Clinical Cases, Chairside Treatment of primary caries in a third molar 16 Feb 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.

Clinical Cases, Chairside Clinical case with CLEARFIL MAJESTY™ ES-2 Universal shades 10 Nov 2020 By Dr Luca Dusi For purely aesthetic reasons, this patient asked for the reconstruction of her cone-shaped upper right lateral incisor (12). The patient was offered a treatment including a first phase of orthodontic therapy aimed at recovering the space necessary to be able to reconstruct the lateral incisor to its ideal size. As the patient refused to undergo this orthodontic therapy, it was decided to restore the tooth with resin composite and match its size to the space already available. The adhesive system used was CLEARFIL™ SE BOND 2, while the restoration was created with the new composite CLEARFIL MAJESTY™ ES-2 Universal. Although this material is designed for the single-shade technique with only two shades matching the anterior tooth shades, I decided to combine both pastes to achieve the best possible outcome. The shade UD (Universal Dark) was used to reconstruct the cervical and central portion of the lateral incisor. The incisal portion was restored with UL (Universal Light). Fig. 1.

The new CLEARFIL MAJESTY™ ES-2 Universal composite with only two shades for the anterior region was chosen. It offers a good optical integration thanks to Kuraray Noritake Dental’s Light Diffusion Technology. Fig. 4.
