Dental management of the chronic vomiting patient

A review of dental erosion secondary to medical or psychologic causes (or both) has been presented. Clinical signs and symptoms and appropriate restorative therapy have been discussed. Diagnosis and stabilization of the chronic vomiting patient must precede definitive restorative procedures.

Composite laminate veneers with a continuous inorganic phase comprising microporous sintered glass fiber networks

Veneers were made from sheets consisting of a three-dimensional network of sintered ultrafine glass fibers. The sheets were molded by a vacuum-pressure technique and then impregnated with a liquid resin. Impregnation was performed with a method that enabled the depth of penetration to be monitored. The resin was cured with UV radiation under N2 protection. By the use of TiO2-containing resins the veneer achieved an enamel-like appearance. An in vitro toothbrush dentifrice abrasion test showed a high wear resistance and persisting surface luster. Scanning electron and light microscopy showed fairly smooth and flat light-reflecting glass structures in the surface.
