[Evaluation of oral health status of a preschool group with a predictive test based on mutans group and clinical studies].

Abstract

A children's population, aged from 2 to 5 years, was studied for three years. Bacteriological and clinical criteria were followed, with a determination of the M. st level in non-stimulated saliva in the age-groups of 3, 4 and 5 years. We found, as Alaluusua did, a correlation between the M. st level in saliva and the number of caries. With this study, a large number of caries-free children had a low M. st level. The largest amount of caries appears in children with a high M. st level. The highest caries incidence in this population appears at the 4 year children group. It has to be remembered that this is an age-group with specific characteristics. Caries is a disease depending on many factors and the M. st level would be very significant to an early detection of risks, but should be evaluated considering all the parameters as a whole. Its predictive value is not sufficient by itself but it has an unquestionable value when detecting risk patients of an early age. Therefore, treatment has to be the result of an etiological diagnosis addressed to prevention after an evaluation of all the factors related with the caries disease.
