The trefoil configuration of the lumbar vertebral canal. A study of South African skeletal material.
The shallow lateral recesses of the trefoil shape of the lumbar spinal canal have been implicated in the production of the spinal stenosis syndrome. In the present study, 485 skeletons of South African Blacks and Whites were examined in order to establish the incidence and possible genesis of the trefoil configuration. The overall incidence was 14 per cent, with little variation between the sex...
The mesiobuccal root of the maxillary molars is well known to pose a hindrance during endodontic therapy. Presented here is a case of a maxillary left second molar where three canals were located in its mesiobuccal root with the use of visual and diagnostic aids. Difficulties encountered during the process of unveiling the tooth's internal anatomy were discussed. The dilemmas encountered pertai...
OBJECTIVE To evaluate differences in the root and canal configurations of mandibular permanent anterior incisors and canines in an Iranian population by means of Cone Beam CT (CBCT) images. MATERIALS AND METHODS Four hundred CBCT images of mandibular permanent incisors and canines that met the inclusion criteria were evaluated. Vertucci's classification was used to evaluate the number of root...
objectives: it is essential for clinicians to have adequate knowledge about root canal configurations; although its morphology varies largely in different ethnicities and even in different individuals with the same ethnic background. the current study aims to review the root canal configurations of mesiobuccal roots of maxillary first molars in an iranian population based on different epidemiol...
OBJECTIVES The success of endodontic treatment is based on cleaning and shaping of the root canals. The root canals have complex morphology and wide individual variations. The objective of this study was to analyze root canals morphology and existence of extra canals in maxillary molars in Saudi subpopulation. METHODS Freshly extracted maxillary first molars (n=100) were included in this stud...
Introduction To evaluate the prevalence of C-shaped root canals in mandibular molars using cone beam computed tomography (CBCT) in a subpopulation of Central India. Materials and Methods CBCT scans of patients from diagnostic imaging center were selected in accordance with the criteria given by Fan et al. (2004) for C-shaped canals. A total of 238 CBCT scans fulfilled the inclusion criteria a...
the maxillary first premolar may present large number of anatomic variations. the clinician should be aware of the configuration of the pulp system. maxillary first premolars usually have two canals. the incidence of three canals in these teeth is quite rare. this case report presents the diagnosis and clinical management of a maxillary first premolar with two distinct canals in the apical thir...
Aim: The aim of this study was to survey the root canal morphology of mandibular incisor teeth in a Palestinian population using radiographic approach. Materials and Methods: Five hundred and twenty two extracted mandibular incisor teeth were randomly collected from Palestinian population. The teeth were radiographed from a mesiodistal direction and examined for the presence of a second canal a...
STATEMENT OF PROBLEM The knowledge of the pulp anatomy plays an important role in the success of endodontic treatments. PURPOSE The aim of this study was to determine the root and canal morphology of the mandibular second molar teeth in an Iranian population. MATERIAL AND METHODS One hundred intact human mandibular second molars were collected. The teeth were examined visually and the numbe...
