[Generalised external apical root resorption: aetiology in 3 radio-graphically comparable cases].

There are various types of dental root resorption. Local external apical root resorption is often recognised after orthodontic therapy. However, a generalised form is rare. 3 patients with the rare dental condition 'idiopathic generalised apical external root resorption' were referred and treated within an 8-year period. The prognosis of preserving the dentition is for the most part unfavourable and only a very speculative prediction about (the pace of) progression can be given. No standard treatment protocol is available for this condition. A dental treatment plan should be flexible and individually adjusted to patient's wishes.
