title: Case report: management of an impacted maxillary canine in association with a deviated palatal premolar root.
abstract: OBJECTIVE
  The purpose of this case report is to present the management of an impacted maxillary canine adjacent to a deviated palatal first premolar root.
  
  
  BACKGROUND
  Maxillary canine impactions are of multifactorial etiology. The incidence of maxillary canine impaction ranges from 1% to 3%. One of the reasons for canine impaction might be a deviated palatal premolar root. To date, a total of six cases have been described where impacted maxillary canines were found in close proximity to a deviated palatal first premolar root.
  
  
  METHODS
  A male patient, aged 17 years 3 months, with a Class I molar relationship was referred for the continuation of orthodontic therapy. Leveling was completed in the lower and upper arches. Although sufficient space was available in the upper arch the left canine had not erupted. Radiographic examination disclosed a deviated palatal root of the first premolar in the canine eruption path.
  
  
  CONCLUSIONS
  A multidisciplinary treatment approach for the maxillary impacted canine adjacent to a deviated palatal premolar root is described. The premolar was endodontically treated and the deviated root surgically resected. The impacted canine was then orthodontically erupted into position.
  
  
  CONCLUSIONS
  A deviated maxillary premolar root may cause canine impaction. A multidisciplinary approach facilitates successful treatment results in such cases.
