Staining susceptibility of recently developed resin composite materials
Journal Title: Journal of Clinical Advances in Dentistry - Year 2018, Vol 2, Issue 1
Abstract
Objectives: To evaluate the colour stability of 3 recently developed resin based materials continuously exposed to various staining agents. Methods: 144 disc-shaped specimens were made of each of the 3 tested composites (Essentia, Brillant, Inspiro). Half of them were of 1mm thickness, the other half 1.2mm thickness. The thicker group was than polished up to 4000 grit and reduced to 1mm thickness, too. All specimens after 24 h dry storage in an incubator (INP-500, Memmert), received an initial colour measurement by means of a calibrated reflectance spectrophotometer (SpectroShade, MHT, Niederhasli, Switzerland). Specimens were then divided into 6 groups (n=6) and immersed in 5 staining solutions or artificial saliva (control). All specimens were kept in an incubator at 37°C for 28 days. Staining solutions (red wine, curry mixed water, curry mixed oil, tea and coffee) were changed every 7th day to avoid bacteria or yeast contamination. After 28 days of storage spectrophotometric measurements were repeated and L*a*b* scores once more recorded to determine the colour (ΔE00) changes.
