Study Regarding the Influence of Different Antiseptic Mouthwashes on Surface Roughness of Traditional Glass Ionomer Cements

Abstract

The aim of the study was to evaluate the surface hardness of two different traditional glass ionomer cements after their exposure to two commercial oral rinsing solutions. Fuji IX GP (GC Corporation, Tokyo, Japan) and Ketac Molar Easymix (3MESPE, Germany) were used in the study. Twenty-one cement samples of each material were split in three groups. In control group the samples were stored in artificial saliva (AFNOR NF S90-701) for 14 days. In groups 2 and 3 the samples of each material were immersed in Listerine and in Corsodyl two times on a day for 14 days. Between the immersion periods the samples were stored in artificial saliva. The samples were subjected to microhardness evaluation using digital microhardness tester (Micro-Vickers Hardness System CV-400DMTM, CV Instruments Namicon). Significant results were obtained when compared the surface hardness of both glass ionomer cements after their immersion in Listerine and in Corsodyl to control group. The surface hardness of Fuji IX in control and in study groups was significantly higher when compared to Ketac Molar Easymix In the conditions of the study, Listerine and Corsodyl decreased the surface hardness of Fuji IX GP and Ketac Molar Easymix glass ionomer cements.
