Exposed root surface: a review of aetiology, management and evidence-based outcomes of treatment

Gingival recession and the associated exposure of root surfaces are a common finding in our patient population. Many factors have been proposed as influencing the development of marginal tissue recession and controversy exists over the concept of an "adequate" zone of attached tissue. We will explore the aetiology of marginal recession and the factors affecting the outcome of treatment of these defects through an evidence-based perspective. A review of currently accepted surgical techniques backed by evidence of success will be presented to familiarize the reader with procedures used to treat exposed root surfaces.
