In vitro cytotoxicity of solid epoxy-based dental resins and their components

摘要

Objective: the objective of this study was to evaluate the efffect of adding a spiroorthocarbonate (SOC) or a polyol on the cytotoxicity of epoxy-based dental resins. Methods: Resins contained one of the epoxies: diglycidyl ether Bisphenol A (yGY-6004); 3, 4-epoxycyclohexanem,ethyl-3, 4-epoxycyclo- Hexane carboxylate (UVR-6105); vinyl cyclohexane dioxide (ERL-4206) or the three-epoxy mixture (Epoxy-M). the SoC was t/t -2, 3, 8, 9- Di (tetramethylene)-1, 5, 7, 11-tetraoxaspiro [5.5] undecane (SOC). The polyols were polytetrahydrofuran (p-THF-250) and poycaprolactone Triol (TONE-301).
