[Relationship between abnormal swallowing and mouth breathing].
OBJECTIVE
To investigate the relationship between abnormal swallowing and mouth breathing.


METHODS
Thirty-eight patients with abnormal swallowing and 38 patients with normal swallowing were selected. All patients presented with no airway constriction. The age range of the patients was 11-14 years old. The number of patients with mouth breathing was calculated. Statistical analysis (χ(2) test) was performed.


RESULTS
The number of patients with mouth breathing in the abnormal swallowing group (17, 45%) was significantly higher than that in the normal swallowing group (5, 13%) (χ(2) = 9.212, P = 0.002).


CONCLUSIONS
Abnormal swallowing was related to mouth breathing.
