Mean values and standard deviations of mechanical properties of dental hard tissues from compression tests (n = 10/material).
| Compression test results | |||
|---|---|---|---|
| Specimen | Maximum stress (MPa) | Maximum strain (%) | E (MPa) |
| Enamel | 62.2 ± 23.8 | 4.5 ± 0.8 | 1338.2 ± 307.9† |
| Dentin | 193.7 ± 30.6 | 11.9 ± 0.1 | 1653.7 ± 277.9† |
| ED | 126.1 ± 54.6 | 8.7 ± 2.7 | 1628.6 ± 482.7† |
E: elastic modulus; ED: enamel–dentin.
Not significantly different (p > 0.1) in t-test.
