Gingival overgrowth induced by diltiazem. A case report.

Gingival overgrowth induced by diphenylhydantoin (Dilantin) has been well documented in the literature. Recently, there have been other medications with side effects causing Dilantin-like gingival overgrowth. This article presents a case in which diltiazem (Cardizem), a calcium-channel blocker, induced gingival overgrowth. A discussion of the clinical and histologic features and possible pathogenesis of the disorder is presented.
