Type: article
Abstract: Purpose To investigate the impact of zirconium dioxide nanoparticles (nano‐ZrO2) addition to hard and soft liners on the surface roughness and Candida albicans adhesion. Materials and Methods Nano‐ZrO2 was added to hard and soft chairside reline material in two concentrations (2% wt. and 4% wt.) while an unmodified group of each liner acted as a control, (n = 10). Disc‐shaped (10 × 1.3 mm) specimens of hard denture reline (N = 60) and soft denture reline (N = 60) materials were prepared (30/test). A noncontact profilometer was used for surface roughness measurement. A colony‐forming unit (CFU/mL) was used to evaluate Candida albicans adhesion. Data was analyzed using ANOVA and a post hoc Tukey's test (α = 0.05). Results No significant change in surface roughness was observed with nano‐ZrO2 addition; however, the control groups showed the highest value while 2% nano‐ZrO2 showed the lowest value. In comparison to the control groups, nano‐ZrO2 addition to the hard and soft liners significantly reduced Candida albicans adhesion (p < 0.001), regardless of the concentration. Conclusion Incorporating nano‐ZrO2 into hard and soft liner had no effect on surface roughness while its addition reduced Candida albicans adhesion. Using chairside soft and hard liners containing nano‐ZrO2 is recommended to reduce the incidence of denture stomatitis (DS) among denture wearers.
