Effect of a preventive program based on professional toothcleaning and XXXX application on caries and @entity2522 .

@entity1 @entity2522 @entity1388
The effect of a preventive program was studied in 12-14-yr-old @entity1 . 104 @entity1 (test group) participated in this program. After four visits in the first 6 wk, the @entity1 visited the oral hygienist five times a year to receive professional oral prophylactic treatment and instructions. Additionally a @entity1388 application (Duraphat) was given two times a year. @entity1 of a control group (n = 117) received no prophylactic treatment. Diet was not controlled in either test or control group. After 2 yr mean 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 most 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 @entity2522 were significantly reduced only in the test group (67% and 55%, resp.). The data revealed that the program reduced both caries and @entity2522 to a remarkable extent.
