Abstract

Purpose of this in vitro study is Recognition the effect of using of the miconazole gel opposing two forms of improving denture retention materials (Zinc-free Polygrip cream and Snug denture soft cushion) on their retention strength.
Materials and method: Eight heat cured acrylic samples were prepared having equal dimension flat tested surface. Two well adapted tested surfaces were matched and fixed to universal testing machine clamp. Vertical separating load was applied in a rate of 1mm/min to measure maximum load before failure of denture adhesive. These measurements were used to express the retention strength when improving denture material was used alone or opposed by miconazole nitrate gel.
Result and Conclusion: The mean difference of tensile strength showed significant reduction when antifungal gel opposed the two denture adhesive forms. Snug denture cushion showed higher retention strength when used alone or opposed by miconazole gel when compared with zinc-free Polygrip cream.
