Objectives: Although dental hygienists are professional workers, their job retention is short.
Therefore, in order to improve job retention, the relationship between professional identity and professional self-concept was analyzed. Methods: From January 1 to April 30, 2020, 155 dental hygienists were examined. For data analysis, multiple regression analysis was conducted to confirm the effects of professional identity and professional self-concept on job retention. Results: The dental hygienist's professional self-concept was significantly higher in the team manager than in the staff, but the professional identity was not significantly different. Dental hygienists' professional identity, professional self-concept, and job retention were all positively correlated (p<0.05). As a factor influencing dental hygienist's job retention, the self-concept of the profession had a significant effect, but the identity of the profession did not. Conclusions: Since the professional self-concept has a positive effect on maintaining the profession of dental hygienists, it is necessary to make efforts to improve the professional self-concept in order to increase the job retention.
