XPS samples prepared from 10 premolars | The 119 sites tested were distributed as follows: |
Group 1a (middle tooth sections) controls with no pH cycling (16 sites)* |
Group 1b (middle tooth sections) controls with no composite, pH cycled (16 sites)* |
Group 2 Transbond XT (resin control, pH cycled) (29 sites)** |
Group 3 Quick Cure (resin with fluoride, pH cycled) (29 sites)** |
Group 4 Aegis Ortho (resin with ACP, pH cycled) (29 sites)** |
*4 lateral teeth segments × 2 sites for each tooth (top and |
bottom) × 2 time points [day 1 (T1) and then at day 28 (T2)] = 16 Sites. |
**4 lateral teeth segments × 2 sites at T1 (top and bottom) and |
4 lateral teeth segments × 3 sites at T2 (top, middle under the |
resin, and bottom) + 3 lateral teeth segments × 3 sites repeated |
for interobserver reliability = 29 sites |
|
PLM samples prepared from 30 premolars | For each of the four groups (control, Transbond XT, Quick Cure, |
and Aegis Ortho), there were 8 lateral tooth segments with |
multiple slices prepared for PLM at day 42. |
