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...

Background: Knowledge about the anatomy of root canals is an important facror in the prognosis of  root canal  therapy .The purpose  of  this  study is to derermine  the root  canal anatomy in  mandibalar anterior  reeth and  premolars by clear and dye peneration method. Materials and methods:In this  study, 350 human mandibular anterior teeth and  mandibular  and  maxillary premolars(from e...

background successful endodontic treatment is dependent on the knowledge of root canal anatomy. objectives this study aims to investigate the root canal anatomy of mandibular first molars in an iranian population. materials and methods one hundred human mandibular first molars were collected and stored in 5.25% naocl. radiographic images of the teeth were taken in mesial, distal, and buccal asp...

the aim of this study was to report the endodontic management of right maxillary central incisor having two canals with vertucci canal configuration type iv . internal morphology of root canals is variable and often complex. therefore, to achieve a technically satisfactory endodontic outcome, the clinician must have adequate knowledge of the internal canal morphology and its variations in order...

introduction: the aim of this study was to evaluate the root canal morphology of mandibular first and second molars using cone-beam computed tomography (cbct) in northern iranian population and also to indicate the thinnest area around root canals. methods and materials: we evaluated cbct images of 154 first molars and 147 second molars. by evaluating three axial, sagittal and coronal planes of...

introduction: the purpose of this study was to evaluate the number of distal roots and canals in mandibular first molars and their internal anatomy radiographically within iranian population. materials and methods: a total of 310 distal roots of mandibular first molars were incorporated in this study and evaluated in terms of number of roots and number and types of canals. root canal systems we...

introduction: the aim of this study was to evaluate root canal anatomy of mandibular first molars (mfm) in a selected iranian population using clearing technique. methods and materials: a total of 150 extracted mfms were cleared. the root canal morphology (including the root numbers and root length) and the anatomy of the root canal system (including is the number and type of canals based on ve...

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...

introduction: it is essential for clinicians to have knowledge about root canal configuration, although its morphology varies largely in different ethnicities and even in different individuals within the same ethnic group. the current study reviewed the root canal configuration of root canals in mandibular first and second premolars among iranian population based on independent epidemiological ...
