Resumo: | The tackiness presented by resins brings inconveniences to the incremental technique, which can be improved by using lubricants in handling. Aim: To evaluate the influence of two adhesive systems as brush lubricants on the degree of conversion, translucency and intrinsic color stability of composite resins. Methods: Samples (n=10) were fabricated according to the composites (Filtek Z350 XT, IPS Empress Direct, and Esthet X HD), shades (bleach shade and A2), and lubricants used (Adper Single Bond 2, Scotchbond Multi-Purpose bonding agent, and no lubricant). Single composite increments were inserted into a Teflon mold. The composite surface was then modeled using a brush dipped in an adhesive system. The control group was fabricated with no additional modeling. The surface degree of conversion (DC) was measured using Fourier transform infrared spectroscopy; translucency and intrinsic color stability were accessed using a spectrophotometer. Data were analyzed using three-way ANOVA and the Tukey test (p<0.05). Results: Scotchbond Multi-Purpose decreased the DC of all composites and shades in comparison with the control group (p<0.05), although it did not decrease color stability (p<0.05). The bleach shade of IPS Empress Direct and Esthet X HD showed higher translucency than the A2 shade when lubricated with the adhesive systems (p<0.05). Conclusion: Therefore, the two tested adhesive systems used as brush lubricants on composites promoted changes to the surface degree of conversion and aesthetic properties. |
