Data were analyzed for anxiety, stress and fatigue, general characteristics using SPSS 18.0 program for descriptive statistics, ANOVA, and correlation. Results : Saliva suction showed the most high score in treatment(<TEX>$mean{\pm}SD=2.92{\pm}1.13$</TEX>) and was followed by children dental care(<TEX>$2.79{\pm}1.21$</TEX>), preventive dental care(<TEX>$2.38{\pm}1.04$</TEX>), maxillofacial radiology(<TEX>$2.35{\pm}1.15$</TEX>). During the clinical practice, students felt uneasy when they stayed in relative home(p<0.05). Poor interpersonal relation(p<0.001), poor health condition(p<0.01), low satisfaction with major(p<0.01), the other cause of major choice(p<0.01) influenced on their stress. Satisfaction with major was closely related to clinical practice performance, anxiety, physical fatigue and mental fatigue.
