The oral mode of respiration cause postural adaptations of structures in the head and neck region producing the effect on the positional relationship of the jaws.
The aim of this study is to verify the skeletal relationship of mouth and nose breathing child.
A cross sectional study was performed to assess the association of changed mode of respiration with dentofacial growth.
One hundred children among which 54 were mouth breathers and 46 were nasal breathers of 6-12 years of age were submitted to clinical examination and cephalometric radiographical analysis. Statistical analysis : Chi-square test for proportions and independent sample's "t" test for parametric data is used.
The mean values of N-Me (P<0.001) ANS-Me (P<0.001) and SN-GoGn (P<0.001) for mouth breathers is significantly higher. ArGo-GoMe (P=0.003) and (P<0.011) for 6-9 and 9-12 years age group, respectively, were significantly low in nasal breathers group.
Changed mode of respiration was associated with increased facial height, mandibular plane angle and gonial angle.
口呼吸模式会导致头颈部结构的姿势适应，从而对颌骨的位置关系产生影响。
本研究的目的是验证口呼吸儿童和鼻呼吸儿童的骨骼关系。
进行了一项横断面研究，以评估呼吸模式改变与牙颌面生长之间的关联。
对100名6至12岁的儿童进行了临床检查和头影测量X线分析，其中54名是口呼吸者，46名是鼻呼吸者。统计分析：使用比例的卡方检验和参数数据的独立样本“t”检验。
口呼吸者的N-Me（P<0.001）、ANS-Me（P<0.001）和SN-GoGn（P<0.001）的平均值显著更高。在鼻呼吸者组中，6至9岁和9至12岁年龄组的ArGo-GoMe（P=0.003）和（P<0.011）分别显著较低。
呼吸模式的改变与面部高度增加、下颌平面角和下颌角增大有关。
