BACKGROUND: Ageing produces several changes on the oral cavity, and oral varix (OV) is among the most common, and they are related with some medical diseases; however, this association is not clear. OBJECTIVE: The aim of this article is to offer a review of OV, regarding aetiology, clinical and histological features, associated factors, treatment and its clinical significance. CONCLUSION: Except for a higher incidence of OV in elder individuals, there is limited evidence that supports its relationship with medical conditions such us cardiovascular diseases or portal hypertension. Also, there is no consensus regarding its pathogenesis, but the hemodynamic theory embodies the most comprehensive approach. The high prevalence in elderly people stresses the need for regular oral examination, but more detailed studies regarding OV in relation to systemic diseases are needed.
