Methods: Sustained release varnish will be developed in our laboratory. The kinetics of release (using HPLC) and antifungal activity (Bioassays) will be examined in vitro. The formulation showing the optimal results will be tested on human subjects with oral candidiasis. The efficacy of the varnish will be examined clinically (reduction in symptoms), microbiology (reduction of oral fungal), pharmaceutically (release kinetics in vivo).
