Summary
Ectopic canine eruption can cause severe root resorption in adjacent teeth, particularly lateral incisors. Early radiographic detection is crucial as this condition is asymptomatic.
Area of Science:
- Dentistry
- Orthodontics
- Radiology
Background:
- Ectopic canine eruption is a common dental anomaly.
- Root resorption of adjacent teeth is a potential complication.
- Computed tomography (CT) offers detailed imaging for assessment.
Purpose of the Study:
- To determine the incidence of severe root resorption in permanent teeth adjacent to ectopic maxillary canines.
- To identify factors associated with this root resorption.
Main Methods:
- Retrospective analysis of CT images from 255 patients.
- Evaluation of 334 ectopic maxillary canines and adjacent teeth.
- Statistical analysis using chi-square and Fisher's exact tests.
Main Results:
- Severe root resorption occurred in 17.7% of cases, affecting lateral incisors most frequently (12.6%).
- Bucco-lingual position of the ectopic canine and loss of space were significantly related to root resorption.
- Root resorption primarily affected the apical third of the tooth roots.
Conclusions:
- Ectopic canine eruption poses a risk of severe root resorption to adjacent teeth.
- Canine position and space availability are key predictive factors.
- Early radiographic detection is essential for timely diagnosis and management.
