摘要
Abstract
Objective: Evaluate the microleakage of resin-modified glass ionomer adhesive (GC). The aim of this study was to provide evidences for clinical chose of Orthodontic Adhesives. Method: 24 freshly-extracted human premolars were divided to Al and A2. Group Al, resin adhesive (3M); groupA2, resin-modified glass ionomer adhesive (GC). The teeth subjected to 2000 thermal cycles. After stained with 0.5 % basic fuchsin for 24 hours, sectioned,and photographed under a low power stereomicroscope. At last the interface of enamel-adhesive was obsvered under SEM. Result: GC results in more microleakage than 3M in both tooth-adhesive and bracket-adhesive interfaces. A significant difference was observed. Con-clusion: More microleakage of GC needs take into consideration when ues in orthodontic pradices.关键词
