Conservative management of amlodipine influenced gingival enlargement

Nonsurgical Management of Drug-induced Gingival Overgrowth in a Young Patient

Background

Gingival enlargement or gingival overgrowth (GO) is a very common complication of the various classes of drugs and the most common being, the anticonvulsant drug phenytoin (PHT). PHT and its metabolites have a direct effect on the periodontal tissues; with poor oral hygiene also contributing to the severity of inflammation in patients with drug-induced gingival overgrowth (DIGO).

Case description

Here we present a case of PHT-induced gingival overgrowth (PGO) in a 12-year-old male patient and discuss the management of the condition.

Conclusion

Management of drug-induced overgrowth of gingiva includes strict oral hygiene maintenance practice, meticulous professional care with several adjunctive periodontal therapies like photodynamic therapy and Local drug delivery. Surgical treatment is indicated if the overgrown tissue has become fibrotic.

Clinical significance

The pediatric dentist plays an important role in early identification and proper management of the condition by timely intervention and collaboration with other specialists.

Drug-induced gingival overgrowth: A critical insight into case reports from over two decades

Drug-induced gingival overgrowth (DIGO) is a well-recognized adverse effect of certain systemic medications. Calcium channel blockers, anticonvulsants, and immunosuppressants are frequently implicated drugs in the etiology of DIGO. Drug variables, plaque-induced inflammation, and genetic factors are the three important factors in the expression of gingival changes after systemic medication use. Careful clinical examination and thorough history taking form the basis for diagnosis of DIGO. Histopathological examination is often neglected; however, it is an important aid that helps in differential diagnosis. Cessation or change of drug and meticulous plaque control often leads to regression of the lesion, which however might need surgical correction for optimal maintenance of gingival health. The purpose of the present article is to review case reports and case series published in the last two decades and to assimilate and compile the information for clinical applications such as diagnosis and therapeutic management of DIGO.

Nonsurgical management of nifedipine induced gingival overgrowth

Drug-induced gingival overgrowth is frequently associated with three particular drugs: phenytoin, cyclosporin, and nifedipine. As gingival enlargement develops, it affects the normal oral hygiene practice and may interfere with masticatory functions. The awareness in the medical community about this possible side effect of nifedipine is less when compared to the effects of phenytoin and cyclosporin. The frequency of gingival enlargement associated with chronic nifedipine therapy remains controversial. Within the group of patients that develop this unwanted effect, there appears to be variability in the extent and severity of the gingival changes. Although gingival inflammation is considered a primary requisite in their development, few cases with minimal or no plaque induced gingival inflammation have also been reported. A case report of gingival overgrowth induced by nifedipine in a patient with good oral hygiene and its nonsurgical management with drug substitution is discussed in this case report.

Drug-induced gingival overgrowth: The nemesis of gingiva unravelled

Drug-induced gingival overgrowth or enlargement manifests as abnormal growth of the gingiva due to an adverse drug reaction (ADR) in patients treated with anticonvulsants, immunosuppressants, and calcium channel blockers. As gingival enlargement develops, it affects the normal oral hygiene practice and may interfere with masticatory functions. It gradually becomes a source of pain and the condition often leads to disfiguration. Within the group of patients that develop this unwanted effect, there appears to be variability in the extent and severity of the gingival changes. It would seem pertinent to identify and explore possible risk factors and relating them with the treatment plan. This article throws light on respective drugs and their association with gingival overgrowth and approaches to treatment based on current knowledge and investigative observations.
