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...

anatomy of the root canal system always effects endodontic treatment outcome. mandibular premolar teeth show extreme variations in root canal morphology. first premolars usually exhibit basic one root and one canal anatomy. the occurrence of three roots in mandibular first premolar has not been commonly reported in literature. this article reports a case of successful nonsurgical endodontic man...

thorough knowledge of the morphology and internal anatomy of the root canal system is essential, because it determines the successful outcome of endodontic treatment. the main goal of endodontic treatment is to prevent apical periodontitis and/or to promote the healing of periapical lesion. presence of two canals or roots on the palatal side of the first maxillary molar has rarely been reported...

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...

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 ...

successful endodontic therapy depends on adequate mechanical and chemical debridement of the canal which requires knowledge of the canal morphology. conventional radiography has been used to evaluate the canal type; however, direct digital radiography has recently been practiced for this purpose due to the shortcomings of conventional radiography. the aim of the present study was to compare the...

Introdouction: Variations in root canal morphology pose a challenge for successful endodontic treatment. The root canal anatomy of the maxillary first molar has been often described as three roots with four canals (two mesiobuccal, one distobuccal, and one palatal). The occurrence of two palatal canals in one palatal root is quite rare. This report represents the case of a maxillary first molar...

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 complexity of the root canal system presents a challenge for the practitioner. this systematic review evaluated the papers published in the field of root canal anatomy and configuration of the root canal system in permanent maxillary second molars. methods and materials: all articles related to the root morphology and root canal anatomy of the permanent maxillary second molars...
