[Adherence test in relation to caries activity].

Abstract

The amount of streptococcus mutans in saliva has been suggested as a way of estimating caries activity (Klock; Krasse, 1979; Newbrum et al 1984; Sabelli, 1985; Thylstrop; Fejerskov, 1988). This study was carried out no evaluate the relationship between an adherence test (formation of streptococcus mutans colonies which allows to group individuals according to level of risk) with the caries activity was determine in 137 children and samples of saliva (0.1 ml) were obtained from each of them. They were processed in mitis salivarius sucrose al 37 degrees C. during 48 hours. According to the reaching each child caries activity was recorded as percentage of non-active caries in the mean values in each group were statistically analyzed using Kramer's extension of Duncan's test. Significant differences were found only between high and low level risk groups. In the care of extreme groups the test seems to be valuable form estimation of caries activity.
