Study on the behavior management of children at dental treatment. Various factors affecting the frequency of training.

: Search was made using quantification method of the first and second type to search the factors affecting the frequency of training, and to estimate it. The following conclusions were led; 1. Factors giving large effect on the decision of the frequency of training were 'Frankl classification', 'ages at the initial examination' and 'if children have any experience of dental treatment or not'. 2. With the factors concerned with educational environments including mothers, 'number of brothers and sisters', 'mother's educational history' and 'if mothers works or not' showed high correlation. 3. Among the factors concerned with character analysis, 'emotional stability' 'if children can control themselves or not' gave much effect. 4. As the factors to estimate the frequency of training, the reliable factors include 'Frankl classification', 'ages at initial examination', and 'sexes'. 5. With the factors concerned with educational environments including mothers, 'mother's educational history', 'number of brothers and sisters' 'birth order' were highly reliable. 6. With the factors concerned with character analysis, 'emotional stability', 'if children fants are degenerative or productive' showed high reliability. 7. Multiple correlation coefficient for all the 27 factors was 0.823, which was found to be highly reliable for the estimation of the frequency of training.
