The purpose of this study was to examine the size, form of dental arch and occlusion type in college students in our country and the relationshipof the factors. The subjects in this study were 210 selected dental hygiene students. The collected data were analyzed by a statistical packagePASW 18.0. When their size, form and occlusion of dental arch were analyzed, the inter-canine width of the maxillary was 34.38 mm, and theinter-first molar width was 52.05 mm. The canine depth was 8.60 mm, and the first molar depth was 28.69 mm. As for the mandibular, theinter-canine width was 26.42 mm, and the inter-first molar width was 44.83 mm. The canine depth was 5.54 mm, and the first molar depth was24.38 mm. Concerning the form of dental arch, the percentage of normal dental arch in the maxillary stood at 29.0, and that of crowding stoodat 60.5. The percentage of spacing stood at 10.5. In the case of the mandibular, the percentage of normal dental arch stood at 29.0; crowding,55.7; and spacing, 15.2. In relation to occlusion, the percentage of normal occlusion stood at 16.7. As to malocclusion, class I that accounted for55.7 was most common, and class II and class III respectively accounted for 20.5 and 7.1. When the size of dental arch was compared accordingto the form and occlusion of it, dental arch was largest (45.95 mm) in size when the form of dental arch in the inter-first molar width of the mandibularwas spacing. The size of dental arch was 44.73 mm when its form in the same region was normal, and that was 44.58 mm when its form in thesame region was crowding (p=0.032). Regarding the relationship between the form and occlusion of dental arch, crowding was most commonwhen there were class I, II and III of malocclusion both in the maxillary and mandibular.
