MATERIALS AND METHODS  Cylindrical samples (15 × 1 mm) were made for each group using a metallic mold (n = 10). Vickers microhardness test was performed, and average hardness was calculated from three indentations (300 gf/15s) per sample. The sorption and solubility of the materials were evaluated according to ISO 40492009 based on three samples weighing initial (m 1), after immersion in distilled water for 7 days (m 2), and final (after removal of all moisture [m 3]). The color change was observed using a digital spectrophotometer, at three different time points, baseline, 1 day, and 1 week of immersion in coffee and distilled water (control). STATISTICAL ANALYSIS  Shapiro-Wilk test was used to analyze the normality of the data, and groups were compared using Kruskal-Wallis and Mann-Whitney tests. A significance level of 5% was used. RESULTS  RLX showed the highest microhardness mean values (36.96 VHN), but higher sorption (23.2 µg/mm3) and solubility (2.40 µg/mm3), with statistically significant differences with the other groups. For color stability, higher ∆E was observed for the samples immersed in coffee (p = 0.009). The VLK resin cement presented statistically significant differences from the other groups, with higher color changes in coffee at 1 day (15.14) and after 1 week (23.65). CONCLUSION  RLX resin cement showed better hardness results. All materials tested performed satisfactorily for sorption and solubility according to ISO 40492009. All materials showed high-staining values after 1 week of immersion in coffee.OBJECTIVE  Dental pulp stem cells (DPSCs) can be used as a component in the formation of regenerative dentine during direct pulp capping therapy.
