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...
متن کاملEstrogenicity of resin-based composites and sealants in dentistry.
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 کاملMarginal seal evaluation of different resin sealants used in pits and fissures. An in vitro study.
UNLABELLED ATM: Oral health is important for everyone, but specially for children and people requiring special care owing to impaired manual ability. Primary prevention, with correct oral hygiene, proper diet, use of fluoride and pit and fissure sealants, can reduce caries risk thereby improving patients' quality of life. The first aim of this paper was to assess the marginal microleakage of di...
متن کاملStability of two resin combinations used as sealants against toothbrush abrasion and acid challenge in vitro.
OBJECTIVE To test the stability of two conventional adhesives when combined with a low-viscosity caries infiltrant used for sealing sound enamel against toothbrush abrasion and acid challenge in vitro. MATERIALS AND METHODS Bovine enamel discs (Ø = 3 mm) randomly assigned to three groups (n = 10/group) were etched with 37% phosphoric acid for 30 s and treated with resins of different monomer ...
