Figure 12 A photomicrograph of a longitudinal section of the mandible of the treated group showing the osteoblasts (Ob) as flat basophilic cells constituting a single layer. Inside the trabeculae, osteocytes (O) are located within their lacuna. Osteoclast (Oc) is a multinucleated giant cell and occasionally seen situated in the Howship’s lacunae.
