Abstract
Flowable composites were released into the market with great expectations to address the drawbacks of packable composites, such as material adaptability. These materials can flow thanks to the low filler loading and high monomer content of these flowable composites, although frequently at the price of inferior physical qualities. It is generally acknowledged that a resin composite's mechanical behavior improves with increasing filler content, which in turn increases the restoration's potential longevity. As a result, resin composites with a very high filler content have arisen, and manufacturers may emphasize the filler content as a marketing point. However, one of the main techniques employed by manufacturers to increase the flowability of a resin composite is to reduce the filler content, which may have an impact on the mechanical properties of the material. Nonetheless, resin composites described as both flowable and having high filler content have been introduced. The color stability, surface roughness, and microhardness of resin composites have previously been found to be significantly influenced by parameters related to composition, filler size, weight, volume, thickness, polymerization quality, and polishing quality. In the current study, different flowable resin composites were immersed in different storage media to evaluate and compare their color stability, surface roughness, and surface microhardness. Additionally, the impact of these storage media on the mechanical properties of the tested composites was examined.
