Riesgo Biológico de Caries en Ni？os con Sindrome de Down entre 12-17 A？os del Cavime, Concepción, A？o 2010

the aim of this research was to determine the biological risk cariogenic in subjects with down syndrome. a sample of 8 individuals between 12 and 17. clinical examination was performed on each subject, which evaluated different factors of caries in the oral cavity, in addition to laboratory tests for characteristicsof saliva and dietary surveys to parents. among the factors discussed in the oral cavity, we find, diastema, history of caries, among others. in laboratory tests a count was determined of streptococcus mutans and lactobacillus, ph and buffer capacity. counts of both bacteria, the initial ph and buffer capacity, corresponded to a low cariogenic level. after analyzing all the factors to be evaluated it was concluded that children with down syndrome studied have a low cariogenic biological risk.
