Introduction: This study aimed to determine the prevalence of occlusion abnormalities and their relation to oral habits at an educational institution. Methods: cross-sectional study involving 217 schoolchildren at the Camino de Paz school (Llanaditas, Comuna 8, Medellin). Using clinical examinations, socio-demographic variables were collected along with occlusion-related variables, occlusal relationship type (angle), the presence of diverset oral habits, a description of the frequencies and calculation of the prevalence ratios (pr), with confidence intervals of 95% (95% ci) by gender.

Results: The study population contained a greater proportion of class i, except in the group of 11-12 year-olds (class ii). In more than half, their dental midlines do not match. Nearly one quarter of the boys and 15% of the girls had deep anterior bite; other abnormalities accounted for less than 10%. The most common oral habits in the children were onychophagia, putting objects in their mouths and lip-biting. There were differences in oral habits according to the molar relationship and gender.

Conclusions: There is an association between occlusion alterations and the presence of oral habits, according to gender, which requires further analysis to establish causal relationships.

Keywords: angle classification, habits, malocclusion, dental occlusion.
