AYLWIN RAMIREZ, J; SAAVEDRA MAUREIRA, A; HIDALGO RIVAS, A  e  PALMA DIAZ, E. Prognosis in orthodontic treatment of root resorption of teeth caused by impacted canines: A literature review. Av Odontoestomatol [online]. 2018, vol.34, n.1, pp.11-17. ISSN 2340-3152.


Ectopically positioned canines have a high prevalence of lateral incisors with root resorption (RR). The process of RR ceases when the injury is removed. The present literature review evaluated the prognosis of maxillary lateral incisors with RR produced by impacted canines.


The severity of RR contributes to plan the objectives of orthodontic treatment. Mild RRs with no pulp involvement, have been shown to have a good prognosis in the long term. Therefore, the decision of not extracting a tooth with mild RR would be adequate. In moderate RR with loss of vitality, endodontic treatment is indicated. A high rate of success has been reported in cases of RR of up to the middle radicular third. Teeth with severe RR have a doubtful prognosis. Reports of 23-years follow up cases show that preservation of teeth with severe RR is possible, without a deterioration in its condition, even when extensive orthodontic movements have been applied. The decision on extracting or preserving the affected teeth must be made after considering the degree of RR, the tooth space discrepancy, post-treatment stability of the affected teeth and the clinician`s expertise. Also, considering that canines in its physiological position give the required functionality for an organic occlusion and ideal esthetics.


It is possible to keep teeth with severe RR in the long term without changes in its vitality, color alterations or increased mobility. However, further studies are needed that justify the decision on extracting or preserving teeth with severe RR.
