Statement of the Problem: The treatment of oral candidiasis, involves adjusting the old prosthesis, use of temporary soft denture liners and initiation of anti-fungal therapy. However, due to lack of patient’s compliance, copious amount of saliva and increased evidence of drug resistance, there is a need for an improved drug and drug delivery system.

Aims: Assess the antifungal efficacy of two different brands of modified denture liners (Visco gel-Dentsply and Soft denture liner-GC) containing silver zinc zeolite towards Candida albicans.

Methods and Material: The mean inhibition diameter (MID) was used to test the antifungal efficacy of 2% SZZ and 5% fluconazole in two commercially available soft denture liners: Visco gel and GC. MIDs were measured at day 1, day 3, day 7 and day 15, while carrying out the monitoring daily. Data was statistically analysed using one way ANOVA and post hoc Bonferroni test.

Results: 2% w/w SSZ in GC soft denture liner was found to be the most effective (p < 0.001).

Conclusion: Within the limitations of the study, it can be concluded that SZZ and fluconazole mixed with denture liners can be used against C. albicans. 5% fluconazole is the recommended choice for short term antifungal efficacy, while 2% SZZ is recommended when prolonged antifungal efficacy is indicated. GC soft denture liner was the recommended choice in both these cases.
