Figure 2. Representative photomicrograph of morphology of epithelial tissues and bone crest height of the groups studied. Note height of the alveolar crest (blue line) and normal appearance of the division of the oral, sulcular and junctional epithelium (hematoxylin and eosin, × 40). AC: alveolar crest; JE: junctional epithelium; OE: oral epithelium; OSE: oral sulcular epithelium.

Figure 3. Representative photomicrographs of evidence of bone resorption in all groups studied. Note osteoclast in Howship’s lacunae, indicating an area of bone resorption (hematoxylin and eosin, × 1,000). HL: Howship’s lacunae; OC: osteoclast.

Figure 4. Representative photomicrographs of evidence of bone formation in all groups studied. Note areas of bone formation with presence of incremental lines, Haversian canal and osteoblasts (hematoxylin and eosin, × 400). HC: Haversian canal; IL: incremental lines; OB: osteoblasts.
