Abstract
To evaluate the prevalence of ectopic eruption of the permanent maxillary canine in patients 6 to 10 years of age and its relationship to other dental anomalies, age and sex of the patient. Study design: Descriptive, cross-sectional, observational, and retrospective study METHODS: A total of 260 panoramic radiographs were collected from patients who had their first visit at the Paediatric Dentistry Department of the Hospital HM Nens, HM Hospitals in Barcelona from January to May 2021. The prevalence of ectopic eruption was evaluated based on the following variables: age, sex, inclination angle and mesiodistal position of the crown of the permanent maxillary canine. Additionally, the presence of other dental anomalies was recorded. The statistical analysis to evaluate the relationship between two categorical variables was carried out using the Chi-square (or Fisher) test with unrelated samples and the Mann-Whitney test with related samples. A p-value of 0.05 and a 95% reliability level were considered statistically significant. The prevalence of ectopic eruption of the permanent maxillary canine was 9.23%. In this sample, no relationship was found between patients with maxillary canine with abnormal position and inclination and the presence of other dental anomalies.
