanese adult patients were included in this study. The length, shape, diameter of the oral opening corresponding to the incisive foramen and inclination in relation to the hard palate of ...

This study aimed to describe the morphometric relationship of root canal orifices on pulp floor in presence/absence mesiobuccal second (MB2) maxillary first molars and other aspects its internal anatomy. Sixty-two were scanned by micro-CT. The presence MB2 was verified. distance between center points MB1, MB2, distobuccal (DB), palatal (P) measured (MB1-MB2, MB1-DB, MB2-DB, MB1-P, DB-P). MB1-P ...

i ntroduction: the aim of this study was to compare the shaping ability of two single-file systems and conventional rotary instruments in severely curved root canals of extracted human molars. methods and materials: mesiobuccal canals of 120 mandibular molars with angles of curvature ranging between 25 ° and 35 ° and radii of curvature from 5 to 9 mm, were divided into three groups ( n =40). in...

CONTEXT AND AIMS The purpose of this study was to compare and evaluate the shaping ability of ProTaper (PT) and Self-Adjusting File (SAF) system using cone-beam computed tomography (CBCT) to assess their performance in oval-shaped root canals. MATERIALS AND METHODS Sixty-two mandibular premolars with single oval canals were divided into two experimental groups (n = 31) according to the system...

INTRODUCTION The aim of the present study was to comparatively evaluate the physical surface changes and incidence of separation in rotary nickel-titanium (NiTi) instruments using scanning electron microscope (SEM). METHODS AND MATERIALS A total number of 210 freshly extracted human maxillary and mandibular first molars were selected and distributed between three groups. Three different syste...
