METHODS
transversal study.


METHODS
there were 150 children in the sample, with ages ranging from 8 to 10 years. Data was collected by means of a questionnaire and clinical examinations. As for their breathing assessment, two tests were carried out: test 1- breath steam against a mirror; and test 2 -water remains in the mouth with lips closed for 3 minutes.


RESULTS
mouth breathing prevalence was of 53.3%. There was no significant difference between gender, age and type of breathing. Facial alterations were:incomplete lip closure ( 58.8%X5,7%), fallen eyes ( 40.0%X1.4%), High palate ( 38.8%X2.9%), Anterior open bite ( 60.0% Versus 30.0%), Hypotonic lips ( 3.8%X0.0%), Circles under the eyes (97.5% Versus 77.1%).
