The authors’ aim was to investigate the effectiveness of self‐etch adhesives used as surface coating agents on the microleakage of conventional and resin modified glass ionomer cements. A total of 120 class V cavities were restored with either Fuji IX or Fuji II. Specimens were divided into six groups for each material according to surface coatings: uncoated, G‐Coat, Futurabond, One‐Coat, Clearfil S3 and Xeno III. The specimens were immersed in basic fuchsine, sectioned and scored for microleakage. Results were analysed with Kruskal–Wallis and Mann–Whitney U tests. For Fuji IX, no microleakage was observed at the occlusal margins with any of the coating materials tested, and microleakage at the gingival margins was lowest with One‐Coat. For Fuji II, no microleakage was observed at either the occlusal or gingival margins for any of the materials tested. Self‐etching adhesives may be used as a surface coating to reduce marginal microleakage of glass ionomer restorations.
