Objectives. A survey was conducted to determine if students underwent changes in their health and belief. The subjects used for analysis included 30 students in the experimental group and 41 students in the control group. Methods. To verify differences between the experimental and the control groups, ANOVA was carried out before and after the program. Results. 1. After the program, the left and right final RULA scores of the experimental group decreased from 5.24 to 4.48 during the operation on the upper and lower jaws. 2. The scores for sensitivity, severity and benefit of health-belief increased after the program. The increase in the scores of the experiment group was significant, compared with that of the control group (p＜0.05). 3. Before the program, the waist was the most painful body part for both the experimental and the control groups, with scores of 3.10±1.29, 3.06±1.2. For the experimental group, the order of pain severity following the waist was the shoulder, neck, back and hand. After the program, the order of pain severity following the waist was the neck, shoulder and waist for the experimental group, In contrast, the order of pain severity for the control group was the shoulder, neck and waist. Conclusions. The results of this study indicate the MSD prevention education program is effective in preventing the disorder. Thus, this program can be utilized as an education program for preventing MSDs during dental hygiene students` oral prophylaxis practice and clinical practice.
