Abstract
Adhesive cements (that chemically adhere to both the tooth and the restoration material) are considered to be a highly specialised group of composite cements. They involve a three-step procedure (acid etching, bonding agents or silane and composite resin), like cements using acid etching technique and have similar physical properties as the latest. The purpose of this study was to statistically analyse the values of the adhesive bond between dental tissue and ceramic, using three types of cements (both commercial products and a product from Romania) and one type of ceramic. The separate combinations were studied in order to identify the weakest link of the interface of dental-tissue-ceramic in terms of shear bond strength. The adhesion values recorded at the interface of cement-enamel for Dualcim and Nexus cements were significantly different from those recorded for Variolink cement. The highest resistance to adhesion was recorded to the interface cement Variolink – dentin, the average being 16.19 MPa.
