Material and Methods: A cross-sectional study was carried out on a sample of 399 schoolchildren between eight and eleven years old, and they were examined with the prior authorization of their parents. The examiner's calibration was performed to minimize intra-examiner variability. A kappa coefficient of 0.997 was observed for the assessment of the type of occlusion according to the criteria of Angle, Dewey and Anderson, which is a value that reflects a high degree of reliability. Results: 75.7% presented some type of dental malocclusion, showing no association with age, sex, or school of origin. Class I according to Dewey-Anderson types 1 and 2 were mostly present. Conclusion: In conclusion, it was observed that the educational level on dental malocclusion is a more decisive factor compared to the purchasing power of children...
