- ObjectivesTo evaluate approximal caries increment among 12- to 16-year-olds in a low caries prevalence area in Sweden after a 3.5-year school-based fluoride (F) varnish programme with Bifluorid 12 and Duraphat. MethodsThe design was a RCT study with 1365 adolescents, divided into following four groups: Group 1 Bifluorid 12 two applications/year; Group 2 Duraphat two applications/year; Group 3 Bifluorid 12 four applications/year and Group 4 no F varnish at school. 1143 children (84%) completed the study. Approximal caries was registered on bitewing radiographs. ResultsThere were no statistically significant differences in caries prevalence among the groups either at baseline or after 3.5years . The caries increment for Group 1 was 1.342.99 (mean +/- SD), 1.24 +/- 2.84 for Group 2, 1.07 +/- 2.66 for Group 3 and 1.25 +/- 2.75 for Group 4, with no statically significant differences either between Bifluorid 12 and Duraphat with the same frequency of F varnish applications or between the F groups and the control group. ConclusionsIn an area with low caries prevalence in Sweden, the supplementary caries-preventive effect of school-based F varnish applications, to regular use of F toothpaste at home and to regular caries prevention given at the Public Dental Clinics, appears to be nonsignificant regarding approximal caries increment.
