Table 1. Means of Streptococcus mutans [log(cfu)/mL] in saliva according to the orthodontic bonding material and sample collection time.
| Fuji-Ortho (n=15) | Transbond XT (n=14) | ||
|---|---|---|---|
| Collection time | Mean (S.D.) | Mean (S.D.) | p value |
| T0 | 4.35 (1.03) | 4.69 (1.23) | 0.42 |
| T7d | 4.77 (0.85) | 5.28 (0.66) | 0.08 |
| T21d | 4.98 (1.13) | 5.19 (1.19) | 0.62 |
| T35d | 5.18 (1.09) | 5.20 (1.42) | 0.97 |
| T49d | 4.77 (1.47) | 4.79 (1.73) | 0.97 |
T0 = before bracket bonding. T7d, T21d, T35d, T49d = 7, 21, 35, and 49 days after bracket bonding, respectively. The p values express the results of the Student’s t-test for comparison of the materials at each collection time.
