Abstract

For stornatoscopic study on the mouth of normal Korean. observations were made on sulcus naso-Iabialis. protrudeness of upper and lower vermilion borders. juncture line both vermilion borders. lateral view of upper lip and thickness of vermilion border in 2822 cases. Of the total cases. the 1763 cases were male and the 1059 cases were female. and ages ranged from 6 to 30. In addition. further study was made on the chronological change. difference in sexes and comparison with other races . Result of Studies: 1) Sulcus naso-Iabialis is usually obscure in the earlier ages but distinctive mostly in the grown ages. In radical comparison. Korean is more distinctive than Chinese but less than Mongolian. Distinctive cases are male 63.58±2.01% and female 57.30±2.90% obseure cases are male 36.40±2.01% and female 42.68±2.90%. 2) In protrudeness of upper and lower vermilion borders. the both borders line almost vertically. The rate of verticality is higher than Japanese. lower than Mongolian and generally same as Chinese. Vertical line cases are male 57.03±2.07% and female 56.08±2.41% upper protrusion cases are male 37.34±2.02% and female 36.54±2.14% lower protrusion cases are male 5.60±0.95% and female 7.34 ±1.53%. 3) The frontal view of mouth shows that it is mostly convex. It is slightly higher in convex than that of Chinese. Convex cases are male 62.52±2.02% and female 68.93±2.72% straight cases are male 27.80 ±1.87% and female 22.84±2.46% concave cases are male 9.66±I.23% and female 8.21±1.61 %. 4) The lateral view shows that the upper lip of Korean belongs to "Procheilie" type. "Procheilie" are male 96.32±1.04% and female 91.01±1.68% "orthocheilie" are male 6.67±1.04% and female 8.99±1.68%. 5) The thickness of vermilion border belongs to moderate form. Thick cases are male 35.30±2.00% and female 31.16±2.73% Moderate cases are male 64.50 ±2.00% and female 68.43±2.73%.
