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 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 most difficult maxillary teeth for endodontic treatment are the maxillary first molars (mfm) due to their complex root canal anatomy. the presence of two roots and c-shaped canals in mfms has been reported in rare cases. the present case reports root canal treatment of mfm with two roots, where the palatal and buccal roots were joined together in a c-shaped configuration .

thorough understanding of the anatomic and internal morphology of a root canal system is absolutely essential for the success of endodontic treatment. since permanent maxillary first molars have shown variation in internal anatomy, morphology, this tooth has been reviewed extensively. presence of two canals in a two-rooted maxillary first molar has rarely been reported in studies describing too...

Objectives: The aim of this literature review was to analyze the root canal shape of human teeth described in anatomical studies as recent wide use of fiber posts resulted in a new interest for the anatomy of coronal and middle portions of the canal, where post-space should be prepared, in order to achieve the best fiber post fitting to the post-space. Material and methods Original scientific p...

Endodontic therapy of mandibular molars is a challenging task due to its varied root canal morphology. A mandibular first molar with additional buccal root (Radix paramolaris) and additional distolingual root (Radix Entomolaris) is an example of its varied anatomy. A successful management of atypical root canal configurations is an important aspect in determining the success rate of root canal ...

accurate diagnosis of the root canal morphology and anatomy is essential for thorough shaping and cleaning of the entire root canal system and consequent successful treatment. this report describes a case of maxillary second premolar with two roots and three root canals (two mesial and distal palatal canals). the case report underlines the importance of complete knowledge about root canal morph...

The spontaneous translocation of the short arm of chromosome 1 of rye (1RS) in bread wheat is associated with higher root biomass and grain yield. Recent studies have confirmed the presence of QTL for different root morphological traits on the 1RS arm in bread wheat. This study was conducted to address two questions in wheat root genetics. First, does the presence of the 1RS arm in bread wheat ...
