International Arab Journal of Dentistry
Introductions: The increasing consumption of acidic beverages has raised concerns regarding their impact on the longevity of composite resin restorations. Surface microhardness is a critical parameter for evaluating the mechanical performance and durability of restorative materials.
Aim: To evaluate and compare the effect of beverages with varying acidity on the surface microhardness of different composite resin materials and to assess the relationship between beverage pH and microhardness reduction.
Materials and Methods: This in vitro experimental study included 140 disc-shaped specimens of four composite resins: Filtek Z350 XT, Tetric N-Ceram, Beautifil II, and Charisma Smart (n = 35 …
