한국인 성인 사악측절치의 석고모형과 발거치야에서 순면, 절단연, 절단우각, 설면의 형태를 조사하였고 치아의 크기를 계측하여 Wheeler의 수치와 비교하였다. 순면의 형태는 중앙업의 발육이 중등도로 뚜렷한 치아가 가장 많았고 절단인의 형태는 절단인이 둥근 치아가 가장 많았으며, 절단우각의 형태는 원심절단우각이 근심절단우각보다 중등도로 완치아가 가장많았다. 치아의 크기는 남녀 각각 치관장은 9.9㎜. 9.4㎜, 치관폭은 7.0㎜ 6.8㎜ 치경부치관 폭은 5.5㎜ 5.2㎜ 치관후는 6.5㎜ 6.2㎜ 치경부치관후는 6.1㎜ 5.9㎜ 치경부 근심만곡은 2.5㎜ 2.1㎜ 치경부 원심만곡은 2.0㎜ 1.8㎜이 었다.

Authors examined the morpbology and size the maxillary lateral incisor from Korean adults and the following cinclusions have been drawn. 1.In the shapes of labial surface in maxillary lateral incisorsm, the quite promient middle lobe, Moderate prominent middle lobe, less prominent middle libe were 20.60％. 69.85％ 9.55％ respectively. 2.In the shapes of incisal angle in maxillary lateral incisors the equal sized mesioincisal angle and distioncisal angle, larger distioncisal angle, mach larger distioncisal angle were 8.36％ 67.34％ 24.30％ respeetively 3.In the shapes of incisal angle in maxillary lateral incisors, the equal sized mesioincisal angle and distoincisal angle, larger distoincisal angle much larger distoincisal angle were 8.36％ 67.34％ 34.30％ respectively 4.In the shapes of lingual surface maxillary lateral incisors the marked shovel(Ms), semi-shovel(Ss), trace shovel(TS), no shoovel(No) were 43.00％ 33.50％ 19.50％ 4.00％ respecively 5.The sized of the maxillary lateral incisors were as follows. 6.In comparison with Wheeler`s data, crown length, crown width and crown thickness were larger in Korean adult,but the degrees of cervical curvature were smaller
