Acid‐etching and bonding of composite resin to bevelled enamel margins has been reported to produce a reliable seal. However, achieving a seal with dentine and cementum margins is more difficult. Four different dentine bonding systems were used in combination with Silux composite resin to restore cervical cavities in vitro. None of the bonding systems used completely sealed either the occlusal or gingival margins. Of the four systems, GLUMA provided the best seal at both the occlusal and gingival margins.
