Using Moiré topography, the forms of the dental arch and palate of males and females were compared. This was carried out in Fukien province, Taiwan. The materials used consisted of plaster casts of the upper dentitions of 65 males and 69 females with normal occlusion, aged from 20 to 22 years. The results are as follows: 1. The standard form of the upper dental arch represented by a pentagon is shown in Table 1 and in Fig. 3. 2. The dental arch of the male was larger than that of the female, the difference being significant for the anterior and posterior widths of the arch. 3. The correlation coefficients were generally lower in the female than in the male. This was especially true with regard to the size of the anterior portion of the female dental arch. In the posterior portion, there was no correlation between the dental arch length and dental arch width of either sex. 4. The distance from the origin (F) to the papilla incisiva was 23.47 mm in the male and 23.67 mm in the female. The number of moiré band in the bottom of the palate at the origin from the basal plane was 12.89 in the male and 12.73 in the female. There were no significant differences in these two measurements between sexes. 5. On the vertical section of the palate, the anterior portion of the palate of the female was deeper than the male. However, in the posterior portion the male was deeper and wider in the palate morphology than the female. The vertical section in the palate of the male was similar in form to that of the female at the midpoint between the anterior and posterior portions, the canine and/or first premolar. 6. The horizontal section of the palate showed that the distance from the origin to the canine and/or to the first premolar were similar in both sexes at any palate depth.
利用莫尔条纹地形术，对男性和女性的牙弓及腭部形态进行了比较。这项研究在台湾省福建地区开展。所用材料包括65名年龄在20至22岁、咬合正常的男性以及69名年龄在20至22岁、咬合正常的女性的上牙列石膏模型。结果如下：1. 由五边形表示的上牙弓标准形态见表1和图3。2. 男性的牙弓比女性的大，牙弓前后宽度的差异具有显著性。3. 女性的相关系数总体上低于男性。在女性牙弓前部尺寸方面尤其如此。在后部，男女牙弓长度与牙弓宽度之间均无相关性。4. 男性从原点（F）到切牙乳头的距离为23.47毫米，女性为23.67毫米。男性从基平面起在腭部底部的莫尔条纹数量为12.89，女性为12.73。这两项测量在性别之间无显著差异。5. 在腭部垂直截面中，女性腭部前部比男性深。然而，在后部，男性腭部形态比女性更深且更宽。男性腭部垂直截面在前后部中点、尖牙和/或第一前磨牙处的形态与女性相似。6. 腭部水平截面显示，在任何腭部深度，男女从原点到尖牙和/或到第一前磨牙的距离相似。
