Objective: To evaluate root canal configuration and morphology of premolar teeth among Saudi subpopulations using cone beam computed tomography (CBCT). Material Methods: In this retrospective cross-sectional study, CBCT images 314 patients comprising 346 maxillary 412 mandibular first (FPM) teeth, 298 387 second (SPM) were analyzed to the number roots, morphology, based on Vertucci's classifica...

Introduction: A thorough understanding of root canal anatomy and morphology is required for achieving high levels of success in endodontic treatment. The possible anatomic configurations of premolars are well documented in the literature, except for the small incidence of bilateral multi-rooted maxillary and mandibular premolars with three canals. Objective: To report a rare case of bilateral m...

Objective: To determine whether the missing canals in endodontically treated single-rooted teeth with two-canals are present either buccal or lingual/palatal for Turkish subpopulation. Methods: High-quality cone-beam computed tomography scans of 1297 belonging to 782 adults over age 18 were obtained from archive a dental clinic. Within this dataset, 129 had undergone endodontic treatment and po...

the most difficult clinical considertions in orthograde root canal treatment are generally related to the anatomy of the teeth. three-canalled maxillary and mandibular premolars (mini-molars) have been reported in several studies. the purpose of this paper was to review various aspects of three-canalled premolars including incidence, clinical and radiographic diagnosis, racial predisposition, a...

The possibility of bilateral maxillary second premolars having three separate roots is quite low; however, it must be taken into account in clinical and radiographic evaluations during endodontic treatment. A correct clinical and radiographic diagnosis based on knowledge of root canal anatomy and critical interpretation of radiographs is necessary for a safer and successful endodontic treatment...

INTRODUCTION Sound knowledge of the external and internal morphology of the different teeth groups is essential to ensure a successful outcome of root canal treatment. The aims of this study were to review the available literature with respect to the root and root canal morphology of maxillary first premolars and discuss the clinical considerations of this morphology on the various dental proce...
