Soft Tissue Response to Titanium Abutments with Different Surface Treatment: Preliminary Histologic Report of a Randomized Controlled Trial

Figure 1

Soft tissue around healing abutment. Histological evaluation of soft tissue surrounding plasma-conditioned abutments (Plasma Group). (a) Histological view showing rete pegs, with little round cell infiltration and to the right keratinized epithelial cells (×100, acid fuchsine and toluidine blue staining). (b) Histological view showing absence of acute infiltrate, minimal chronic infiltration, and diffuse presence of collagenization bands (×200, acid fuchsine and toluidine blue staining).
