Intentional replantation has been long considered to be the onlyrecourse for saving a tooth when other options like traditional root canal therapy and surgery are inconceivable. The article discusses intentional replantation as a treatment option for afallible case of broken instrument in the distal canal of left mandibular second molar. The critical factor required for the success of intention...

Dental health was evaluated in two populations of raccoons (Procyon lotor) in western Illinois (USA); one was from a rural agricultural area with low human density and the other from a nearby state park heavily used by humans and raccoons. From 1989 through 1993, 300 raccoons were live-trapped in the agricultural area and 246 raccoons were live-trapped in the park. Oral health was assessed usin...

This paper examines portfolios within the framework of a dynamic asset-pricing model when investors can trade equity assets as well as bonds of many different maturities. We specify the model so that investors have demand for both a risky and a safe income stream. We characterize the resulting optimal equilibrium stock and bond portfolios and document that optimal bond investment strategies par...

Tooth Anatomy: Teeth are roughly broken up into three layers: enamel, dentin, and pulp. The innermost layer is the endodontic system (root canal or pulp). It contains the nerves, blood vessels, and connective tissue which supply and nourish the tooth during life. The blood and nervous supply enters the tooth through the very bottom or apex of the root. The outer layer of the tooth crown is enam...

Irregular (so-called broken) plural identification in modern standard Arabic is a problematic issue for information retrieval (IR) and language engineering applications, but their effect on the performance of IR has never been examined. Broken plurals (BPs) are formed by altering the singular (as in English: tooth teeth) through an application of interdigitating patterns on stems, and singular ...

The best plan for success is to begin with the end in mind. It generally is agreed that the successful treatment of a badly broken down tooth with pulpal disease depends not only good endodontic therapy, but also on good prosthetic reconstruction of the tooth after endodontic therapy. The primary purpose of the post is to retain a core that can be used to retain definitive prostheses. A post an...

The goal of dentistry is to preserve functional dentition to promote the general health, longevity, and productivity of the horse; however, throughout recorded equine dental history, exodontia has been the primary treatment for diseased teeth. This treatment predisposes the equine dentition to subsequent periodontal disease, malocclusion, and additional tooth loss. Restorative dentistry is the ...

Tooth development is regulated by epithelial-mesenchymal interactions and their reciprocal molecular signaling. Bone morphogenetic protein 2 (Bmp2) is essential for tooth formation. However, the role of Bmp2 during enamel formation remains unknown in vivo. In this study, the role of Bmp2 in the regulation of postnatal enamel formation was investigated via the conditional ablation of Bmp2 in ena...

Increasing interest has developed among dentists regarding alternatives to traditional full-coverage crowns for the restoration of extensively broken-down teeth that are both aesthetic and less destructive of remaining tooth structure. Indirectly fabricated resin composite onlays may offer a viable and cost-effective treatment option in such cases. This paper describes the clinical rationale fo...

A case of infective endocarditis caused by Rothia dentocariosa is described in a 53 year old man with a history of rheumatic fever. R dentocariosa is a component of the oral microbiota and has only rarely and recently been recognised as a human pathogen. In this patient the oral flora was the probable source of infection, with a broken molar tooth providing the probable avenue for infection.
