Fluoride‐releasing materials can be expected to inhibit the secondary caries. The aim ;of this study was to evaluate the effect of fluoride‐releasing adhesives on inhibition of secondary caries in outer and wall lesions. Two commercial fluoride‐releasing adhesives, Reactmer bond (RB) and One‐up bond F (OB), and a commercial adhesive without fluoride release, Mac‐bond II (MB), were used prior to placement of restorative materials without fluoride release, Lite‐fil II A (LF) and Estelite (EL), and a fluoride‐releasing restorative material, Reactmer paste (RP). Class V cavities prepared on extracted human premolars were restored with various combinations of the materials: MB/EL, OB/EL, RB/LF and RB/RP. The restored teeth were incubated in bacterial medium containing sucrose with Streptoccus mutans for 14 days. Microradiographs of specimens showed no wall lesions in all groups and an acid‐resistant layer adjacent to the restoration in the caries‐like lesion. OB/EL, RB/LF and RB/RP groups showed thicker layers than the MB/EL group. The RB/RP group formed the shallowest outer lesion among all groups. These results indicate that fluoride‐releasing adhesives are effective in the prevention of wall lesions but exhibit little outer lesion inhibition. Therefore, combined restoration using a fluoride‐releasing adhesive and fluoride‐releasing restorative material should be selected to inhibit secondary caries.
