PERIAPICAL GRANULOMA (CHRONIC APICAL PERIODONTITIS)
a mass of chronically inflamed granulation tissue at the apex of a nonvital tooth. No true granulomatous inflammation microscopically. a defensive reaction secondary to the presence of bacteria in the root canal These lesions are not static …………. periapical cysts or abscess formation. approximately 75% of apical inflammatory lesions
A radiolucency of variable size loss of the apical lamina dura. circumscribed or ill-defined.
Root resorption is not uncommon chronic low-grade inflammatory reaction will result in root resorption
Incomplete root canal therapy
Trauma devitalized two of these teeth Vitality test ………. . to eliminate the possibility of osseous dysplasia.
Histopathologic Features inflamed granulation tissue surrounded by a fibrous connective tissue wall. granulation tissue a variably dense lymphocytic infiltrate that is intermixed frequently with neutrophils, plasma cells, histiocytes, and, less frequently, mast cells and eosinophils. number of young capillaries surrounded by a mixed inflammatory reaction
Granulation tissue with intense chronic inflammation
Foam cells
Granulation tissue is not a component in all cases of chronic apical periodontitis. In older lesions you may see more fibrosis.
Russell bodies numerous plasma cells are present, scattered eosinophilic globules of gamma globulin
Collections of cholesterol clefts with associated multinucleated giant cells Cholesterin deposits indicate cellular degeneration.
