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...

Coronal fractures of permanent dentition are the most frequent type of dental injury. If the original tooth fragment is retained following fracture, the natural tooth structures can be reattached using adhesive protocols. The development and use of fiber-reinforced composite root canal posts make possible the reattachment of the crown esthetically. This case report presents a clinical technique...

Animal bites are extremely common in the United States and their incidence is increasing [1-5]. Dog bites are most common, usually producing variable flesh wounds without bony injury. Reports of fractures from bites are difficult to find. However, canine bites present a special hazard to the infant skull which is relatively thin and incompletely mineral ized . One compound depressed skull fract...

From a dental viewpoint, incisor-luxation fractures in horses are fraught with complexities. Luxation fractures are defined as the dislocation of a tooth out of its alveolus without being totally avulsed from the mouth. These are dental emergencies with far-reaching implications. The periodontal and endodontic survival of the involved teeth depends on how these cases are handled. Owners should ...

Age determination is an important tool in wildlife studies. Estimating the age of animals in the field using tooth wear criteria may be subject to error as a result of variations between individuals, habitats and populations. Data on age estimation of leopards and tooth wear characteristics are lacking. Nineteen leopards in Namibia were assessed for tooth eruption and wear. Between 1991 and 199...

Dens evaginatus is a disturbance in tooth formation that appears clinically as an accessory occlusal tuberculated cusp composed of enamel and dentin, usually enclosing pulp tissue. The tubercle often fractures or is worn away, with subsequent pulp exposure leading to pulpal inflammation, necrosis, and periapical inflammation. When this happens to an immature tooth, diagnosis may be complicated ...

A clinical study was done on 36 original cases of vertical root fractures along with the data gathered from 32 cases published previously in the literature. Vertical root fractures most frequently occur in posterior teeth in patients between 45 and 60 yr of age. The average elapsed time between the endodontic treatment and the subsequent diagnosis of vertical fracture was found to be approximat...

Introduction: Vertical root fractures (VRFs) in endodontic treatment teeth are most serious complication. VRFs have a poor prognosis and usually result in tooth extraction. The purpose of this study was to evaluate the clinical outcomes of mineral trioxide aggregate (MTA) filled teeth for VRFs using by dental operate microscope (DOM). Methods: Fifty-two endodontic treatment teeth with VRFs were...

Young patients are often frequently involved in traumatic dental injuries. The most common type fracture in permanent anterior teeth is a crown fracture. Direct restorative procedures using composite and fiber posts can be an esthetic and conservative approach in the case of extended fracture of an anterior root-filled tooth with little remaining coronal tooth structure. Currently, prefabricate...

In pediatric patients, anterior teeth with fractures that extend subgingivally require a complex treatment plan that addresses biologic, esthetic, and functional factors, such as mastication and speech. The purpose of this clinical report was to describe a technique using indirect composite restoration to restore a subgingivally fractured permanent maxillary right central incisor in a 10-year-...
