Abstract

Objective: This study measured the color change of lithium disilicate (E. max CAD), micro-hybrid resin composite (Coltene C bright, Filtek Z250) and feldspathic ceramic (Vita Mark II) laminates after putting them in coffee, Cola and artificial saliva staining solutions for seven days. Materials and Methods: Sixty freshly extracted sound upper central incisors were randomly divided into four groups (n=15) according to the material used for laminate veneer fabrication; E. max CAD (Group I), VitaMark II (Group II), Coltene C Bright blocks (Group III ) and Filtek Z250 composite resin (Group IV). Teeth were all prepared to receive a prepared sample of a squared-shaped laminate of different materials in a dimension of 7x7 mm. Cementation, finishing and polishing procedures were performed followed by color change measurement using a spectrophotometer. Measurements were all recorded before and after immersion for seven days. Results: Time, material type and immersion medium had a statistically significant effect on mean color change (p<0.001). Intra-group comparisons displayed that E. max CAD showed the lowest color change, whereas Coltene C bright blocks were the greatest to show color change. Vita Mark II showed a higher color change in artificial saliva than Filtek Z250, however, the latter demonstrated a surpassing change in color in the other solutions. Conclusion: Material type, external source of stain, and staining time are important factors that affect the degree of color change, which in turn could affect patient satisfaction. E. max showed the best results in all solutions regardless the exposure time.
