Abstract EN

Back-ground : Gingival overgrowths (GO) are induced by many factors.

They are sometimes associated with clinical attachment loss and with bone resorption.

Objective: This study is a clinical comparison between GO of various etiologies, for the purpose of determining the causes, etiologies and ratio of clinical attachment loss and bone resorption.

patients: 200 patients aged 12-57 years were enrolled in this study.

Gingival overgrowths were observed in the Periodontology Department, Damascus University, between 1996-1998.

Methods; Gingival overgrowths were scored at clinical examination.

Panoramic radiography, and histopathological study, were done.

A primary treatment to reduce the inflammation was applied, followed by surgery.

Results: Clinical attachment loss and bone resorption were observed in 17 (8.5%): -Nine patients with drug-induced GO; cyclosporine-A, phenytoin, medazepam, nifedipine, and diltiazem.

-Four patients with GO of unknown cause (in one of them we observed signs of HPV (human papilloma virus).

-Four patients with hormonal GO.

at puberty or pregnancy.

Conclusion : Gingival overgrowths are induced by multiple factors: drugs, hormones, and inflammations.

Sometimes they are of unknown causes.

Clinical detachment and bone resorption are found in 8.5% of GO our series.

Chronicity, presence of specific microflora, and abnormal immunological reaction might play a role in the emergence of GO associated with bone loss.
