GINGIVAL HYPERPLASIA
GINGIVAL HYPERPLASIA
โข Findings: Hypertrophy of both the free and attached gingivae, particularly the interdental papillae (Fig. 33-9).
โข Inflammatory enlargement: Most common cause of gingival enlargement. Caused by edema and infective cellular infiltration caused by prolonged exposure to bacterial plaque; fibrosis occurs if untreated.
โข Drug-induced fibrous hyperplasia of gingivae: May cover the teeth and is associated with:
โข Anticonvulsants: Phenytoin, succinimides, and valproic acid.
โข Calcium channel blockers: Nifedipine and verapamil.
โข Cyclosporine.
โข Systemic conditions/disorders:
โข Pregnancy, puberty, vitamin C deficiency, and glycogen storage disease.
โข Chronic myelomonocytic leukemia (Fig. 33-9).
FIGURE 33-9 โข Gingival hyperplasia: Acute monocytic leukemiaโThe gingivae show hyperplasia resulting from infiltration with leukemic monocytes.
