Cytotoxic Study of Three Cements in Gingival Fibroblasts (original) (raw)

Abstract

Objective: It is known that all materials and devices used in the oral cavity can trigger adverse effects. Dental cements, essential for the success of oral rehabilitation, may be responsible for the release of substances that can induce negative effects on cells, including their death. Dental cements are present in the transition between restoration and tooth and, although in small areas, remain in contact with the oral tissues of patients for long periods of time. The aim of this study is to compare the cytotoxic effect of three luting cements, namely resin cement, resin-modified glass ionomer cement and glass ionomer cement, on the cells from gingival fibroblast cell line. Method: We used 3T3 fibroblast cells exposed to different dilutions of medium previously incubated for 24 hours with the 3 different cements. The cements were prepared according to the manufacturer and the resin cement was prepared in 2 different ways: light cured and non-light cured. After an incubation-period...
