Estrogenicity of resin-based composites and sealants used in dentistry.
We tested some resin-based composites used in dentistry for their estrogenic activity. A sealant based on bisphenol-A diglycidylether methacrylate (bis-GMA) increased cell yields, progesterone receptor expression, and pS2 secretion in human estrogen-target, serum-sensitive MCF7 breast cancer cells. Estrogenicity was due to bisphenol-A and bisphenol-A dimethacrylate, monomers found in the base p...

Estrogenicity of Resin-based Composites and Sealants in Dentistry The recent article "Estrogenicity of Resinbased Composites and Sealants Used in Dentistry," appearing in the March 1996 Environmental Health Perspectives (EHP 104:298-305) raises some familiar concerns that critics of the profession have espoused. Historically, many of the materials that have been common in the dental armamentari...
متن کاملProperties evaluation of silorane, low-shrinkage, non-flowable and flowable resin-based composites in dentistry
Purpose. This study tested the null hypothesis that different classes of direct restorative dental materials: silorane-based resin, low-shrinkage and conventional (non-flowable and flowable) resin-based composite (RBC) do not differ from each other with regard to polymerization shrinkage, depth of cure or microhardness. Methods. 140 RBC samples were fabricated and tested by one calibrated opera...
متن کاملthe effect of drinks and temperature on the staining of resin composites coated with surface sealants
statement of problem: surface staining of resin composite by dietary factors may be modified by the placement of a low-viscosity surface sealant aimed at reducing surface voids and defects occurring after light-curing and polishing. objectives: the aim of this study was to investigate the staining effect of various drinks and temperatures on the surface sealant (fortify plus™) sealed on a nano-...
متن کاملEffects of Carbamide Peroxide Bleaching Gel on Color of Silorane- and Methacrylate-based Resin Composites
Introdouction: Bleaching has become a common treatment for improving the appearance of natural teeth. However, the need to protect dental restorations from bleaching agent exposure is inevitable, as these agents may change the color of restorative materials by oxidation. Filtek P90 composite resin has recently been introduced with the aim of decreasing polymerization shrinkage. The purpose of...
