Prior to marketing the CLEARFIL MAJESTY ES Flow series, Kuraray Noritake Dental had to prove that the material meets the standards of ISO 4049:2019 for polymer-based restorative materials in dentistry. Prompted by the positive response from users and its own confidence in the quality of the product line, Kuraray Noritake Dental asked the Nordic Institute of Dental Materials (NIOM) to test the dental composite filling material on key aspects of the ISO standard.

The voluntary testing of the series undertaken by the independent research institute thoroughly evaluated CLEARFIL MAJESTY ES Flow in all three levels of flowability: High, Low and Super Low (Fig. 1). Among the properties assessed were depth of polymerisation, flexural strength, water sorption and solubility, as well as colour stability after irradiation and water sorption. Across the different levels of flowability and the various shades, NIOM found that the properties of CLEARFIL MAJESTY ES Flow complied with the requirements of ISO 4049:2019. Kuraray Noritake Dental is pleased to have gone the extra mile and proud that an independent party has verified that its product meets the stringent ISO standards.
Implications for clinical use

The test results offer independent proof that the popular flowable composite series can be used safely as directed by Kuraray Noritake Dental. Regarding the depth of polymerisation, the NIOM test results demonstrate that the composite polymerises adequately when applied to the recommended layer thickness. This is essential for a reliable long-term performance. In addition, all three levels of flowability showed sufficient strength and water sorption and solubility behaviour, making them suitable for restorations, including for restoration of the occlusal surface of molars and premolars. This means that the materials are very well suited for a wide range of indications, such as restoration of all cavity classes, repair of existing restorations and cementation (Table 1).
Great aesthetics and handling

On top of these well-balanced mechanical properties, CLEARFIL MAJESTY ES Flow offers good handling properties, being easily dispensed from its innovative syringe for bubble-free application, easily sculpted thanks to its non-sticky formulation and easily polished. Available in a variety of shades (Fig. 2) and boasting proprietary light diffusion technology, the material in its three different levels of flowability blends nicely and effortlessly with the surrounding tooth structure, creating a natural overall look. Both handling and aesthetics have been rated as very good to excellent by dental adviser consultants in clinical evaluations.
NIOM also provided proof of the series’ positive aesthetic properties. The institute’s tests to evaluate colour stability after irradiation and water sorption demonstrated that the colour of CLEARFIL MAJESTY ES Flow remains stable over time. This feature is important for the long-term aesthetics of the restorations created with the materials.
The NIOM results demonstrate to dental professionals the importance of choosing a reliable, high-quality flowable direct restorative material that has been proved to withstand rigorous testing. Visit the Kuraray Noritake Dental website to learn more about CLEARFIL MAJESTY ES Flow.
