Abstract
|
|
|
This studies were planned to evaluate the evaluate the cytotoxicity of cured experimental composite resin using a cell culture method, and the hardness changes ofit stored in various aqueous acids and ethanol with considerations that solubility
of
resin
surfaces will occure the decrease of hardness should be related with toxicity occured by elucited components. Cytotoxicity of experimental resins were tested by agar overlay. methods, and some solutions in which disc type resin specimens will be
stored
were prepared by dilution of ethanol or acids into distilled water. The microhardness of experimental and commercial dental restorative composite materials exposed to various chemicals were measured with micro Vicker's hardness tester.
@ES Following conclusions were drawn:
@EN 1. KCR-22, experimental composite resins prepared in this study exhibited the same degree of cytotoxicity with commercial products.
