The introduction of adhesive techniques and new materials gradually change operative dentistry. Self-etching primers are widely used in permanent teeth, as well as in primary teeth, under composite and compomer materials. The aim of the study was to investigate the resin-dentine interface of an adhesive system Clearfil SE Bond (Self-etching primer + bonding agent, KURARAY) in primary teeth using High Resolution Scanning Electron Microscope. Freshly extracted caries-free human deciduous molars were used in the study. Standard class V cavities were restored using Clearfil SE Bond according to the manufacturer"s instructions. Adhesive was also applied upon total etching for 15s by using a 10% poly-acrylic acid, as a different protocol. Teeth were then restored with Compoglass F (VIVADENT) compomer restorative material. The interface images of the specimens, micro-morphologically analyzed by SEM, showed that the Cleartil SE Bond, as a dentine adhesive system, had a homogenous hybrid layer, and also exhibited similar characteristics regarding resin penetration in deciduous teeth. When poly-acrylic acid conditioning was applied, the smear plugs were removed. The total etching technique revealed open tubules and resin tag formations. Micro-porosities were filled with resins and thus revealed a good adaptation of the compomer to enamel. It was concluded that Clearfil SE Bond as dentine adhesive system could be used successfully under compomer restorative materials in primary teeth. However, removal of the smear plugs by poly-acrylic acid etching could further improve the adhesion to dentin and enamel.
