Histologic images of inflammatory cell infiltration and tissue reaction characteristics at the end of implanted tubes in MTA and Diaket groups (hematoxylin-eosin staining). (a) Few macrophages and giant cells (G) observed in the MTA group at 30 days; original magnification × 400. (b) Osteoid-like material (OS) observed in the area adjacent to MTA (M) at 60 days; original magnification × 100. (c) Severe and extensive liquefactive necrosis or suppuration (N) in the area adjacent to Diaket material (M) at 7 days; original magnification × 100. (d) Giant cells (G) and macrophages in the connective tissue adjacent to Diaket at 30 days; original magnification × 200. (e) Mild inflammation observed in the area adjacent to Diaket (M) at 60 days; original magnification × 100. (f) Predominance of lymphocytes in the Diaket group at 60 days; original magnification × 50.
