Maxillary premolar resorption by canines: three case reports.
Three unusual cases of maxillary premolar root resorption are reported. Three teenage patients were referred to the orthodontic department for management of ectopic maxillary canines. Radiographic examination revealed unilateral premolar root resorption in all three patients. This represents an unusual finding. Whereas the prevalence of maxillary lateral incisor root resorption secondary to palatally ectopic canines has been reported, the prevalence of premolar root resorption is unknown. This report discusses the findings in the context of the available literature. The postulated aetiology and the need for early diagnosis are highlighted.
