Abstract

A study of Córdoba's children population was made to evaluate the percentage of malocclusions and the necessity for treatrnent. 990 children of both sexes, fron first to seventh grade were chosen randomly out of the 16.870 students registered in 1993. Town Hall schools. To gather the data the epidemiological card to register malocclusions of qualitative range was used, made by the University of Dentistry of Montevideo, Uruguay, and this enabled us to determine the morphofunctional characteristics that prevail in temporary, mixed and permanent dentition. The results indicate a prevalence of abnormal lip closure and the presence of habits. The cuantitative register in mixed and permanent dentition to determine the orthodontic abnormality and evaluate the necessitty and priority of treatrnent was used in Buenos Aires by Dr. Teneban, Goto and Morales and it showed an 82% malocclusions and the highest percentage of anomalies in these teeth corresponded to the minor onea. The low percentage ofmalocclusions found in temporary dentition (19, 42%) and its increasing tendency as it evolver into permanent dentition makes us think of the necessity of regular controls from an early age to prevent and intercept malocclusions
