Understanding the morphology of the root canal plays a key role in the success of a root canal therapy. Thus considerations of the anatomic variations, in the process of diagnosis and treatment of the maxillary and mandibular posterior teeth, should be done by the clinicians.1 A thorough examination of pre-operative and postoperative radiagraphs plays a critical role in endodontic success. Vari...

Root canal anatomy is complex, and the recognition of anatomic variations could be a challenge for clinicians. This case report describes the importance of cone beam computed tomographyic (CBCT) imaging during endodontic treatment. A 23 year old woman was referred by her general dental practitioner with the chief complaint of spontaneous pain in her right posterior maxilla. From the clinical an...

This paper presents theories and algorithms for 3-D root canal model construction from 2-D X-ray images in a clinically practical way: (1) the geometrical rectification algorithm for correcting distorted 2-D X-ray images, (2) the transformation algorithms from 2-D X-ray image coordinate system to unified 3-D reference coordinate system, (3) the merging algorithms and theory for obtaining spatia...

INTRODUCTION This study investigated the accuracy of cone-beam computed tomography (CBCT), peripheral quantitative computed tomography (pQCT), spiral computed tomography (SCT), plain (plain digi), and contrast medium-enhanced digital radiographs (contrast digi) in studying root canal morphology. METHODS The root canal anatomy was analyzed in 95 teeth using CBCT, pQCT, SCT, plain digi, and con...

introduction: the present study was conducted to assess the morphology of mandibular canines using cone-beam computed tomography (cbct) in a north iranian population. methods and materials: for the morphological assessment of mandibular canines, 150 cbct images taken from patients for different reasons were used. the mandibular canines were examined in sagittal, coronal and axial dimensions. th...

OBJECTIVES Cone-Beam Computed Tomography is an alternative imaging technique which has been recently introduced in the field of Oral & Maxillofacial Radiology. It has rapidly gained great popularity among clinicians due to its ability to detect lesions and defects of the orofacial region and provide three-dimensional information about them. In the field of Endodontics, CBCT can be a useful tool...

introduction : to achieve success in treatment, one cannot ignore the knowledge of pulp anatomy. mandibular premolars are considered to be the most difficult teeth for endodontic therapy due to high variability in their canal morphology. it is possible that a relation exists between the crown size and the number of extra canals in these teeth, so this in vitro study aims to investigate the rela...

Identifying and accessing all pulp canals is particularly challenging in the endodontic treatment of teeth with atypical canal configurations. This report describes the nonsurgical endodontic treatment of a maxillary first premolar with three root canals. The prevalence of this unusual morphology is reviewed and suggestions are offered to help dentists identify and treat such teeth. This case r...

OBJECTIVE To determine the internal root morphology and gender variations in mandibular first permanent molars in a Kenyan population. DESIGN In vitro descriptive cross sectional study. SETTING School of Dental Sciences, University of Nairobi RESULTS The mesial root of mandibular first molars had two canals in 96.3% of the teeth in both males and females and-type IV canal configuration wa...
