BackgroundColor change of dental materials over time because of staining agents has important effects on the long-term prognosis of dental esthetic treatments. In the present study, staining resistance of an interpenetrating network composite material with different translucency levels (translucent and high translucent) and various surface procedures for finishing were investigated.MethodsSame shade CAD/CAM interpenetrating network composite specimens having two different translucency levels were prepared using by a water cooling cutting saw. Specimens were grouped and different finishing procedures were performed. Then, specimens were kept in distilled water, red wine and coffee for different periods. Color was evaluated before and after exposure to staining liquids using a clinical spectrophotometer.ResultsIn the 7days Glaze group (E-00>2.2), color difference was only perceivable in the specimens kept in red wine. In the 28days red wine high translucent groups, only the high translucent Clinical group showed a clinically acceptable (E-00<2.2) color change. In the translucent groups kept in red wine, only the translucent Glaze group showed a clinically perceivable color change (E-00>2.2). In the 28day measurements, all the translucent groups showed a clinically perceivable color change (E-00>2.2). Of the translucent groups kept in coffee for 28days, it was observed that only the translucent Clinical group demonstrated a clinically non-perceivable color change (E-00<2.2).ConclusionsAll the translucent groups kept in red wine showed a clinically perceivable color change after 28days. Only the high translucent Clinical Kit group showed a clinically acceptable color change. Among high translucent and translucent specimens kept in coffee only the translucent Clinical group showed a clinically acceptable color change after 28days.
