Effect of fiber orientation and placement on fracture resistance of large class II mesio-occluso-distal cavities in maxillary premolars: An <i>in vitro</i> study.

This table also shows that the mean difference in fracture resistance between Group 1 and the rest of all other groups are highly statistically significant at 1% level of significance, and this situation is also similar for Group 2 as well, that is the mean difference in fracture resistance between Group 2 and rest of all the groups are also highly significant at 1% level of significance.
