* Data in parenthesis represent ranges; ** Mann-Whitney test; ^† Degradation rate was calculated as follows [11]: degradation rate (mm/year) = $\frac{\mathrm{initial}\mathrm{volume}-\mathrm{RV}}{\mathrm{initial}\mathrm{surface}\mathrm{area}\mathrm{x}\mathrm{time}}$; where initial volume is 44.87 mm3 and the initial surface area is 141.83 mm².
