The resorption of the tooth root is a pathological process which can occur following tooth infection, orthodontic treatments or in the presence of unerupted teeth in the jaw. Although this condition is generally asymptomatic and missed in diagnosis, external root resorption may result in tooth mobility and if not diagnosed and treated at an early stage, might eventually result in tooth loss.
Our explicit search revealed that despite the relatively high prevalence of this defect, treatment options are generally case-dependant and there is no high level evidence in this respect. We also identified several empirical reports which require further consideration. It is concluded that future research should aim to provide evidence for practitioners and consumers to make informed decisions about the most appropriate means of managing external root resorption and it appears that the clinician's experience in conjunction with patient's preference would make up the most suitable therapeutic approach.
