Summary
Tooth transposition, the interchange of adjacent teeth, is rare, affecting 0.4% of cases. Maxillary canine transposition to the central incisor site is exceptionally uncommon, often linked to early incisor loss.
Area of Science:
- Dentistry
- Orthodontics
- Oral Surgery
Background:
- Tooth transposition involves the positional interchange of adjacent teeth within the same quadrant.
- The incidence is approximately 0.4%, with the maxillary permanent canine being the most frequently involved tooth.
- Etiologic factors include genetics, trauma, and early loss of incisors.
Observation:
- Transposition of the maxillary canine to the central incisor site is a rare occurrence.
- This specific type of transposition is hypothesized to result from canine migration into the space created by an early-lost central incisor.
- Only two long-term radiographic studies have documented maxillary canine migration to support this hypothesis.
Findings:
- This report presents two cases of maxillary canine to central incisor transposition.
- One case includes long-term radiographic records, offering valuable documentation.
- The findings contribute to understanding the etiology of this rare dental anomaly.
Implications:
- The study highlights the rarity of maxillary canine transposition to the central incisor site.
- It provides clinical cases and long-term data to support the opportunistic migration hypothesis.
- Further research can refine understanding and management strategies for this condition.
