Abstract |
In this study, researchers tried to find the effect, if any, of aging treatment to the specimens with three different dentin bonding agents using MicroCT. One, 5th generation - [AdperTM Single bond Plus] and two 6th generation [AdheSE®, AdperTM PromptTM L-PopTM] dentin bonding agents were used in this study. Specimens were divided into 4 groups according to aging treatment method used. Group I : control group, Group II : thermocycled between 5℃ and 55℃ for 60 seconds dwell time 5,000 times, Group III : aged as Group II and artificially brushed 20,000 times, Group IV : aged as Group III and were stored in artificial saliva for 6 months. With Single bond Plus, Group II showed more microleakage than Group I (p < 0.05). Group II and Group III showed more microleakage than Group IV (p < 0.05). There were no statistically significant differences among the groups using AdheSE® and PromptTM L-PopTM (p > 0.05). Among Group I, AdheSE® showed more microleakage than Single bond Plus and PromptTM L-PopTM (p < 0.05). Among Group II, there were no statistically significant differences (p > 0.05). Among Group III, AdheSE® showed more microleakage than Single bond Plus and PromptTM L-PopTM (p < 0.05). Among Group IV, AdheSE® and PromptTM L-PopTM showed more microleakage than Single bond Plus (p < 0.05). |
