Introduction: malocclusions are one of the main conditions of the oral cavity, ranks third in order of most prevalent. Malocclusions can cause a tooth, but they are anomalies in the size of the maxillary macrognatismo, micrognatismo and abnormal position of the jaws with respect to the cranial base prognathism, retrognathia, anterorrotación and the mandibular posterorrotación caused by most severe malocclusions, skeletal malocclusions.
Objective: To describe the frequency and distribution of dental and skeletal malocclusions in a child population of 6 to 15 years attending a dental clinic multidisciplinary Saragossa.
Materials and Methods: We conducted an epidemiological study classified as observational, descriptive, cross prolectivo . The study population consisted of 156 patients with an average age of 10.2 (± 2.1) Minimum 6, maximum. The clinical assessment of dental malocclusions was carried out with the Angle classification and the analysis of skeletal Steiner.
Results: The most frequent malocclusion in this study was distoclussion in 27% of the population (n = 42), the skeletal class II with 58.3% (n = 91) and III only in 5.8% (n = 9 ) of the study population. The frequency of Class III age was 1 case of 2 and 7 years of age 9,11,12 and 13. Class II is predominant in the Mexican population according to the literature, ours.
Conclusions: Within our results we can see that the skeletal Class II is the most prevalent. What is serious is that this alteration is associated with mouth breathing problems, and narrow maxillary lingual malpositions, among others.
