Initial sign of pheytoin induced gingival enlargement
1) Bleeding from gingiva on probing
2) Pale and fibrotic gingiva
3) Interdental enlargement of papilla
4) Increased sulcus depth on probing
π Explanation:
The initial clinical sign of phenytoin-induced gingival enlargement is typically the enlargement of the interdental papillae, which then progresses to involve the marginal gingiva. The tissue usually appears pale and fibrotic, rather than inflamed or bleeding.
