What condition is caused by a reaction to anti-seizure medications that leads to an over-response of plaque?

Dilantin hyperplasia, which is also referred to as gingival overgrowth, is a condition that can occur as a side effect of certain anti-seizure medications, particularly phenytoin (Dilantin). This condition leads to an abnormal growth of gum tissue, which can result in an increased response to plaque accumulation. The excessive gum tissue can make it more difficult to maintain proper oral hygiene, further exacerbating the accumulation of plaque and leading to potential periodontal issues.

The mechanism behind this condition involves alterations in the cellular response of the gingival tissues, which can be triggered by the medication. Patients taking anti-seizure drugs may notice a significant increase in gingival tissue size, which showcases the connection between the medication and gingival health.

Understanding this condition emphasizes the importance of monitoring oral health in patients who are on such medications, as proactive measures can help mitigate the plaque-related issues that arise from gingival hyperplasia.
