Table 6 Forces in Newton (N) measured at fracture for all tested groups (mean ± standard deviation). Significant values are in bold. The same upper case letters indicate no statistically significant differences in rows (p > 0.05) whilst the same lower case letters indicate no statistically significant differences in columns for factor “material” (p  > 0.05). The same symbols indicate no statistically significant differences in both rows and columns within TEC or TEC for factor “aging”(p > 0.05).
