Figure 3.

Wear depth mean values (micron) of experimental composite resins after 15,000 cycles of the 2-body wear test. The same lower letters indicate that there is no significant difference in wear depth between experimental composite resins with different weight fractions of HE-Phene in the resin matrix. The same upper letters indicate that there is no significant difference in wear depth between experimental composite resins with different weight fractions of TE-Phene in the resin matrix. The asterisk * indicates the statistical differences between composites with different Phene like monomers at the same mass fraction in resin matrix.
