| Abstract | ||
| Background: The purpose of this In-vitro study is to evaluate the effect of different polishing systems and dentifrices on discoloration of resin composite after immersion in tea staining solution followed by mechanical brushing. Methods: 42 Resin composite discs with 3mm thickness and 10mm diameter were prepared. Specimens were divided into three equal main groups, (n=14) according to polishing system used (Mylar strip, Sof-Lex, PoGo). The specimens were fully immersed in equal amounts of Black tea staining solution and incubated at 37ºC for 7-days. Each group was further subdivided in two subgroups according to the type of dentifrice used with mechanical brushing (N=7). Spectrophotometer was used to measure the color change after polishing, after staining and after brushing. The collected data was tabulated and statistically analyzed using two-way ANOVA. Results: Color change between groups was significantly difference after staining. The highest value was found with Sof-lex (2.95±0.18), followed by PoGo (2.75±0.17), while the lowest value was found with Mylar strip (2.41±0.15). Rapid white (5.20±0.45) had significantly higher color change than Colgate (4.83±0.44) (p=0.010). Conclusions: PoGo produced better surface quality in terms of color stability than Sof-Lex, whitening dentifrice was effective on removing Black tea surface stains than non-whitening. | ||
