The aim of this study was to analyze the antifungal activity and the general toxicity of a new dental gel containing essential oil from the tree Abies sibirica L., which grows in the Republic of Kazakhstan.
MATERIAL AND METHODS: The essential oil from Abies sibirica L. was obtained by microwave heating method using the STARTE Microwave Extraction System. Adjutants used to prepare the oil were carbomer 974P, glycerin, polysorbate 80, xylitol, triethanolamine, and purified water, all allowed for medical usage. The antifungal activity of the essential oil was assessed by monitoring the optical density of Candida albicans in a microplate reader. The safety was determined by analyzing the acute and subacute toxicity.
RESULTS: The essential oil obtained by the microwave heating method revealed a higher antifungal activity in comparison with the essential oil obtained by the steam distillation method. No obvious changes were detected in guinea pigs following cutaneous application of the gel. Enteral administration of the essential oil caused minimal functional and histological changes in mice after 4 weeks. The new harmless dental gel containing pine oil from Abies sibirica L. was provided for the purposes of this particular clinical research.
CONCLUSIONS: The high antifungal activity of the gel is the basis for more in-depth studies on its safety and pharmacological activity.
