Maxillary premolars exhibit variable root canal morphology, but it is quite rare to find three canals in their root system. The aim of this case report is to present the diagnosis and clinical management of a patient with anatomical variation of having three root canals in the maxillary first premolar. Three-canalled maxillary premolars are quite an endodontic challenge. A discussion is provide...

Background: Prediction the width of unerupted permanent canines and premolars is far important in assessing the space available to them in an attempt to prevent the future malocclusion. The present study utilized the combined mesio-distal crowns widths of maxillary and mandibular central incisors and first molars to predict the combined mesio-distal crowns widths of maxillary and mandibular can...

statement of the problem using cbct to determine root morphology minimizes rate of treatment failure and adverse effects, such as gouging and perforations. purpose the aim of this study was to assess morphology of root canals using cbct scans. materials and methods in this cross-sectional study, conducted in the radiology department of hamadan dental school in 2011‒2012, 66 cbct scans were stud...

Hopeless retained deciduous teeth without permanent successors pose a restorative challenge for clinicians as well as certain clinical problems for patients. Compromised aesthetics, shifting of adjacent teeth, altered occlusion, and supereruption of teeth are examples of problems that can arise when a permanent tooth is congenitally missing. Mattheeuws, et al1 reported that the mandibular secon...

In this study, endodontic treatments of maxillary second premolars with unusual anatomical configuration were presented. Maxillary second premolars usually have one root with one or two root canals. The occurrence of variations in anatomical configuration is also common; therefore, it must be taken into account in clinical and radiographic evaluation during the endodontic treatment. These teeth...

Familiarity with the normal and abnormal anatomy of the root canal system is essential for successful root canal treatment. The possibility of concomitant three-rooted and three- canalled maxillary and mandibular premolars are extremely rare. The purpose of this paper was to report a case with a three-rooted maxillary first premolar and two three-rooted mandibular premolars.

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 The purpose of this study was to evaluate the cephalometric alterations in patients with Angle Class II division 1 malocclusion, orthodontically treated with extraction of two maxillary premolars. METHODS The sample comprised 68 initial and final lateral cephalograms of 34 patients of both sex (mean initial age of 14.03 years and mean final age of 17.25 years), treated with full fix...

OBJECTIVES A study was undertaken to assess the prevalence of taurodontism in premolars in a group of adult dental patients in Trinidad and Tobago since there is no such data available for the region. METHODS Periapical and orthopantomograms of 1090 randomly selected patients were examined for the presence of an apically displaced pulp chamber without the usual constriction at the cementoenam...
