The ability of Cur_WPI25_HAp (a) and Cur_WPI35_HAp (b) biomaterials to degrade in PBS (control), collagenase I (Coll I), and proteinase K (Prot K) solutions during 3, 6, and 9 weeks of incubation. The normal distribution of data was analyzed using a D’Agostino and Pearson omnibus normality test, then one-way ANOVA test followed by Tukey’s multiple comparison were performed in order to determine statistical differences between samples, p < 0.05: * Significantly different results compared to results obtained in PBS solution; # significantly different results compared to results obtained in collagenase I solution; $ significantly different results between data obtained after 3 weeks; @ significantly different results between data obtained after 6 weeks.
