Objectives : The purpose of this study was to investigate the relationship between the resilience and organizational commitment of dental hygienists for the improvement of organizational performance. Methods : A self-reported questionnaire was filled out by 323 dental hygienists from May 2 to June 5, 2014. The collected data were analyzed by a statistical package SPSS WIN 12.0. Results : The dental hygienists had the highest score in relationship(4.09), and had the lowest score in communicative competence(3.29). In organizational commitment, they had the highest score in affective commitment(3.20). There were statistically significant differences in that regard according to age(p<0.001), marital status(p<0.05) and career(p<0.001). The organizational commitment varied significantly with age(p<0.05) and career(p<0.01), and normative commitment significantly varied with the number of work days(p<0.05) and career(p<0.05). There was a significant correlation between the resilience and organizational commitment of the dental hygienists(p<0.001). Conclusions : The organizational commitment of the dental hygienists was better when they had a better resilience, and that resilience made a contribution to the improvement of organizational commitment in the clinical dental hygienists.
