Subjects. A cohort of 5927 children in grades 2, 3, 8, and 9 living in British Columbia, Canada, were examined in 1993-1994. Fifty-one percent of the children were reexamined in 1996-1997 when they were in grades 5, 6, 11, and 12. Exposure. In 1992, as a result of referenda, Comox/Courtenay/Campbell River stopped water fluoridation, while Kamloops did not. These 2 areas in Canada were compared with respect to caries scores. Main Outcome Measure. A modified D1D2MFS Index was used, in which D1 is an incipient lesion and D2 is a cavitated lesion. Main Results. In grades 5 and 6, the D1D2MFS Index in still-fluoridated and fluoridation-ended communities was 0.5 and 0.6, respectively. In grades 11 and 12, the D1D2MFS Index in still fluoridated and fluoridation-ended communities was 1.8 and 2.3, respectively. These differences were nonsignificant. Significant differences were present when components (fillings and D1 and D2 lesions) of the D1D2MFS Index were evaluated separately, with those in the fluoridated communities having more fillings.
