Hyperplasia of gingival epithelium
Calcification of dental pulp

The correct answer is: Disruption of gingival fibers and inflammatory infiltrate of plasma cells and lymphocytes

Chronic gingivitis is characterized by inflammation of the tissues surrounding the teeth. The correct answer, C, describes the specific histopathologic changes that occur in chronic gingivitis. Option A, hyperplasia of gingival epithelium, may be seen in other types of gingivitis but is not specific to chronic gingivitis. Option B, calcification of dental pulp, is not a characteristic feature of gingivitis. Option D, increased cementum formation, may occur in periodontitis but is not specific to chronic gingivitis.
