Gingival overgrowth occurs mainly as a result of certain anti-seizure, immunosuppressive, or antihypertensive drug therapies. Excess gingival tissues impede oral function and are disfiguring. Effective oral hygiene is compromised in the presence of gingival overgrowth, and it is now recognized that this may have negative implications for the systemic health of affected patients. Recent studies ...

Context: Gingival overgrowth can be associated with pharmacotherapy. Among the offending medications of gingival overgrowth, phenytoin is the first reported and the most common agent. Evidence Acquisition: A literature search was performed with the relevant key words in different databases such as Scopus, Medline, Embase, and Google scholar. Results: About 50% of individuals receiving phenytoin...

INTRODUCTION Gingival overgrowth has been linked to multiple factors such as adverse drug effects, inflammation, neoplastic processes, and hereditary gingival fibromatosis. Drug-induced gingival overgrowth is a well-established adverse event. In early stages, this gingival enlargement is usually located in the area of the interdental papilla. Histologically, there is an increase in the differen...

57 INTRODUCTION Drug-induced gingival overgrowth is a disfiguring side effect of anticovulsants, calcineurin inhibitors, and calcium channel blocking agents. Phenytoin is an antiepileptic drug that acts on sodium channels in mammal cells. Clinically detectable gingival overgrowth occurs as the principal side-effect of phenytoin therapy in approximately half of the treated patients. Although the...

Some kinds of drugs such as calcium (Ca(2+)) channel antagonists, antiepileptics and immunosuppressants cause gingival overgrowth as a side effect, the mechanism of which is still unclear. We have examined the effects of isradipine, one of the dihydropyridine-derivative Ca(2+) channel antagonists, on cultured human gingival fibroblast Gin-1 cells. In the present study, to elucidate the mechanis...
