PURPOSE: The purpose of this study was to evaluate mouth-breathing and nasal-breathing children prior to surgical intervention and 28 months postoperatively, comparing the occlusal features obtained pre- and postoperatively through orthodontic study casts.
METHODS: The mouth-breathing (MB) group consists of 33 MB children who underwent surgery and presented a nasal-breathing (NB) pattern after surgery. The control group comprised 22 NB children. The orthodontic examinations were accomplished prior to surgery (T1) and an average of 28 months postoperatively (T2).
RESULTS: At T1, the MB and NB children presented no statistically significant difference in any analyzed occlusal features and measurements. At T2, the MB presented larger overjet comparing to NB children (P<.05). MB and NB groups presented statistically similar results (P>.05) concerning intercanine and intermolar distances, second primary molar terminal plane and canine relationship, overbite, crossbite, and open bite. From T1 to T2, the MB and NB groups showed a statistically significant difference in the molar terminal plane.
CONCLUSION: Neither the breathing pattern nor the surgery had any effect on occlusal features in 3- to 6- year-olds.
