Table 1.
Cyclic fatigue resistance and torsional resistance (mean ± standard deviation).
| Cyclic fatigue resistance | Torsional resistance | ||
|---|---|---|---|
| NCF | UTS (Ncm) | ARF (°) | |
| K3 | 1683.0 ± 349.4a | 3.31 ± 0.55a | 526.4 ± 110.7a |
| K3XF | 1995.0 ± 295.5a | 3.14 ± 0.42a | 678.0 ± 96.5b |
| K3H | 17760.5 ± 5199.4b | 3.70 ± 0.73a | 605.1 ± 133.0a,b |
Different superscript letters in the same column indicate a statistically significant difference between groups (P < 0.05).
NCF: number of cycles to fracture; UTS: ultimate torsional strength; ARF: angle of rotation to fracture.
