Table 1.
Baseline caries frequency (mean, SD) and percentage distribution of Cariogram risk categories in all patients, the drop outs and those that remained after 3 years (follow-up)
| Variable | All patients | Drop outs | Follow-up |
|---|---|---|---|
| n = 1,295 | n = 313 | n = 982 | |
| DFT | 3.4 (3.3) | 4.4a (3.7) | 3.1 (3.1) |
| DFS | 4.9 (5.6) | 6.8a (6.9) | 4.3 (5.0) |
| Cariogram risk category (%) | |||
| 81-100 (very low risk) | 23.3 | 17.0 | 25.6 |
| 61-80 | 32.7 | 27.7 | 34.1 |
| 41-60 | 26.5 | 30.9 | 25.3 |
| 20-40 | 9.0 | 13.2 | 7.5 |
| 0-20 (very high risk) | 8.4 | 11.2 | 7.5 |
aSignificantly different from follow-up group (p < 0.05).
