RESUMO
There are several controversies on the real interference from breathing on craniofacial growth. This study evaluated the possible relationship of the influence of breathing pattern with cephalometric variables: 1) sagittal skeletal variables: convexity of point A, facial depth, maxillary depth and mandibular body length; 2) vertical skeletal variables: lower facial height, facial axis, facial cone, palatal plane, mandibular plane, posterior facial height and mandibular arch; 3) dental variables: protrusion of mandibular incisor and protrusion of maxillary incisor. The sample was composed of 120 children, males and females, with Class I and II-1 malocclusions, mouth breathers and nose breathers, in the mixed and permanent dentition stages, with indication for orthodontic treatment. After orthodontic, ENT and speech evaluations, the sample was divided into 2 groups: 60 children with Class I and II-1 malocclusion, mouth breathers, and 60 children with Class I and II-1 malocclusion, nose breathers; each group was further divided into 3 subgroups according to age range, namely 7 to 8 years, 9 to 10 years, and 11 to 12 years. After achievement of results and interpretation of statistical analysis, the following could be concluded: 1) concerning the relationship between breathing patterns and sagittal skeletal variables, there was statistically significant difference with increase in the following cephalometric variables: convexity of point A for mouth breathers aged 7-8 years with Class I malocclusion; and facial depth and maxillary depth for mouth breathers aged 9-10 years with Class II-1 malocclusion; 2) concerning the relationship between breathing patterns and vertical skeletal variables, there was statistically significant difference with reduction in the following cephalometric variables: facial cone for the mouth breathers aged 9-10 years with Class I malocclusion; and mandibular arch for the mouth breathers aged 7-8 years with Class II-1 malocclusion; 3) concerning the relationship between breathing patterns and dental variables, there was no statistically significant difference for protrusion of either maxillary or mandibular incisors, without correlation with breathing patterns (mouth and nose breathing).
