Popis: This study investigated the feasibility of a sustained-release delivery system for the treatment of denture stomatitis using four antifungal agents (chlorhexidine, clotrimazole, fluconazole, and nystatin) incorporated into a tissue conditioner (Lynal®) at zero (control), low, medium, and high concentrations. Hardness of all experimental groups increased with both concentration and time, but remained within the range of clinical acceptability (Shore A ≤ 49). Mean tensile strength increased in all experimental groups and was significantly stronger than the control for at least one concentration level of each drug, p ≤ 0.05. All failures for tensile-strength testing were characterized as cohesive. All drugs demonstrated release from the tissue conditioner matrix and inhibition of growth of C. albicans that was either total, dose-related, or related to incubation time prior to inoculation. All controls supported growth.
