Influence of fat-free, fat and sucrose diets on rat periodont condition

Abstract

Aim. To investigate the effect of consumption of diets with different content of fat and sugar on the state of the periodontium of rats.Methods. The rats received a semi-synthetic fat-free diet (FFD), a fat diet (5 % sunflower oil), and a sucrose diet (50 % sucrose) for 30 days. Determined the degree of periodontal atrophy, tooth decay and in the gum homogenate - the activity of elastase, catalase, urease, lysozyme and the content of malondialdehyde (MDA).Results. Sugar diet increases the degree of periodontal atrophy and tooth decay, but decreases elastase activity in the gums and increases catalase activity. Fat diet does not affect periodontal atrophy and tooth decay, but it reduces catalase activity.Conclusion. The increase in the intensity of caries and periodontal atrophy under the influence of a sucrose diet is probably due to the stimulation of the formation of lactic acid. Fat nutrition does not affect the intensity of dental caries and the degree of periodontal atrophy.
