Recurrent oral granuloma gravidarum during two pregnancies of a patient with orthodontic treatment: A case report

The aim of this article was to present the medical management and follow-up of a recurrent oral granuloma gravidarum (OGG). OGG is a common benign tumour that can occur during pregnancy in response to poor oral hygiene and hormonal factors. Its identification and management by primary health care professionals is necessary, including an orientation to a dentist, if needed. Indeed, this lesion may induce troubles such as gingival bleeding, oral hygiene difficulties, and sometimes pain or eating difficulties, but also presents a high risk of relapse. An early twenties woman consulted several times during two pregnancies for an OGG presented in the same proximal maxillary gingival area. The patient reported dental hygiene difficulties because of orthodontic treatment and developed this recurrent tumour four times in two years, despite surgical excisions. Oral hygiene, and information continuously provided by healthcare professionals are required to prevent gingival inflammation and recurrence of OGG. This tumour usually regresses spontaneously post-partum, except in the presence of aggravating factors such as orthodontics treatment and mouth breathing. Surgery of OGG is required when it interferes with normal oral functions.
