[Streptococcus mutans: its relation to cariogenic activity].

This research was carried out with the purpose of learning about relationship between degree of infection by Streptococcus mutans in saliva and prevalence of caries and further incidence in a one year term. A total of 931 children aged 2-3 years of Havana City and Sancti Spiritus Province, and 10 different series of school children aged 6-12 years of both provinces, with a total of 848 children, were studied. A direct significant relationship between degree of infection by S. mutans and prevalence of caries (percentage of affected children and co/COPD index) was found in the groups under study. Likewise, in the relationship between previous degree of infection and incidence of caries, differences were significative in children aged 2-3 years and in six of the 10 series of school children, with a correlation (r) of 0.216. It is analyzed that despite that degree of infection by Streptococcus mutans is the parameter with higher correlation with cariogenic activity, its predictive value is not enough by itself, therefore, a joint valuation with other parameters also related to cariogenic activity is required, in order to be able to reach necessary validity in the prognosis.

[Clinical validation of the caries preventive effect of mouth rinses with a mineralizing solution on the recently erupted permanent dentition].

This research was performed with the purpose of learning about effect of oral rinsing, every two weeks, with mineralizing solution (Minersol) on recently erupted permanent dentition. Reduction obtained in the incidence of caries at one year term ranged between 49.2 and 82.1% for first molar teeth and 23.4 and 36.3% for second molar teeth; both differences were significant, but no reduction was obtained in the incidence of caries in the bicuspid teeth. Preventing effect obtained is attributed to ionic incorporation in enamel superficial levels, which decreases the diffusion of acids acting in demineralization. It is concluded that the use of mineralizing solution in those ages of eruption of permanent dentition reduces incidence of caries and, therefore, its use as preventing method is recommended.

[Effect of a mineralizing solution (Minersol) on acid solubility resistance of enamel].

Degree of mineralization of enamel is one of the parameters mediating in its resistance to acid dissolution and at the stage of teething, the enamel is immature and, therefore, present a higher susceptibility to dental caries. This investigation was carried out with 38 preschool children (means = 5.5 years) and 19 children coursing second grade (means = 7.6 years). They were treated with 10 oral rinsing with mineralizing solution in order to evaluate its effect on enamel resistance to acid dissolution; colorimetric technique was used for such purpose. A study in vitro was also performed in impacted third molars extracted by surgery and to two halves of the clinical crowns of such molars the treatment was applied; the other two halves were taken as control. Increase of enamel resistance found was 18.6% in the study of preschool children and 34.6% in the children attending to second grade school. In both groups, 89.5% of the children increased enamel resistance and in the study in vitro increaser enamel was 14.9%.. It is concluded that the use of risings with mineralizing solution at the outbreak of permanent teething increase, significatively, enamel resistance, and that at the age of seven the enamel is still immature, thus its resistance to acid dissolution can be also increased using mineralizing solution.
