Evaluation of the effect of interexaminer reliability in clinical trials of dental caries prevention.

Data from a 3-yr clinical trial were used to assess reliability of two dentists who, without standardizing techniques, independently examined 286 continuous participants. Only 13.1 of 128 tooth surfaces (third molars excluded) showed a change in caries status during the trial by one or both examiners' findings. Although there was poor agreement between the examiners (46.5%) on these changes, they agreed very closely on measuring the cariostatic effects in the various treatment groups because the disagreements were random and were similar among groups.

Prevalence of dental caries and dental fluorosis in areas with optimal and above-optimal water fluoride concentrations.

The prevalence of dental caries and dental fluorosis was assessed among 807 schoolchildren in four areas of Illinois where the respective water supplies contained natural fluoride at concentrations of 1, 2, 3, and 4 times the recommended optimal for the geographic area. Mean caries scores in all three above-optimal fluoride areas were significantly lower than in the optimal area. The prevalence of dental fluorosis was characteristically low in the optimal fluoride area. Substantial increases in fluorosis occurred in the above-optimal fluoride areas, with the condition being most pronounced in the 4-times optimal area.

A program self-administered fluorides in a rural school system.

In 1972, a self-administered fluoride program was initiated in Nelson County, VA, a fluoride-deficient area. Children in elementary school (grades K-6) ingest daily a 1-mg fluoride tablet, rinse weekly with 0.2% NaF solution and receive fluoride dentifrice for home use. In 1978, dental examinations of elementary schoolchildren (ages 6-12) who had continuously participated in the program for 1 to 6 years showed a prevalence of 2.70 DMFS, 45% lower than the score of 4.89 DMFS for their cohorts at the baseline. The preventive program inhibited dental caries effectively in all types of surfaces, but the reduction in proximal surfaces of 85% is particularly striking. Findings of high school children (ages 13-17) in 1978, who had not participated in the elementary school program for 1-5 years, showed evidence of strong post-treatment effects. At each succeeding follow-up survey, benefits have continued to improve. For elementary school participants, benefits were 17.7% after 2 years, 35.3% after 4 years and 44.8% after 6 years. Weekly fluoride mouthrinsing and daily ingestion of a fluoride tablet are feasible school-based procedures for the prevention of dental caries. Combined with the use of a fluoride dentifrice at home, these procedures have a pronounced cariostatic effect.

Pit and fissure sealants in private practice and public health programmes: analysis of cost-effectiveness.

Most studies of fissure sealants have concentrated on their ability to prevent caries of occlusal surfaces. The cost-effectiveness of the procedure has been generally ignored and even in those reports where values for the cost of sealant applications are given they tend to be overstated. In the majority of studies all sound teeth in one half of the subject's mouth were sealed, the other side acting as a control. Since only a proportion of the teeth sealed would have become carious this could be held to be wasteful and in a private practice where the caries profile of the subject was known, a more economical regimen could have been adopted. When sealants are applied by a dentist the cost appears likely to exceed the potential cost of restorations saved, but this could be altered if it were possible for the procedure to be carried out by auxiliaries. It is concluded that fissure sealants have a worthwhile contribution to make when used as an integral part of a total preventive regime which includes the use of professionally and self-applied fluorides. With their intelligent use it should be possible to preserve many more dentitions free of caries into adult life.
