doi: 10.1111/j.1741‐2358.2010.00438.x Evaluation of experimental cleanser solution of Ricinus communis : effect on soft denture liner properties Objective: This study evaluated colour stability, hardness and roughness of soft denture liners after immersion in various cleansers. Materials and methods: Thirty specimens (14 mm × 4 mm) of Elite Soft Relining (ES) and Mucopren Soft (MS) were randomly immersed in distilled water at 37°C, sodium hypochlorite 1%, and an experimental Ricinus communis solution (RC) for 7, 15 and 183 continuous days. Results: anova ( p < 0.05) and Tukey’s test indicated that after T7 ( μ =8.79 ± 7.36); T15 ( μ = 4.23 ± 2.62) and T183 ( μ = 8.78 ± 3.16), MS presented a higher increase in hardness than ES. After T7, MS underwent an increase in roughness ( μ = 0.09 ± 0.80); ES underwent a decrease ( μ = −0.08 ± 0.16). RC caused the smallest variation in roughness. After T15, both materials presented an increase in roughness. After T183, ES ( μ = −0.30 ± 0.48) presented a higher roughness variation than MS ( μ = −0.07 ± 0.32). Hypochlorite caused an increase in roughness ( μ = 0.02 ± 0.19). Conclusion: After all periods ES presented higher colour alteration than MS; highest colour alteration was caused by hypochlorite. Both materials were more stable after immersion in RC.
