To investigate the parent´s knowledge and practice related to experience degree of preschool children´ s dental caries, questionnaires and oral examination_ were conducted for 312 preschool children of 3-5 years old and their parents in taegu from 1st to 30th of September, 1991.
The dft rate for 312 preschool children who were examined was 89.7%. the more´ children s age increase, the more dft rate increased with statistically significant difference(p<0.105). f rate decreased(p<0.05).
Among the parents, dft rate of parents who had known a correct knowledge on oral hygiene was increased significantly (p<0.001). dft index decreased significantly(p<0.05).
The more parent s brushing frequency increase in control of parent´ s oral hygiene, the more d rate showed significant increase (p<0.05), the more parents use a correct brushing method, the more parents make children brush tooth on time frequently and the more children who follow parent´s advice on tooth brushing well, the more dft rate and index showed significant reduction (p<0.05), the more children prefer sweet food, the more children´s sugar intake increase. the more dft rate and index increased significantly (p<0.05).The results of the stepwise multiple regression analysis on dft experience degree were as follow = the variables that have an effect on dft rate were exchanging number of deciduous teeth parent´ s knowledge on the number of deciduous teeth, children s dietary habits, children s brushing frequency and children s age_ the variables that have an effect on dft index were children s age, sex and dietary habits, the variables that have an effect´´; on d rate were parent´ s brushing frequency, children s brushing frequency and the experience of parent´ s preventive dental visits. the variables that have an effect on f rate were children´s age.
The results obtained in this study suggest that parent´ knowledge and practice on oral hygiene have a great influence on behavior on children´s oral hygiene. so the education on knowledge and practice is need for both parents and children. it is need cohort study because this study could not reveal a correct timing relationship between dft rate and factor,
