Abstract
The purpose of this study is to analyze the changes of arch circumferences during the deciduous dentition period. 600 stone models of maxillary and mandibular arches obtained from the children aged 3,4, or 5 years were under measurement. 1. Arch circumferences increase with age both in males and in females. 2. Arch circumferences of males are longer than females at the age of 4 and 5, but no notable differences at the age of 3. 3. Arch circumferences of upper arches are longer than those of lower arches.
