Abstract

This report discusses a case of rare idiopathic root resorption in a 13-year-old female and highlights how an upper standard occlusal radiograph proved to be pivotal in the diagnosis and demonstration of its incidence. Management of the case is described, with discussion of treatment alternatives.

Clinical Relevance: Generalized idiopathic external root resorption is progressive. Before commencing orthodontic treatment, adequate clinical and radiographic examination is essential to facilitate appropriate management. Currently, UK orthodontists do not routinely take an upper standard occlusal radiograph pre-treatment. However, this case highlights the benefit of such diagnostic imaging, in specific circumstances.

Article

Root resorption is the term used to describe the process of progressive loss of dentine and cementum.1 Root resorption can be broadly classified based on the site of the process as internal or external. The main causes of root resorption are summarized in Table 1.

There are four further categories of root resorption:

Often the aetiology of root resorption may be multi-factorial.2 By definition, idiopathic root resorption arises where there is no identifiable cause and therefore absence of local or systemic factors.3,4 Idiopathic root resorption can be either localized or generalized. Two types of idiopathic root resorption have been observed; apical and cervical.5,6 Cervical idiopathic root resorption starts in the cervical area, progressing towards the pulp. In the apical idiopathic root resorption type, progression is coronal, resulting in slow shortening and blunting of the remaining root. Apical idiopathic root resorption is more common than the cervical type.7
