Abstract
Objective: To investigate color stability of four provisional restorative materials after immersion in different staining solutions at various immersion time.
Materials and methods: Four provisional restorative materials were selected, namely, methacrylate resin (Unifast Trad) and bis-acryl resins (Protemp 4, Luxatemp Fluorescence and Integrity). Twenty-one disc shaped specimens (15 mm diameter, 1 mm thick) were prepared from each provisional restorative materials according to the manufacturer’s instruction. Seven specimens of each material were randomly assigned for immersion in distilled water (control), coffee and curry. All specimens were stored in the solutions at 37°C. According to CIELAB system, the color baseline was measured with the spectrophotometer. The color change (∆E) was measured after immersion for 7, 30 and 90 days. Data were analyzed statistically with two-way repeated analysis of variance and multiple comparisons.
Results: Distilled water (control): All provisional restorative materials had no statistically significant difference in mean color change at day 7 (p>0.05). At day 30, color change of Unifast Trad (∆E30=1.5±0.18) was significantly higher than Luxatemp (∆E30= 0.80±0.52) (p<0.05). At day 90, Unifast Trad (∆E90= 3.58±0.29) showed significantly higher color change than others (p<0.05). Coffee: All provisional restorative materials had no statistically significant difference in color change at day 7 and 90 (p>0.05), except Integrity (∆E7= 11.93±4.69), (∆E90= 21.80±3.88) which had significantly higher color change (p<0.05). At day 30, Integrity (∆E30= 15.81±4.17) showed significantly higher color change than Luxatemp (∆E30= 11.53±2.91) and Unifast Trad (∆E30= 10.39±1.10) (p<0.05). Curry: All provisional restorative materials had no statistically significant difference in color change at day 7 and 30, except Unifast Trad (∆E7=6.14±0.98), (∆E30=9.32±3.17) which had significantly lower color change (p<0.05). At day 90, Unifast Trad (∆E90=24.41±3.37) showed significantly lower color change than others (p<0.05).
Conclusion: The type of provisional restorative materials, staining solutions and immersion time could affect the color stability of provisional restorative materials.
