Replacement of an amalgam restoration in a maxillary first molar

Case by Dr. Michał Pokojski

Universal resin composites with a simplified shade concept are popular as they streamline direct restoration procedures. Unfortunately, many of the available products that claim to blend in well with the surrounding tooth structure independent of its shade need a blocker or opaquer to mask dark areas. According to Kuraray Noritake Dental, CLEARFIL MAJESTY™ ES-2 Universal is different. This is why I decided to test its Universal shade (U) designed for all kinds of restorations in the posterior region in the context of replacing an amalgam restoration.

The restoration that needed to be replaced due to secondary caries was located in the maxillary molar region of a male patient. As usual under amalgam restorations, the remaining healthy tooth structure showed some discolouration. The cavity was prepared, the enamel etched and the whole bonding surface treated with CLEARFIL™ SE Bond. Subsequently, the restoration was built up using CLEARFIL MAJESTY™ ES-2 Universal in several layers. For a natural appearance, some brown tint was added to the fissures before finishing and polishing. The restoration shows a natural integration into the surrounding structure and is able to mask the discolouration on the cavity floor.
