Marginal quality provided by Prime&Bond XP in dentin was better than one of the two tested adhesives (Figure 34). Summary of data on marginal quality of direct restorations Prime&Bond XP not only offers a very good seal of the margins in enamel and dentin but provides an exceptional seal of dentin, too. Marginal integrity of luted ceramic inlays Marginal integrity with and without curing the adhesive (, ) Practitioners very often hesitate to light cure the adhesive when luting indirect restorations because of possible interference of pooled and cured adhesive with the fit while seating the restoration for luting. For systems including high viscous bonding materials (e.g. Heliobond) the respective manufacturer recommends not to cure the adhesive because of this reason. It was evaluated whether curing the adhesive layer in the case of Prime&Bond XP had any influence (Prime&Bond XP SCA (LC)). Figure 35 Perfect margins of adhesively ceramic inlays It could be demonstrated that Prime&Bond XP and SCA when using Calibra classic as cement performs equally well with and without being light cured before seating the restoration. Micro-Morphology In order to illustrate and understand the interaction between adhesive and tooth substance specimens were investigated using FESEM, TEM and light microscopy. FESEM and TEM investigation Since etching of dentin with phosphoric acid was introduced one focus of research has been the question whether the demineralized collagen network can be infiltrated
