Objective To test and compare the color and translucency between the mono-component light-cure adhesive resin and try-in paste with same number for porcelain veneer restorations, and evaluate the consistency of the materials. Methods Variolink Veneer and Relyx Veneer were involved in the study.The adhesive resins and try-in pastes were added into a model of diameter of 10 mm and thick of 2 mm with white background and covered with filtered cover glass, and then the resins was cured with light. The color ( L* , a* , b* ) of these samples was test and △E was also calculated to evaluate the color consistency of samples. The resins and try-in pastes were made into a thin layer of 0. 15 mm, and their translucency was tested under the light from 380 μm to 780 μm. Average translucency was calculated. Tukey t-test for multiple comparisons was used to analysis the differences of △E. Paired t-test was used to analysis the differences of translucency of them. Results Tukey's t-test shows that the evaluation of AE of TR ( 1.11 ±0. 18) was a; those of LV-1 (6. 38 ±0. 45), LV-2(5.94 ±0. 19), A1 (7. 54 ±0. 20), WO(4. 24 ± 1.14)were b; those of HV +2(10. 90 ±0. 41), HV +1(11.48 ±0. 17), LV-3( 10. 69 ±0. 13), B0. 5( 13.26 ±0. 21 ) were c; and those of HV +3(21.94 ±0. 21 ), MV0(29. 78 ±0. 14), A3(32. 67 ±0. 19) were d(a,b, c, d meaned that the consistency of resin and try-in paste became lower and lower). There were significant differences between resin and tray-in paste in 7 colors(A1, TR, HV +3, HV +2, HV +1, LV-2, LV-3) of 12 colors(P ＜ 0. 01 ). Conclusions The consistency of color and translucency between most adhesive resin and try-in paste with same number is low. This kind of materials should be used with caution in demanding cases.
