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.

Background factors of enamel focal demineralization in groups of Finnish and Russian children.

The aim of this study was to analyze the occurrence of EFD lesions in relation to some background factors in Finnish and Soviet children. Children aged 7, 9 and 12 years (n = 1187) were examined clinically in Helsinki, Kuopio (Finland), Moscow and Leningrad (USSR). A questionnaire sent to the parents was used to collect data on toothbrushing frequency, use of sweets, cakes, soft drinks, sugar-sweetened tea/coffee and mother's education. In addition to bivariate analysis, log-linear regression models were used for comparing the simultaneous association in two ethnic groups. In general, the Finnish children had more EFD lesions than the Soviet children did. Among the Finns no consistent associations were found between the number of EFD lesions and the use of different sugar products or differences in toothbrushing habits. The number of EFD lesions decreased consistently according to mother's education with the Finnish children, but not with the Soviet children. The final multivariate model for Finnish children included age, toothbrushing frequency, place of residence (Kuopio) and use of soft drinks. The respective model for the Soviet children included age and place of residence (Leningrad). Evidently, the demineralization process or tooth resistance differs in these two ethnic groups.

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.

Mineralizing agents in caries prevention: a review of the effects of Remodent.

Caries reduction from tooth brushing with Remodent occurs according to age, from 37.8% to 83.7% during a two to three year follow-up. The highest reduction was gained when the program was started at the age of 2. When Remodent-solution and -varnish were tested in one to three year follow-up, reductions in caries occurred from 20% to 91%. These studies also showed that the effect was best when the preventive treatment was started early.
