Skeletal and occlusal characteristics in mouth-breathing pre-school children

This study verified the influence of chronic mouth breathing on dentofacial growth and developmental in

pre-school children.The study evaluated 73 children, both sexes, ranging from 3 to 6 years of age.After the

otorhinolaryngological breathing diagnosis, 44 mouth-breathing children and 29 nasal-breathing children

were compared according to facial and occlusal characteristics. The skeletal pattern measurements

SN.GoGn,BaN.PtGn,PP.PM,Ar-Go, S-Go indicated a tendency to mouth-breathing children presenting

a dolicofacial pattern. According to occlusal characteristics, only the intermolar distance showed a significant

correlation with a narrow maxillary arch in mouth-breathing subjects. Based on the results of this

study, mouth-breathing can influence craniofacial and occlusal development early in childhood.
