Objective: To determine the risk of early impaction of maxillary canines through panoramic radiography in children with mixed dentition stage who attended the Santo Tomás de Floridablanca University clinics in the period from 2018 to 2020.
Materials and methods: An analytic study was carried out, descriptive cross section; analyzing the variables: age, sex; mixed dentition stage and nolla stage of maxillary canine; to determine the risk of impaction of the maxillary canine; using panoramic radiography, the Ericson and Kurol method was used; in which, if the canine was in position 4 or 5, the alpha angle was greater than 25 °, the beta angle was greater than 35.6 ° or the distance from the cusp of the canine to the occlusal plane was greater than 18.46 mm, the tooth was considered to be at risk for early impaction. This study was classified as risk-free research and was approved by the Santo Tomás University Ethics Committee.
Results: 171 X-rays of boys and girls aged 9.3 ± 1.1 years were evaluated; 56.7% of the participants were girls. The most frequent nolla stage in the investigation was 2/3 root formation; with 47.6% and the position according to Ericson and Kurol was 1 in 89.4%. The children who were at risk of impaction were 9.7 ± 1.0 years old on average. The majority of teeth at risk of impaction were in the second transitional period with 51.7% and those without risk of impaction were in the intertransitional period with 66.2% (p = 0.010).
Conclusions: The risk of early impaction of maxillary canines was diagnosed in 10.8% of the canines evaluated by means of panoramic radiography, which indicates the need for an early diagnosis.
