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 ΔE 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 ΔE. Paired t-test was used to analysis the differences of translucency of them. RESULTS Tukey's t-test shows that the evaluation of ΔE 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.
