Clinical Cases, Chairside Replacement of an amalgam restoration in a maxillary first molar 11 de mar. de 2021 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. Fig. 1.

Clinical Cases, Chairside Treatment of primary caries in a third molar 16 de fev. de 2021 Case by Dr. Michał Pokojski When restoring primary carious lesions in the posterior area with composite, I wish to use a material that allows me to produce high-quality outcomes in an efficient procedure. The most important qualities of the restoration are its perfect marginal integrity and reliable long-term behaviour, which set the stage for a long and healthy life of the otherwise healthy tooth. Reliability paired with ease of use is what I expected from the selected material combination: CLEARFIL™ SE Bond 2, a popular self-etch adhesive containing the original MDP monomer, and CLEARFIL MAJESTY™ ES-2 Universal. According to Kuraray Noritake Dental, the innovative resin composite comes with a universal shade concept and mechanical properties such as shrinkage, wear resistance and colour stability similar to those of proven CLEARFIL MAJESTY™ products. As a single shade is available for the posterior region, the need for shade determination is eliminated, which allows the dental practitioner to focus on the clinical work steps. In this case, a small primary defect in a third molar was restored. The outcome speaks for itself. Fig. 1. Situation during cavity preparation revealing the carious lesion. Fig. 2.
