Resumo
Os autores procuraram verificar a influência da cenoura (Daucus carrota), quando adicionada à dieta cariogênica para ratos, em relação ao número de S.mutans e a quantidade de placa bacteriana. Ratos com 20 dias de idade, divididos em três grupos, foram alimentados durante 90 dias com as seguintes dietas: os controles receberam ração triturada; o segundo grupo, dieta cariogênica; e o terceiro, dieta cariogênica contendo 18% de cenoura. A avaliação quantitativa revelou aumento de S.mutans nos animais alimentados com dieta cariogênica e dieta cariogênica contendo cenoura, em relação aos controles. Contudo, o aumento de S.mutans nos ratos alimentados com dieta cariogênica em relação à dieta cariogênica contendo cenoura não foi significativo. Apesar disso, a formação de placa bacteriana nos animais submetidos à dieta cariogênica foi mais intensa do que nos animais cuja dieta foi a cariogênica adicionada de cenoura.

Abstract
The influence of carrot, added to a cariogenic diet, in the amount of dental plaque and number of S.mutans was studied in the molar teeth of the rato Twenty days old rats were divided into three groups and fed with normal powdered diet, cariogenic diet and cariogenic diet containing 18% of carrot. The groups treated with cariogenic diet had a similar increase in the number of S.mutans in relation to the control group, independently of containing or not carrot. Animals fed with cariogenic diet containing carrot had more plaque than the controls, nevertheless the plaque index was significantly lower than that found in rats fed with cariogenic dietalone.
