Effect of Denture Cleansers on Color Stability of Different Acrylic Resin Materials
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 12
Abstract
Objective: The objective of this investigation was to assess the effects of different denture cleansers and distilled water on color stability of self-polymerized (SP) and heat-polymerized (HP) acrylic denture base materials. Methods: Specimens were prepared from HP (Lucitone 199) and SP (Rapid Repair) acrylic resin denture base materials and distributed into different groups/15 each. Specimens were immersed in distilled water as control and in three different denture cleansers (Corega, Polident, and StainAway Plus) according to the manufacturer's specifications and immersion was repeated 7 times over 7 days. All specimens in different groups were measured for color stability using a spectrophotometer against a white background under a standard illumination of D65. Statistical analyses were performed using one and two-way analysis of variance and independent t-test. Results: No significant color change in HP acrylic base material immersed in denture cleansers compared to the control group (P=0.531). However, a significant change in the color was found in SP resins (P=0.000). A significant increase in color change for SP resins immersed in Corega (ΔE = 5.300 ± 2.94) and Polident (ΔE = 6.167 ± 2.80) compared with the control group (ΔE = 2.753 ± 1.35) (P<0.05). A statistically significant lower color change was recorded after immersion in StainAway Plus compared to Corega and Polident (P<0.05). There was a significant increase in (ΔE) for SP resins immersed in Corega and Polident compared to HP resins (P<0.05). Conclusions: Short-term immersion of acrylic denture base materials in denture cleansers showed significant color change of self-polymerized compared to heat polymerized acrylic resins. Immersion of self-cure acrylic reins in Polident and Corega denture cleansers produced appreciable color changes compared to a slight change after immersion in StainAway Plus.
