Abstract: Authors examined the morphology and size in the maxillary lateral insicor from Korean adults and the following conclusion have been drawn. 1. In the shapes of labial surface in maxillary lateral incisors, the quite prominent middle lobe, moderate prominent middle lobe, less prominent midd1e lobe were 20.60%, 69.85%, 9.55%, respectively. 2. In the shapes of incisal margin in maxillary lateral incisors, the arc shaped to the distal, round, nearly straight were 24.96%, 60.20%, 15.11%, respectively. 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%, 24.30%, respectively. 4. In the shapes of lingual surface in maxillary lateral incisors, the marked shovel (Ms), semi-shovel (Ss), trace shovel (Ts), no shovel (No) were 43.00%, 33.50%, 19.50%, 4.00%, respectively. 5. The size 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 degree of cervical curvature were smallest.
