    Objective: To evaluate the color stability, surface roughness, and microhardness of dental restorative materials in various pediatric liquid drugs (PLDs). Material and Methods: A total of 175 restorative material discs were prepared for the following groups (n=25): Filtek Ultimate (FU), ACTIVA BioACTIVE Restorative (AC), ADMIRA Fusion X-tra (AD), Beautifil II (BII), Equia Forte (EQ), Fuj & imath; II Lc (FII), Fuji IX (FIX). After the initial colour assessment was performed, surface roughness and microhardness values were measured. Specimens were divided into five subgroups (n = 5) for each test, including Aerius, Ferrosanol, Atarax, Keppra, and Ventolin. Measurements were repeated following a 4-week immersion cycle. The resulting data were analyzed statistically using the Shapiro-Wilk, Kruskal-Wallis, and Friedman tests. Results: The FII group showed the highest Delta E. However, there was no significant difference between the BII and EQ groups (p>0.05). The Ferrasanol B caused the most significant color change in materials (p < 0.05). The Ventolin significantly increased the surface roughness of the materials (p < 0.05). Following the PLD storage, the surface roughness of the BII and FIX groups increased, while the microhardness of the FU, BII, EQ, and FII groups decreased (p < 0.05). The Aerius, Atarax, Keppra, and Ventolin significantly disrupted the microhardness of the materials (p < 0.05). Conclusion: Pediatric liquid drugs may cause unfavorable effects on the color stability and surface properties of restorative materials.
