Figure 3

Soft tissue around healing abutment. Histological evaluation of soft tissue surrounding no conditioned abutments (Control Group). (a) High magnification view showing keratinized oral gingival epithelium with rare presence of neutrophils and diffuse presence of lymphocytes and of collagenization bands (×200, acid fuchsine and toluidine blue staining). (b) Low magnification histological view showing keratinized oral gingival epithelium with absence of acute infiltrate, minimal chronic infiltrate, and diffuse collagenization bands (×100, acid fuchsine and toluidine blue staining).
