Abstract
Objectives: The aim of this study was to evaluate in vitro color stability of resin ceramic and feldspathic porcelain with two different mouth rinses: non-alcohol based 0.12% Chlorhexidine digluconate (CHX), and alcohol-based Listerine®.
Methods: Two types of CAD/CAM ceramic-blocks: Hybrid resin ceramic (VITA ENAMIC® for CEREC®/ inLab®, VITA Zahnfabrik H. Rauter GmbH & Co.KG., Germany, VE) and Feldspathic (Vitablocks MarkII, VITA Zahnfabrik H. Rauter GmbH & Co.KG., Germany, VM) were included in the study. A total of 36 samples of each material were prepared. Groups VE and VM were divided into three subgroups (n = 12 per group) based on the immersion medium: distilled water (control, W), non-alcohol-based mouth rinse, 0.12% Chlorhexidine digluconate (NA), or alcohol-based mouth rinse (A), Listerine®. Samples were stored in 20 mL in one of the mouth rinses for 120 hours, which was reported as the equivalent time to 10 year of 2-min daily mouth rinse use. Samples’ baseline color values were recorded according to the CIE Lab system by using a color spectrophotometer. Color measurements were subsequently obtained following immersion for 120 hours and after samples rinsing with distilled water and allowed to dry. CIE L*, a*, and b* were measured. Color difference (ΔE), were calculated and analyzed using one-way ANNOVA (P<0.05).
Results: Immersion in either Non-Alcohol, or distilled water resulted in significantly higher color change values for VE compared to VM, while no significant difference in color change existed between both materials following immersion in Alcohol based Listerine mouth rinse.
