Abstract
The purpose of this study was to evaluate child behavior and training times during dental treatment.
We examined a total number of 742 children (390 males and 352 females) aged between one and fifteen with an average of six years of age, and the following results were obtained.
1. It is difficult to adapt to dental treatment under three years of age. The r ate of adapting child in the three years of age group was 57.7%, so three years old was the turning age for adaptation during dental treatment. The adapting child increased above three years of age.
2. The average times for training in the three years of age group was two. Over three years of age, training times was decreased as the age increased.
3. In patients with nitrous oxide inhalation sedation, the training times had a tendency to be needed more than in patients without nitrous oxide inhalation sedation.
