Summary

Unusual root resorption in premolar teeth was observed in three teenage orthodontic patients with ectopic maxillary canines. Early diagnosis is crucial for managing this rare condition and preventing further dental complications.

Area of Science:

  • Dentistry
  • Orthodontics
  • Oral Surgery

Background:

  • Ectopic maxillary canines are a common orthodontic concern.
  • Root resorption, particularly of adjacent teeth, can occur secondary to canine impaction.
  • Maxillary lateral incisor root resorption is a known complication of palatally displaced canines.

Observation:

  • Three teenage patients presented with ectopic maxillary canines requiring orthodontic intervention.
  • Radiographic examination revealed unexpected unilateral root resorption of premolar teeth in all three cases.
  • This finding is unusual as premolar root resorption is not commonly reported in association with ectopic canines.

Findings:

  • The study reports a rare occurrence of maxillary premolar root resorption in patients with palatally ectopic canines.

  • The prevalence of premolar root resorption in such cases is currently unknown.
  • Available literature on root resorption secondary to canine impaction primarily focuses on incisors, not premolars.

    • Implications:

    • Highlights the need for heightened awareness and vigilance regarding premolar root resorption in orthodontic cases.
    • Suggests that early and thorough radiographic assessment is essential for timely diagnosis.
    • Emphasizes the importance of further research to understand the aetiology and prevalence of this unusual complication.
