AIM The purpose of this report is to present a case of endodontic management of a dilacerated maxillary central incisor fused to supernumerary tooth unusually appearing as a labial tubercle using cone beam computed tomography (CBCT) as a diagnostic aid. BACKGROUND Anterior teeth are commonly encountered with aberrant anatomical variations in the crown, number of roots, and root canals. Fusion...

This case report describes an endodontically managed maxillary first molar with an unusual morphology of five canals. Maxillary first molar has one of the most complex root and canal anatomy. The greatest variations observed are the presence of two canals in the mesiobuccal root of maxillary molar, canals in the furcation area and the presence of lateral and accessory canals. The incidence of t...

The aim of this study was to evaluate the effectiveness of gutta-percha and Resilon in filling lateral root canals by using the Obtura II system. Root canals of artificial teeth were prepared using a standard protocol, and lateral canals were made in three thirds of the root canal. The root canals were filled with either Obtura gutta-percha (OB), Endo-points flow gutta-percha (ED), or Resilon (...

BACKGROUND The success of endodontic treatment is greatly affected by the location of the root canals. The purpose of this study was to evaluate the root and canal morphology of permanent maxillary first and second molars in a Polish population using cone-beam computed tomography scanning. METHODS Cone-beam computed tomography (CBCT) scans of maxillary first and second molars the maxilla were...

INTRODUCTION The main goal of endodontic therapy is to prevent or heal apical periodontitis. However, root canal anatomy might present a clinical challenge directly related to the treatment outcome. The purpose of this study was to review published literature related to root anatomy and root canal configuration of the permanent mandibular first molar. METHODS An exhaustive search was undertak...

INRODUCTION High-quality filling of root canals is one of indicators of successful endodontic treatment. However, poor-quality of the filling is still a common phenomenon in the work of general practitioners. Better training of dental students of modern odontology is possible solution of the problem. The aim of this study was to evaluate the quality of root canal filling performed by undergradu...

C-shaped canals are mostly found in mandibular second molars. Studies have shown that frequency ranges from 2.7 to 31%. This study was undertaken to provide further knowledge of the distribution of such canal anatomy, by determining the frequency of C-shaped canals in a sample representing the Lebanese population. Ninety-four mandibular second molars with scheduled endodontic treatment were exa...

INTRODUCTION This study evaluated the working length (WL) modification after instrumentation with WaveOne Primary (Dentsply Maillefer, Ballaigues, Switzerland) reciprocating files and the incidence of overinstrumentation in relation to the initial WL. METHODS Thirty-two root canals of permanent teeth were used. The angles of curvature of the canals were calculated on digital radiographs. The ...

To ensure the long-term success of root canal treatment, it is essential to access, clean, and fill all of the canal spaces. However, the anatomic complexities and variations are constant challenges for successful endodontic therapy.1 The morphology of the maxillary first molar has been extensively studied and reported in the literature. Studies have revealed a high incidence of double canal sy...
