Perbandingan Kekerasan Permukaan Resin Komposit Nanofiller Setelah Perendaman Dalam Obat Kumur Beralkohol Dan Non Alkohol

Abstract

Tooth decay is a major problem for dental and oral health in the surrounding environment. Process Degenerative diseases that start in the enamel and spread to the dentin are part of a disease known as dental caries. Composite resin is a material used for restorations. One of the mechanical properties of nanofiller composite resin, namely surface hardness, can affect the durability of composite resin. The cause that can affect the surface hardness of the composite is the use of mouthwash. Mouthwash, both alcoholic and non-alcoholic, can help maintain healthy teeth and mouth. The aim of this research was to determine the comparison of the surface hardness of nanofiller composite resin after immersion in alcoholic and non-alcoholic mouthwash. Materials and methods used are Experimental Laboratories with the Post-test With Control Group Design research design used. A total of 30 nanofiller composite resin samples were soaked for 24 hours in three different groups, namely group I which received distilled water as a control, group II which received mouthwash with 21.6% alcohol, and group III which received mouthwash without 0% alcohol. The Vickers hardness test is the test method used. The results of this research are that the Kruskal-Wallis test and the Mann Whitney U follow-up test show that the surface hardness comparison is not significant for the nanofiller composite resin in the distilled water and alcohol mouthwash groups, namely (p-value> 0.05), and the surface hardness comparison is significant. on nanofiller composite resin occurred in the alcoholic and non-alcoholic mouthwash immersion group (p-value <0.05). Conclusion: There is a comparison of the immersion surface hardness of alcoholic and non-alcoholic mouthwash in nanofiller composite resin. Soaking alcoholic mouthwash causes the surface hardness value to be very low.
