Mean strength and gross stiffness values
| Group | Initial Failure Load (N)* | Treated Failure Load (N)* | Strength Restoration (%) | Initial Stiffness (N/mm)† | Treated Stiffness (N/mm)† | Stiffness Restoration (%) |
|---|---|---|---|---|---|---|
| 0 + 0 (n = 6) | 3349 | 1970‡ | 62 | 396 | 202‡ | 56 |
| 3 + 0 (n = 6) | 3044 | 1737 | 60 | 404 | 181 | 49 |
| 3 + 3 (n = 7) | 2488 | 1751 | 75 | 314 | 191 | 69 |
| 6 + 3 (n = 6) | 2692 | 1668 | 62 | 374 | 179 | 51 |
* Standard error of the mean (SEM) = 234 N.
† SEM = 39 N/mm.
‡ Specimens in the control group, though not treated, underwent the same reloading protocols as those in the treated groups.
