A technique utilizing modified Gates Glidden burs and ultrasonics has recently been advocated to remove fractured instruments from root canals. Varying extents of tooth structure are removed during this procedure, potentially leading to complications. This study evaluated the in vitro and in vivo complications associated with fractured file removal. Fractured instrument fragments were removed f...

This communication presents the treatment of 15 cases of c-shaped canals in molars and their treatment outcome with two different obturation methods. The data from 901 patients who received root canal treatment in a molar tooth were examined regarding c-shaped root canals, their treatment and their status one year post op. Among the 901 cases, 15 molars had a c-shaped root canal morphology (1,6...

There is lot of anatomical variation in the mandibular canine. A clinical case report is presented to illustrate anatomical variation in the human mandibular canine. Endodontic treatment may sometimes fail because morphological features of the tooth adversely affect the treatment procedures. Many investigators have reported the anatomical variations associated with mandibular canines. Mandibula...

The objective of this study was to compare the adaptation of mechanically softened gutta-percha to the root canal wall in the presence and absence of smear layer. The root canals of 20 freshly extracted human maxillary incisors were cleaned and shaped. Prior to obturation, 10 root canals were irrigated with 20 ml of 50% citric acid followed by 20 ml of 5.25% sodium hypochlorite. All canals were...

INTRODUCTION Vertical root fracture inevitably leads to tooth extraction. Thus, root filling with obturating materials and sealers that can reinforce the tooth would be an ideal way to reduce fracture in root treated teeth. This study aimed to assess the fracture resistance of roots following the application of different sealers including Epiphany, iRoot sealer and AH-plus. METHODS AND MATERI...

The smear layer in endodontically instrumented root canals first reported in 19751 is both organic and inorganic in composition. 2 The inorganic material in the smear layer is composed of tooth structure and some nonspecific inorganic contaminants. 2 The organic components may consist of heated coagulated proteins, necrotic or viable pulp tissue, and odontoblastic processes plus saliva, blood c...

Root amputation and retrograde filling of pulp canals is a useful technique in the treatment of periapical dental infections in horses, thus allowing tooth preservation. The limitations of the technique are the need for careful case selection and the difficulty in creating a hermetic apical seal. Authors’ addresses: Royal Veterinary College, Hawkshead Lane, North Mymms, Hatfield, Hertfordshire,...

Introduction: Pulpectomy helps in preserving a pulpally involved primary tooth by extirpating the diseased pulp associated with microorganism and debris from canal obturating an antibacterial resorbable filling material Aim: To evaluate compare obturation quality interms of underfilling,optimal filling, over fillings, voids single rooted teeth amongst 4 different techniques using cone beam comp...

This is a rare case report of apexification in an immature permanent mandibular first molar. Calcium hydroxide was used for apical root closure of both the mesial and distal canals. Root closure occurred after 13 months following which obturation of the tooth was completed.

p r r o w t bstract berrations in the root canal anatomy are a commonly ccurring phenomenon. A thorough knowledge of the asic root canal anatomy and its variations is necessary or successful completion of the endodontic treatment. andibular second premolars usually have a single root nd a single root canal. The incidence of three separate oots itself in this tooth is quite rare, and the presenc...
