The purpose of this study was to determine the effects of dental hygienists’ leader-member exchange (LMX) and empowerment on organizational performance, improve human resource management in their organization and their job satisfaction and organizational commitment, and provide basic data that could help improve organizational performance. A survey was conducted in 324 dental hygienists at dental care institutions in Ulsan, Busan, and Daegu from March 2 to 31, 2015 and the following results were obtained: Dental hygienists at dental hospitals had higher levels of LMX than those at dental clinics; those who were at higher positions, who were older, and who were more educated showed higher levels of empowerment. There was significant, positive correlation between LMX and empowerment and job satisfaction and organizational commitment: dental hygienists with better LMX and higher levels of empowerment showed higher levels of job satisfaction and organizational commitment. For dental hygienists, significance (β=0.325, p＜0.001) exerted the greatest impact on job satisfaction, followed by organizational commitment (β=0.264, p＜0.001) and competence (β=0.164, p＜0.01) and LMX (β=0.321, p＜0.001) had the greatest impact on organizational commitment, followed by job satisfaction (β=0.275, p＜0.001) and significance (β=0.210, p＜0.001).To put the results together, dental hygienists in dental care practice had their job satisfaction and organizational commitment affected by LMX and empowerment; therefore, it is necessary to develop diverse education programs with the objective of promoting mutual exchange between a manager of dental hygienists' team and members and improving empowerment.
