Backround: 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. Aim: The aim of this study is to verify the skeletal relationship of mouth and nose breathing child. Study design: A cross sectional study was performed to assess the association of changed mode of respiration with dentofacial growth. Materials and Methods : 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. Result: 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. Conclusions: Changed mode of respiration was associated with increased facial height, mandibular plane angle and gonial angle.
