Correlation between otitis media and dental malocclusin in children

AIM: To determine the possible correlation between otitis media and dental malocclusion in children. METHODS: Fifty subjects (26 males and 24 females; mean age: 7.8 ± 1 years) were assessed: 25 patients, with otitis media formed the study group, while 25 healthy subjects formed the control group. An otolaryngological examination and dental cast measurements were performed in order to evaluate adenoids, tonsils and dental relationships, respectively. RESULTS: A significant correlation (p<0.05) was found between otitis media and enlargement of adenoids (13 patients, 52% in the study group) and tonsils (11 patients, 44% in the study group). Furthermore, a significant predominance (p<0.05) of posterior cross-bite was found in the study group (19 children, 76%), in comparison to the control group (4 children, 16%). No correlation between otitis media and overjet, overbite, Angle Class relationship, or inadequate oral habits were found. CONCLUSIONS: Posterior cross-bite and adenoidstonsils enlargement are factors significantly associated with otitis media in children.
