Introduction: the act of breathing is very importance to stimulate and maintain the balance of the stomatognathic system. Objective: to assess the repercussion of mouth breathing in children from 9 to 12 years old belonging to "Ormani Arenado" Dentistry Clinic, Pinar del Rio. Material and method: a descriptive and cross-sectional study was carried out during 2012. Target group: all children from 9 to 12 years old. Sample: 197 children chosen by means of a simple-at random sampling. Variables: age, type of breathing, malocclusion, occlusion anomaly, palatal depth and facial type, using measures to sum-up the qualitative variables (absolute frequency and percentages); along with measures of central trends (mean and standard deviation), to the process the quantitative variables. Chi square test was used to determine the influence of the type of breathing with malocclusion; and Student-T test was included in the case of projection and palatal depth variables. Results: 27,4% of patients showed the pattern of mouth breathers, the highest representation belonged to the group of 10 years old (35,2%). In this group a determined cause was identified on 61,1% of the patients; 98,1% presented malocclusion, prevailing Category II; the most frequent anomaly of malocclusion was the enlarged projection and a minor prevalence of dolichofacial type. Conclusions: a strong association was observed among breathing, malocclusion and facial types.
