Perbedaan Kekerasan Mikro Giomer dan Kompomer setelah Prosedur In Office Bleaching menggunakan Bahan Karbamid Peroksida 45%

Abstract

Teeth whitening techniques using carbamide peroxide has been approved in several major countries like USA, Canada, and Europe because it is safer, cheaper, and also effective for vital tooth whitening procedure than hydrogen peroxide. Giomer and
Compomer are restorative material that combines the advantageous properties of composite resin with glass ionomer cement. The purpose of this study was to determine differences of giomer and compomer microhardness after the proceure in office bleaching using carbamid peroxide 45%.

The study was conducted on 20 specimens giomer and 20 specimens compomer that have been applied using carbamid peroxide 45%. The specimens were stored in artificial saliva at a temperature 37°C for 7 days before microhardness was tested
using the Vickers Hardness Tester (Buehler, Germany). Microhardness value were analyze by independence sample t test at confidence level 95% (a = 0,05).

Independence sample t test results showed that there were significant differences in microhardness giomer and compomer after using bleaching agent carbamide peroxide 45% (p<0,05). The conclusion of this study is that there are differences in surface micro hardness giomer and compomer after treatment with carbamide peroxide 45%. Giomer microhardness is higher than compomer after treatment with bleaching agents carbamide peroxide 45%.
