The author studied the state of sagittal canine relationship, sagittal molar relationship and spacing in 3-6 years old, 172 children (on plaste model).
The results were as follows
1. In sagittal canine relationship, 72 children (41.9%.) showed same plane, 38 children (22.1%) showed distal step, 20 children (11.6) inesial step and 42 children (24.4%) showed unilaterally.
2. In sagittal molar relationship, 82 children (47.7%) showed same vertical plane, 6 children (3.5%) showed distal step, 42 children (24.4%) showed mesial step and 42 children (24.4%) showed unilaterally.
3. Most of primate spaces are less than 1mm. 37 children (21.5 % ) in upper arch, and 40 children (23.3%) in lower arch showed no primate space.
4. The frequence of interdental spacing showed that primate space with other spaces was appeared most frequent.
