The aim of this study was to investigate the temporomandibular, craniofacial and postural changes associated with mouth breathing and also evaluate the relationship between clinical signs and SDB symptoms in children 7 to 14 years of age. A case-control study with a sample of 147 children, 73 mouth breathers (MB) and 74 nasal breathers (NB), were evaluated by anamnesis, clinical examination and respiratory tests. The schoolchildren diagnosed as MB answered a questionnaire on self-perceived symptoms of SDB, focusing on the masticatory system, nasal and sleep problems. The presence of mouth breathing was statistically significant with the following changes: a lack of lip seal (OR=29.70), a deviation during the opening of the mouth (OR=24.63), an atresic palate (OR=5.07), a facial asymmetry (OR=5.06), an obstructive Mallampati scores (OR=2.85), a Class II malocclusion (OR=2.67) and a turbinate hypertrophy (OR=2.19). No significant difference in postural pattern was found between groups. In the MB group, TMJ problems and wake up with headache were associated with a Class II malocclusion and a lack of lip seal. Stiff neck or neck pain were associated with an altered overbite and a forward head position. Sleep problems, daytime sleepiness, waking at night, snoring and sleeping with the mouth open were associated with a tonsillar hypertrophy and obstructive Mallampati scores. The chances of occurrence of temporomandibular and craniofacial changes were high in the MB schoolchildren. The emergence of the SDB symptoms in childhood appears to be associated with the persistency of the mouth breathing and their consequent craniofacial, occlusal, postural and upper airway s abnormalities.
