Failure mode counts of all the specimens after microtensile test.
| Resin cement | Polishing method | 24-hour water storage | 2-year water storage | ||||
|---|---|---|---|---|---|---|---|
| (a) | (b) | (c) | (a) | (b) | (c) | ||
| Etch-and-rinse | A | 17 | 0 | 3 | 15 | 3 | 2 |
| B | 19 | 0 | 1 | 16 | 2 | 2 | |
| Self-etch | A | 18 | 1 | 1 | 18 | 1 | 1 |

| Self-adhesive | A | 20 | 0 | 0 | 19 | 0 | 1 |
| B | 18 | 0 | 2 | 18 | 0 | 2 | |
Failure modes: (a) adhesive failure (failure within dentin/resin cements interface); (b) cohesive failure (failure solely within resin cements); (c) mixed failure (partially cohesive failure within resin cements with some adhesive failure).
