The immediate placement of implants in the fresh extraction sockets of infected teeth with periradicular and periapical lesions is contraindicated because of both the infection and the loss of architecture required for proper implant placement. There are 4 approaches for implant replacement of a hopeless tooth with lesions: (1) extraction and delayed implant placement; (2) extraction, debrideme...

Extraction of the lower third molar is one of the most common procedures performed in oral surgery. In general, impacted tooth extraction involves sectioning the tooth’s crown and roots. In order to divide the impacted tooth so that it can be extracted, high-speed air turbine drills are frequently used. However, complications related to air turbine drills may occur. In this report, we propose a...

Should a tooth with pulpal involvement be saved through endodontic therapy, or extracted and replaced with a single tooth implant? Within the limitations of the existing literature, this systematic review of treatment outcomes found that initial endodontic treatment had a high long-term survival rate, equivalent to replacement of a missing tooth with an implant-supported restoration. Single too...

PURPOSE The purpose of this study was to examine the patient- and treatment-related etiologic factors of external root resorption. MATERIALS AND METHODS This study consisted of 163 patients who had completed orthodontic treatments and taken the pre- and post-treatment panoramic and lateral cephalometric radiographs. The length of tooth was measured from the tooth apex to the incisal edge or c...

BACKGROUND Tooth mortality is important in evaluating dental care as tooth loss is a reflection of cumulative effects of past disease and treatment practices. AIM The aim of this study is to analyze the pattern of tooth mortality among pediatric dental patients treated at the University of Benin Teaching Hospital, Benin City, Nigeria. SUBJECTS AND METHODS This was a retrospective study of p...

On a sample of 174 X-rayed dogs a statistical analysis was compiled of oligodontia, post-extraction state, impaction and tooth fracture. A total of 261 anomalies were found. The most frequently observed condition was oligodontia (62%) followed by tooth fracture (23.7%), impaction (7.6%) and post-extraction state (6.5%). The majority of patients (28) comprised German Hunting Terriers where, from...

F ollowing extraction of a natal or neonatal tooth, continued growth of the dental papilla may occur and a tooth-like form may develop.'^ This report describes an atypical tooth form (probably the result of continued growth of the retained dental papilla) that abscessed and may have caused delayed eruption of the adjacent primary lateral incisor. A 13-month-old white male presented to the autho...

background and aims: one of the main goals of standard orthodontic treatment is having the roots of teeth adjacent to extraction sites parallel to each other. the purpose of this study was to compare standard edgewise and preadjusted straight wire (mbt) methods in achieving this goal. materials and methods: for comparing root parallelism, 228 maxillary quadrants and 225 mandibular quadrants of ...
