−: Grade 0, no inflammation, vascular proliferation, or fibrosis.
+: Grade 1, mild inflammation (<50 inflammatory cells) (×40), mild vascular proliferation (<5 vessels) (×40), and mild fibrosis.
++: Grade 2, moderate to severe inflammation (>50 inflammatory cells) (×40), moderate to severe vascular proliferation (>5 vessels) (×40), and moderate to severe fibrosis.
PRF: platelet-rich fibrin.
