Three hermetics are assessed: chemically hardened Delton, light-hardened Estiseal, and composite Evikrol. The study was carried out in 126 children aged 6 years. The decrease of the increment of dental caries depends on the retention of hermetics on the occlusion surface of the teeth, and the efficacy of caries prevention in permanent teeth is much higher if hermetic sealing of fissures and fossae is combined with local fluorine prophylaxis and oral hygiene. All types of hermetics can be used to prevent permanent teeth caries, but chemically hardened ones should be preferred.

Questionnaires were distributed among 1187 children aged 7, 9 and 12 living in Moscow, St. Petersburg, Helsinki and Kuopio and dental examinations of these children were carried out. Children together with their parents answered the questions concerning tooth cleaning, consumption of sweets, parents' education. Analysis of the results helped detect the population motivation to proper care of the oral cavity and time course of this motivation.

Surface-specific effect of a mineralizing agent on the permanent teeth and on periodontal status.

In a two-year clinical trial the surface-specific effect of a mineralizing agent on selected permanent teeth was evaluated as well as the effect of this agent on periodontal health in children. Compared with positive controls (Control group, n = 123, biweekly mouthrinsing with placebo and 0.2% NaF solutions), among children in the test group (n = 123, biweekly mouthrinsing with 2% Remodent and 0.2% NaF solutions) the mineralizing agent clearly affected periodontal health (as determined by the prevalence of subjects with gingival bleeding and occurrence of affected sextants at risk) positively, in addition to having a positive effect on the incidence of EFD lesions. The mineralizing agent tested was not found to have adverse effects (as determined by the prevalence of subjects with dental calculus and occurrence of affected sextants at risk). Use of the mineralizing agent is recommended especially during posteruptive maturation of permanent teeth.

Effect of the mineralizing agent on the permanent teeth.

In a two-year pragmatic clinical trial, the effect of the mineralizing agent was evaluated on permanent teeth of the first eruption group among Finnish children (7-years old at the beginning of the study) with a low prevalence of DFS. In the test group (n = 123, biweekly mouthrinsing with a 2% solution of mineralizing agent and 0.2% NaF solution) the percentage reduction in increment of both EFDS and DFS was high, whereas in the control group (n = 123, biweekly mouthrinsing with placebo and 0.2% NaF solutions) the incidence for symptoms of caries disease did not differ from that normally found in this age cohort. Positive clinical effect of tested solution was age-related and was associated with remineralization of old and inhibition of occurrence of new EFD lesions.
