Abstract:
Composite resins Amaris is claimed to have hydrophobic
effect which minimizes the staining intake. This study is to investigate the colour stability of Amaris compared to Filtek Z250 in coffee
solution. Sixty discs of composite resins Filtek Z250 (3M ESPE) and Amaris (Voco) with diameter of 5mm and depth of 2mm were fabricated by packing in a drinking straw and sectioned with hard tissue cutter (Exakt, Japan). The surfaces of the specimens were
polished with Sof-Lex disc before each group of the samples is immersed in coffee solution. They were kept in the solution for 4 days at 370C and assessed at the period of 2 hours, 1 day, 2 days, 3 days,
and 4 days. The staining was assessed visually and recorded using Lobene (1968) Stain Index and score was given accordingly. The
colour changes of both groups were not statistically significant (p<0.05) for period of 2 hours, 1day, 2 days, 3 days and 4 days All groups showed the score values increased gradually with time. Both composite resins have similar colour stability in coffee solutions.
