- purpose of this study was to elaborate a model for estimating the caries-reducing effect of a preventive measure with due consideration of background factors. The material comprised 50 children, who had consumed NaF tablets regularly during preschool age, and 76 comparable children who had never consumed NaF tablets. They were all examined at 12 and 13 yr of age. Information on caries and, as confounding factors, dietary habits, oral hygiene and microbiologic variables, was obtained on both occasions. Correlations between the parameters and caries, their discriminating effects and interaction between them were studied. The results showed that correction for confounding diminished the crude caries-reducing effect of NaF tablets. Streptococcus mutans and lactobacilli turned out to be the strongest confounders to discriminate well as single variables and to behave logically in analyses of interaction. Therefore, these factors are recommended in the first place for inclusion in a correction model. If the material is sufficiently large for a further breakdown, oral hygiene (represented by bleeding on probing) could be added. The model will be used in future studies of the preeruptive effect of NaF tablets on caries in permanent teeth in the same population.

- Dental fears and other fears were assessed in 67 patients with dental fear with the Corah Dental Anxiety Scale (CDAS), the Geer Fear Scale (GFS), and a behavioral dentist's rating scale (DR). Patients were selected because of extreme initial dental fear (n = 20), favorable response to treatment for dental fear (n = 23). CDAS change paralleled behavioral change (DR), supporting the usefulness of CDAS in assessing dental fear. GFS scores did not change in either group but were higher among patients who did not respond to treatment for dental fear; these findings are discussed in terms of treatment outcome prediction and treatment specificity.

- EMG, HR and SCR were continuously recorded during two Standardized Dental Examinations (SDE) of 15 dental phobics. Following the first SDE, the patients were assigned to two treatment groups, one receiving systematic desensitization followed by two separate amalgam restorations and one premedicated with Valium for the two restorations. The dentist rated the patients' behavior on a 5-point scale. Corah's Dental Anxiety Scale (DAS) was used prior to the first SDE and following the second SDE. The second SDE was conducted on a separate occasion following the second restoration. No significant correlations were found between any of the physiological measures and either the dentist's ratings or the second DAS or DAS change scores. Significant differences found between the two treatment groups on the dentist's ratings, second DAS, and change scores were not reflected by the physiological measures.

- The purpose of this study was to evaluate the preeruptive effect of NaF tablets on caries in proximal surfaces of permanent molars and premolars. The material consisted of 47 subjects who had consumed fluoride tablets for a minimum of 5 yr between 1/2 and 6 yr of age in accordance with recommendations from the National Swedish Board of Health and Welfare (F+-group) and 69 comparable children who had never consumed such tablets (F(-)-group). All had resided since birth in an area with a water fluoride concentration of 0.2 ppm and had been exposed to fluorides in toothpaste, mouthrinse solution and varnish since at least the age of 6. The children were examined by means of bitewing radiographs at the ages of 12, 13, 14 and 17. Two confounding factors, i.e. salivary counts of Streptococcus mutans and lactobacilli, were estimated and used for correction of crude caries differences. The mean values of these factors were higher in the F(-)-group than in the F+-group. The results showed a statistically significantly higher caries prevalence in the F(-)-group compared to the F+-group when the children were 14-yr-old, 4.4 vs. 2.9 DFS, corresponding to a caries reduction of about 34%. After correction for confounding, this was reduced to 24%, representing a non-significant difference of 1.1 DFS but still indicating a preeruptive effect. At the age of 17, the difference in caries prevalence was statistically not significant, 7.1 vs. 5.6 DFS, corresponding to a reduction of 21%. Based on corrected data, this was reduced to 15%.(ABSTRACT TRUNCATED AT 250 WORDS)
