Malocclusions, according to the World Health Organization (WHO), rank third as oral health problems. The aim of this research work was to determine the frequency of malocclusion present in 6 to 12 years old children in the city of Coronel Oviedo, Paraguay in 2016.A descriptive observational study with analytic component was performed in the children that had the first permanent upper and lower molar in at least one hemiarch, who presented the informed consent signed by the parents. The outcomes were malocclusion, molar and canine relation, overjet and overbite, crowding and crossbite. The data was loaded into an Excel spreadsheet and analyzed with the Stata 14 program. Malocclusion was found in 66% of the children, 85.7% presented molar and canine Class I, 44.6% normal overbite, 35.7% normal overjet, 55.4% crowding, 8.9% presented crossbite, 75% straight profile, 62.5% deviation from the midline. In relation to age (p=3.2) and sex (p=0.4), no statistically significant associations were found in relation with malocclusion. The frequency of malocclusion in schoolchildren from Coronel Oviedo, Paraguay was high.
