The Effect of Five Disinfection Methods on Candida albicans-Infected Chair-Side Soft Liners: A Comparative In Vitro Study
Main Article Content
Abstract
Background: Soft-liners, particularly used for patients with poor hygiene habits, can become a favorable environment for the aggregation of microorganisms. Therefore, disinfection is considered a critical process for preserving the health of oral mucosa. This study aimed to determine the antifungal efficacy of five different disinfectant methods on silicone resilient lining materials.
Material and Method: A total of 60 test samples were prepared and inoculated with 2 ml of Candida solution and incubated for 2 hours. The inoculated specimens were then randomly divided into six groups (n=10): Control group, 0.5% sodium hypochlorite (NaOCl) group, Corega® denture cleansing tablet group, microwave water group, diode laser group, and 4% iodine solution group. A swab was taken from the surfaces of the soft-liner discs in each group, planted on aerobic culture media, and the colonies were counted separately for each treatment.
Results: A significant difference (p < 0.05) in inhibiting the growth of Candida albicans was observed with all five types of disinfection methods compared to the control group.
Conclusion: According to the results, the iodine group and the laser group demonstrated the best disinfection effects, respectively.
