  Purpose
Phenytoin, a common anti-seizure drug, leads to cosmetically unacceptable side effect of gingival overgrowth in a significant number of patients. There is some evidence of therapeutic effect of folic acid in cases of established phenytoin induced gingival overgrowth. In this study, the aim is to study the prospective preventive effect of low dose oral folic acid supplementation on phenytoin induced gingival overgrowth in epileptic children.

Condition Intervention Phase
Gingival Overgrowth Drug: folic acid Drug: placebo Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: Effect of Low Dose Oral Folic Acid Supplementation on Phenytoin Induced Gingival Overgrowth: A Randomized Double Blind Controlled Trial.
