| Summary: | In resin modified glass ionomer cement (RMGIC) restoration, one of surface coating agent which commonly used is varnish. The negative effects of varnish are easily dissolved in mastication and evaporated so that porosity occur. To solve the negative effects of varnish, hence nanofilled self-adhesive light cured protective coating is used. The aim of the study was to compared effectivity of varnish and nanofilled self-adhesive light cured protective coating to protect discoloration of RMGIC.
Twenty disc specimens with 15 mm diameter and 1 mm thick were divided in two groups. First group was applicated with nanofilled self-adhesive light cured protective coating and second group was applicated with varnish. Both groups were immersed in steeping black tea which changed every 24 hours for 7 days. The measurement of discoloration was done before all specimens immersed in steeping black tea and after 7th days. The data of measurement were analyzed by independent t-test.
This study between RMGIC was applicated with nanofilled self-adhesive light cured protective coating and RMGIC was applicated with varnish showed there were significant statistically differences of discoloration (p<0,05). This conclusion of this study was nanofilled self-adhesive light cured protective coating was more effective to protect discoloration compared with varnish. |
