Abstract:

External cervical resorption (ECR) is an uncommon form of root resorption. The etiology and pathogenesis of ECR remains obscure. The resorption is generally found serendipitously by radiological examination. Patients are commonly asymptomatic at the early stage; thus, they often miss the best chance to treat ECR. ECR is difficult to diagnose and treat. However, when left untreated, ECR leads to progressive, irreversible loss of hard dental tissue and even teeth extraction. Reports about ECR worldwide are few, most of which are case reports. This paper will systematically review the predisposing factors, pathogenesis, clinical manifestations, radiological presentation, histopathology, clinical diagnosis and subsequent treatment of ECR to provide a reference for clinicians.

Key words: root resorption, external resorption, cervical, external root resorption
