CLEARFIL MAJESTY™ ES Flow Universal In Vitro Evaluation
By Margaret A. Gilmartin, BS, and Taiseer Sulaiman, DDS, PhD/09.19.26
This study compared the flowable composite resin, CLEARFIL MAJESTY™ ES Flow Universal, with a leading competitor and demonstrates the fundamental mechanical properties and handling superiority found with Kuraray’s material. CLEARFIL MAJESTY™ ES Flow Universal exhibits higher flexural strength (160 MPa vs. 128 MPa) and compressive strength, providing a robust structural foundation that the competitor lacked. Furthermore, CLEARFIL MAJESTY™ ES Flow Universal’s no-slump viscoelasticity provides positional stability, and its engineered tip design minimizes the risk of incorporating voids. Diagnostically, CLEARFIL MAJESTY™ ES Flow Universal offers ideal contrast (230% aluminum equivalence), whereas the lower radiopacity of the competitor (140% aluminum equivalence) can present a diagnostic safety risk. Collectively, the data confirms that CLEARFIL MAJESTY™ ES Flow Universal shifts the flowable category from a limited liner material to a highly durable and diverse mode of restorative application.
