Table 3.
The mean biaxial flexural strength (BFS) values expressed in MPa and standard error (SE) of the glass ionomers tested, by test group.
| Glass ionomer | Group 1 (SC) | Group 2 (HC30) | Group 3 (HC60) | |||
|---|---|---|---|---|---|---|
| Mean | SE | Mean | SE | Mean | SE | |
| Chemfil Rock | 61.4d | 1.1 | 73.1e | 1.2 | 75.5e | 1.3 |
| EQUIA system | 67.9d | 1.1 | 73.1e | 1.3 | 78.1f | 1.1 |
| Fuji 9 Gold Label | 43.4a | 0.6 | 52.1b | 1.2 | 54.5b | 1.1 |
| Ketac Molar Easymix | 39.6a | 0.6 | 51.7b | 1.1 | 55.2c | 1.1 |
SC: autocure; HC30: light cured for 30 seconds; and HC60: light cured for 60 seconds.
The number of samples is 30 per glass-ionomer group. Different superscript letters show significant statistical differences (the Bonferroni test) within the materials.
