*2.5. Statistical Analysis*

Experiments were carried out both in decuplicate (*n* = 10, for extractions performed at four weeks), and triplicate (*n* = 3, for extractions performed at nine weeks), to achieve statistical significance. The unpaired Student's *t*-test was used to determine the level of significance, and *p*-values ≤ 0.05, ≤0.0001 and ≤0.00001 were considered to be significant and highly significant, respectively.
