Effect of two surface sealants on color alteration of a composite resin

Tatiana Kelly Silva Fidalgo, Ivo Carlos Correa


Objective: To evaluate the alteration of color (DE) among surfaces treated with liquid finish and polish system. Method: Was used Fill Magic (Vigodent ® , Rio de Janeiro, Brasil), A2
(n=18) and A3.5 (n=18) composite resins. The specimens were polymerized, and was registered L*a*b* values using a colorimeter, then two surface sealants was applied: BisCover ™ LV (Bisco Inc, Schaumburg, USA) and Fill Glaze (Vigodent ® , Rio de Janeiro, Brazil) and was registered L*a*b* values. For the control group was not applied surface sealant, and L*a*b* values was registered in two different moments. The DE ab* values were submitted to the analysis of variance (ANOVA) and then to the Tukey test. Results: Was not observed color alteration using BisCover TM LV in both resins A2 and A3.5 (p>0.05). However, was observed color alteration when was used Fill Glaze, in both resins A2 and A3.5 (p=0.021 and p=0.002, respectively). Conclusion: In two tested composite resins colors, the surface sealant BisCover TM LV presented no color alteration, ideal to application in esthetic restoration, when the color should be maintaining.
