Abstract
The effect of a preventive program was studied in 12-14-yr-old children. 104 children (test group) participated in this program. After four visits in the first 6 wk, the children visited the oral hygienist five times a year to revieve professional oral prophylactic treatment and instructions. Additionally a fluoride application (Duraphat) was given two times a year. Children of a control group (n = 117) received no prophylactic treatment. Diet was not controlled in either test or control group. After 2 yr mena caries increment amounted to 2.7 .+-. 2.8 new DFS in the test group and 5.0 .+-. 4.2 new DFS in the control group, respectively. The new pronounced differences between the two groups could be found on the proximal surfaces. In all, caries was reduced by 46% during the 2-yr period. Plaque accumulation and frequency of gingivitis were significantly reduced only in the test group (67% and 55%, resp.). The data revealed that the program both caries and gingivitis to a remarkable extent.
