[Follow-up studies on 15-month-old adhesive fillings].
Clinically, 450 Adhesive Restorations have been reexamined 15 months after insertion. Several of these restorations were also evaluated by SEM. The principles of cavity preparation for adhesive fillings deviate from those postulated by G.V. Black. They aim at a micromethanical retention of the restorative material to the tooth structure. A considerable amount of sound tooth structure can be saved. The combination of cavity design with enamel conditioning and the use of a low viscosity sealant prior to the insertion of the composite (Caulk Nuva System) resulted in restorations showing no microleakage and a perfect marginal adaptation. Their retentive strength seems to be sufficient as well as the durability of their excellent marginal properties. Pulpal responses to the application of etching agents were avoided by covering the dentin with an acid resistant base. Splinting of teeth using a strictly adhesive method without cavity preparations failed in more than 50%. The high rate of composite discoloration (43%) was probably due to factors inherent in the restorative material itself.
