ABSTRACTThe use of natural products in Dentistry has been shown as an alternative source against oral diseases, including fungi infections, generally caused by Candida spp. The aim was to evaluate the antifungal action of tinctures from propolis (Apis milifera) and from pomegranate (Punica granatum) on Candida albicans (ATCC 76618), Candida krusei (ATCC 6538) and Candida tropicalis (ATCC 13803). The antifungal activity of tinctures was evaluated by Minimum Inhibitory Concentration method on Saburaud Dextrose Agar (Difco®). Six wells were confectioned, with 6 mm of diameter, to the insertion of 50 µL of tinctures. Six serial concentrations were evaluated, been 200 mg/mL the initial concentration for tincture from propolis and 300 mg/mL the initial concentration for tincture from pomegranate. Later, the Petri plates were incubated in bacteriological incubator for 48 h on 37 ºC. Data analysis for Minimum Inhibitory Concentration was conducted by measurement of inhibition zones, been considered inhibited when equal or bigger than 10 mm of diameter. For tincture from pomegranate, was verified that the Minimum Inhibitory Concentration on Candida albicans, Candida krusei and Candida tropicalis were 9.37 mg/mL, 9.37 mg/mL and 18.75 mg/mL, respectively. For tinctures from propolis, the antifungal action was verified only in pure concentration on Candida krusei and Candida tropicalis, but it was not observed on Candida albicans. The tinctures from pomegranate and propolis had antifungal activity on evaluated strains, except for tincture from propolis on Candida albicans.
