The purpose of the study was to compare the treatment outcome of extractions and nonextractions of teeth in the lines of mandibular fractures and to determine the most common complications. A Quasi-experimental study was undertaken in the Department of Oral and Maxillofacial surgery, Khyber college of Dentistry Peshawar from January 2007 to January 2008. A total of 100 patients having tooth in ...

statement of problem: it is yet unclear whether fiber-reinforced composite posts can enhance the mechanical properties and prevent vertical fractures of teeth under chewing loads. purpose: the purpose of this study was to compare the fracture resistance and failure mode of endodontically treated teeth restored with three different post systems. materials and methods: thirty-six maxillary canine...

bacterial leakage and root fractures are the most important reasons of root canal treatment failure. due to the lack of adhesion of gutta percha to the canal walls, resilon has been introduced as a root-filling material able to bond to the root walls. metal posts may predispose the tooth walls to oblique and vertical fracture which usually leads to tooth loss; whereas, fiber posts may reinforce...

Introduction. Root fractures, defined as fractures involving dentine, cementum, and pulpal and supportive tissues, constitute only 0.5-7% of all dental injuries. Horizontal root fractures are commonly observed in the maxillary anterior region and 75% of these fractures occur in the maxillary central incisors. Methods. A 14-year-old female patient was referred to our clinic three days after a tr...

Crown-root fractures in primary teeth are rare, with a wide variation of patterns that make diagnosis and treatment difficult. The aim of this study was to present a case series of crown-root fractures in primary teeth of children who attended a reference center. The study followed 28 cases of crown-root fractures in 26 children, representing 4% of the total number of attendees over 11 years of...

BACKGROUND Mandibular fracture is an important surgical condition in our environment and elsewhere in the world. OBJECTIVE The purpose of this study is to clinically determine the most common sites of the mandible prone to fracture. PATIENTS AND METHOD This two-year prospective study was carried out at the Dental and Maxillofacial clinic, University of Calabar Teaching Hospital, Nigeria, in...

OBJECTIVE To estimate the relative risk of mandibular angle fractures among people with a lower third molar compared with those without a lower third molar. METHODS Data for a case-control meta-analysis were obtained by performing a literature search in MEDLINE and EMBASE to identify suitable observational studies. To be included, studies had to present data on patients with mandibular fractu...

Immediate implant placement is most commonly indicated when tooth extraction performed owing to pathologies such as unrestorable caries or fractures. The primary advantage of this treatment modality the diminution healing time and reduced alveolar process resorption. Regenerative materials can be used an adjunct with implants in order triumph high survival rate enrich good esthetic outcome. Thi...

This article presents a study of fatigue-crack propagation behavior in Nitinol, a 50Ni-50Ti (at. pct) superelastic/shape-memory alloy, with particular emphasis on the effect of the stress-induced martensitic transformation on crack-growth resistance. Specifically, fatigue-crack growth was characterized in stable austenite (at 120 8C), superelastic austenite (at 37 8C), and martensite (at 265 8C...

Abstract Aim: To evaluate the risk of complications associated with retaining or extracting an asymptomatic third molar in line angle fracture. Aiming to seek a consensus whether molars should be extracted retained during surgical repair mandibular fractures. Method A retrospective study was undertaken at Queen Elizabeth Hospital, Birmingham. 150 patients across span three years underwent open ...
