Daftar Isi:
- In-office bleaching using hydrogen peroxide 38% is a command procedure nowadays. Class V restorations using resin composite and resin modified glass ionomer cements (RMGIC) often found in bleaching patients. The aim of this study is to see microleakage of class V restorations using resin composites and resin modified glass ionomer cements (RMGIC) after bleaching. This study use 32 maxillary premolar that prepared round, 5 mm diameter and 2 mm depth, on the buccal surface placed 1 mm from cementoenamel junction coronally. Subject divided into four groups. Group I is resin composite group without bleaching, group II is resin modified glass ionomer cement without bleaching, group III is resin composite with bleaching and group IV is resin modified glass ionomer cement with bleaching. Subjects were immersed in artificial saliva for 24 hours incubated at 37°C. All subject were thermocycled 500 cycle and then immerse in 2% methylen blue for 24 hours. Subject were sectioned in the middle of restoration longitudinally buccopalatal from coronal to apical. The microleakage was observed by looking at the length penetration of 2% methylen blue using stereomicroscope with 30 magnification. The data using scoring system, scor 0: no microleakage, scor 1: penetration up to one-third of the cavity depth, scor 2: penetration up to two-third of the cavity depth and scor 3: penetration more than two-third of cavity depth. The data were analyzed using a Kruskal-Wallis test with significancy 95% (α = 5%). The Kruskal-Wallis test shown that there was no effect of bleaching materials on microleakage class V restorations using resin composites and resin modified glass ionomer cements (RMGIC).
