Effects of surface demineralization (8hr and 24hr) on RPI parameters, pre-drying and post-drying RPI measurements
| Total Indentation Distance (TID) - μm | Indentation Distance Increase (IDI) - μm | |
|---|---|---|
| Pre-demineralization (8hr) | 102.06 ± 8.01 | 13.03 ± 1.50 |
| Post-demineralization (8hr) | 142.31 ± 19.49* | 17.49 ± 3.59* |
| Pre-demineralization (24hr) | 86.63 ± 23.36 | 13.62 ± 3.83 |
| Post-demineralization (24hr) | 192.57 ± 40.79* | 21.88 ± 5.09* |
