Objectives : The purpose of this study was to investigate the relationship between the degree of family support and the degree of satisfaction in clinical practice by dental hygiene students. Methods : In this study, convenience sampling was conducted in 272 dental hygiene students from 3 dental hygiene colleges in South Jeolla Province, from October 4 through 15, 2010. A survey was conducted by using structured questionnaires. The data was analyzed by t-test, a one way ANOVA, and Pearson correlation coefficient. Results : Family support according to general characteristics showed a significant difference by economic status(p<0.001), satisfaction of major(p<0.01), and interpersonal relationship(p<0.05). Satisfaction degree on clinical practice according to general characteristics showed a significant difference by satisfaction of major(p<0.05) and interpersonal relationship(p<0.05). The relationship between generally perceived family support correlated with the degree of satisfaction in clinical practice(r=.154, p<0.05). Conclusions : It was found that a higher degree of satisfaction in clinical practice depends on a higher degree of family support. Therefore it is required to program development to improve satisfaction level of clinical practice by family support.
