Introduction: Mouth breathing pattern in children may have negative physical, psychological and social effects according to the intensity and duration. The relationship between mouth breathing and sleep-disordered breathing (SDB) is derived from clinical conditions ranging in increasing severity from primary snoring, to upper airway resistance syndrome and obstructive sleep apnea syndrome. The main cause of mouth breathing and SDB is associated to narrowing of the upper airway in varying degrees. This association is of concern due to its immediate or late clinical implications like disturbances in craniofacial growth, behavioral changes, impaired learning and cognitive functions, negatively influencing quality of life. Objective: Assess the prevalence of mouth breathers (MB) and the presence of facial anatomical changes that affect children with SDB, in addition to assessing self-perceived quality of life of MB. Methodology: A cross-sectional observational sample of 687 students from public schools, aged 6-12 years old, evaluated by medical history, clinical examination and lip seal tests. Self-perceived quality of life of MB was obtained through questionnaire (Ribeiro, 2006). Results: In the total sample, 520 (75,7%) students were nasal breathers and 167 (24,3%) were MB. Among MB, 40,1% had obstructive hypertrophy of the palatine tonsils, 26,4% had Mallampati score III and IV, 35,3% has excessive overjet, 23,4% had anterior open bite, 15,6% had posterior crossbite, 53.9% had atresic palate, 35.9% had interlabial gap, 31% reported problems related to sleep and 9,0% reported having the feeling of stop breathing while asleep. Conclusion: The prevalence of facial anatomical and functional changes in mouth breathers students was high, however the self-perception of quality of life was considered good. It is recommended the adoption of public health policies aimed at diagnosis, counseling and treatment of students at this age group, in which the relief of signs and symptoms can promote normal craniofacial growth and reduce future risk of SDB.
