Objective: The aim of the study was to evaluate the influence of different photoactivation times (10, 15, 30 and 60 seconds) on the sorption and solubility of adhesives Ambar, Scotchbond Multi-Purpose (SMP), Single Bond 2-SB (SB2), Single Bond Universal (SBU) and Ambar Universal (AU). Methods: Disks were made with each adhesive (n = 10). They were dispensed into 6.0 x 1.0-mm silicone molds and polymerized. The sorption and solubility values were obtained after 7 days of storage in distilled water at 37°C. Results: The results were analyzed by Kolmogorov-Smirnov, Kruskal- Wallis and Dunn’s tests at 5% of significance level. According to the results of sorption, the activation time factor showed no statistical difference (p > 0.05) compared to the other materials. For the solubility, statistical difference (p < 0.05) was found for SMP at 10s, 30s and 60s time. Evaluating the materials within the same activation time, SMP at 10s showed the lowest value of sorption and solubility, following these low values when activated for 15s and 30s. The highest solubility values were found for SB2, at 10, 15 and 30s. Conclusions: It can be concluded that the phenomena of sorption and solubility are closely related to the composition of the adhesive system and not to the time of photoactivation.
