UNLABELLED The diagnoses of cracked teeth and incomplete coronal fracture have historically been symptom based. The dental operating microscope at 16x magnification can fundamentally change a clinician's ability to diagnose such conditions. Clinicians have been observing cracks under extreme magnification for nearly a decade. Patterns have become clear that can lead to appropriate treatment pri...

This case report describes a unique C-shaped mandibular second premolar with four canals and three apical foramina and its endodontic management with the aid of cone-beam computer tomography (CBCT). C-shaped root canal morphology with four canals was identified under a dental operating microscope. A CBCT scan was taken to evaluate the aberrant root canal anatomy and devise a better instrumentat...

INTRODUCTION Coronal anatomic variations in permanent maxillary molars are unusual; conversely variations involving the number of root canals or number of roots are more common. METHODS AND MATERIALS This case report presents a successful nonsurgical endodontic therapy of left maxillary first molar with three roots and seven root canals. This unusual morphology was diagnosed using a dental op...

The aim to publish this case report is to emphasize the clinical challenges involved in endodontic treatment of rare dental anomaly like Taurodontism. Endodontic management of a taurodont tooth has been described as complex and challenging. Present case is an attempt to emphasize the challenges an Endodontist encounters while treating Taurodontism affecting the molars of permanent dentition. An...

We aim to present a case of obliterated root canal which was successfully treated in our dental faculty using these new techniques. Teeth with calcified root canals referred for endodontic treatment pose pa rticular diagnostic and treatment challenges. Usually these are intact traumatized anterior teeth without symptoms except of slight discoloration, without apical radiolucency. The thorough k...

The separate distolingual (DL) roots of three-rooted mandibular first molars are thought to be too difficult for performing apical surgery. This article represents microsurgical treatment of a three-rooted mandibular first molar with a separate DL root. The procedure includes incision and flap retraction, osteotomy, apicoectomy, retropreparation and retrofilling of the root canal, using micro i...

An examination of 1732 conventionally treated maxillary molars was made in an attempt to determine the percentage of MB2 canals that could be located routinely. The teeth examined were 1096 first molars, 611 second molars, and 25 third molars. The results were recorded on a modified computer program over an 8-yr period of time. An interesting trend was noted. The MB2 canal was found in 802 (73....
