Evaluation of Activa BioActive-restorative Flexural Strength in Comparison to Traditional Composite Resin, Glass Ionomer, and Resin Modified Glass Ionomer
Abstract
Objective: The objective of this project is to assess the relative flexural characteristics of four commercially available restoration composites. Methods: Forty samples each of ACTIVA BioACTIVE-RESTORATIVE, GC Fuji II LC resin modified glass ionomer, GC Fuji IX GP EXTRA glass ionomer, and 3M Filtek Supreme Ultra restorative resin composite, were prepared for flexural testing according to ISO 4049:2000 (E) 7.11 Flexural Strength Class 2 Group 2 materials. Samples were subjected to a 3-point bending test using Instron 5943. Flexural characteristic data for the samples were calculated and subject to analysis of variance followed by post hoc testing to elucidate pairwise differences. Results: Of the four tested composites, 3M Filtek Supreme Ultra had the highest flexural modulus (M=653.69 N/mm2, SD = 257.36), indicating it to be the most rigid of the groups, P<0.001. In contrast, ACTIVA BioACTIVE-RESTORATIVE displayed significantly higher deformation tolerance with nearly twice the mean flexural strain at maximum load compared to the other groups, P<0.001. Significance: Constant change and development of dental materials to reach restorative needs of the patient and dentist are necessary for accurate care. Continued studies on strengths and physical properties of materials should be continued to ensure the most appropriate materials are being utilized.
