The purpose of this study was to establish a set of standard values for the form of the nose and its relationship to other croniofacial structures in young korean adults in angle`s class I occlusion. The subjects were 40 (20 male, 20 female) Korean dental students in angles class I occlusion. Lateral cephalometric radiographs were used to determine the form of the nose and its positon relative to other craniofacial structures. The results were obtained as followed. 1. There was a significance between the registered male and female measurements in nasal height(P<0.05). (Male: 58.23m Female : 54.62mm) 2. There was a significance between the registered male and female measurements in nasal length(P<0.05). (Male : 54.18ea Female : 49.38me) 3. The vertical distances from the tip of the nose in Korean adults were significantly greater in the male(P<0.05) and were smaller in both sex in comparison with caucasian.
