A Comparison of the Process of Remodeling of Hydroxyapatite/Poly-D/L-Lactide and Beta-Tricalcium Phosphate in a Loading Site

Figure 8

Tissue sections were stained for COL 1 and observed at ×200 magnification. ((a), (c), and (e)) TCP group. ((b), (d), and (f)) HP group. ((a), (b)) 1 month. ((c), (d)) 3 months. ((e), (f)) 12 months. Most of the infiltrated fibrous tissue in the bioresorbable scaffolds was positive for COL1. The HP groups showed COL1-positive tissue infiltration; particularly, the 1- and 3-month HP groups showed marked COL1-positive tissue infiltration. On the other hand, the TCP groups did not show much fibrous tissue infiltration. Scale bars: 200 µm.
