AIM To highlight anatomical variation in the mandibular canine. SUMMARY Two clinical case reports are 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 can...

The aim of this study was to investigate, in vitro, the percentage of filling of simulated lateral canals in teeth obturated with TP medium and standardized gutta-percha points. Twenty human mandibular canines were prepared with LA Axxess (SybronEndo) and K³ Endo rotary system (SybronEndo) up to a #50 file, according to the Free Tip Preparation Technique. During instrumentation, the root canals...

PURPOSE The purpose of this in vitro study was to determine whether placement of a resorbable collagen barrier at the apical one third of the root canal could prevent extrusion of pulpectomy filling material. METHODS Twenty-five extracted primary mandibular second molars, with at least two thirds of root length remaining, were used. The apical third of each root was covered with utility wax, ...

We report a clinical case of horizontal root fracture in the mandibular first premolar induced by a traffic accident. The fractured tooth spontaneously healed and diagnosed radiographically after 2 years. Fractured fragments were separated by a narrow radiolucent line and the edges were rounded, and healing of the tooth is likely to be related to interproximal connective tissue healing. Our cas...

Background and Aim: The aim of this study was to investigate the relation between bucco-lingual dimension and root canal morphology in mandibular incisors. Materials and Methods: A total of 100 mandibular incisors were used in this study. The bucco-lingual dimensions of each tooth were measured at the level of cemento-enamel junction by using a digital caliper. Thereafter, the crowns were groun...

BACKGROUND To evaluate the incidence of flare-ups and identify the risk factors including age, gender, tooth type, number of root canals, initial diagnosis, the type of irrigation regimen, treatment modality and the number of visits, in patients who received root canal treatment from January 2002 to January 2008. METHODS Records of 1819 teeth belonging to 1410 patients treated by 1 endodontic...

CASE REPORT This case report describes the outcome of a number of retreatments on a failed root filling in a maxillary first molar. The patient wanted all amalgams replaced by tooth-coloured Cerec restorations, including one in a symptomless maxillary molar. This tooth had a pulpotomy or a poorly done root-canal treatment 10 years earlier. The molar was root-canal retreated before placing the C...

The past 10 years have witnessed more significant changes in the art and science of endodontics than the previous 100 years. This observation is no surprise, given that change is our only constant. The rate of change, however, has been anything but constant. The rate has accelerated so fast that all clinicians in the field of dentistry need a reliable source to guide us in what works. What work...

The aim of this case report was to present the non-surgical root canal treatment of the geminated maxillary anterior lateral incisor tooth. A 50-year-old female patient was referred for endodontic treatment of her maxillary right lateral incisor. In the clinical examination, a large crown was observed in the right maxillary incisor region when compared with the left maxillary lateral incisor. T...

OBJECTIVES The aim of the present study was to determine radiographically the different reasons and problems of endodontic treatment failure. METHODS The periapical radiographs of 100 patients with one hundred teeth (130 root canals) were examined to identify the problems and failures of endodontic treatment. The various reasons of failure that is under filling, poor filling, over filling and...
