ABSTRACT
Objectives@#This study aims to determine the influence of social exchange relationships, leader’s political skills, job stress, job satisfaction, and organizational commitment on turnover intention among dental hospital hygienists. @*Methods@#A self-administrated questionnaire survey was conducted from April 1-May 12, 2020, involving 209 dental hospital hygienists in Seoul, Busan, and Gyeongnam. The collected data were analyzed using SPSS and AMOS statistical analysis programs. @*Results@#In the hypotheses testing, 9 of 18 hypotheses were supported. In social exchange relationships, job stress, job satisfaction, and organizational commitment, the path to turnover intention had a significant effect, but it was not statistically significant in leader’s political skills. With regard to mediating effect, job stress, job satisfaction, and organizational commitment played a complete mediating role in the path from social exchange relationships to turnover intention. @*Conclusions@#To increase job satisfaction and organizational commitment, and lower job stress in order to have a positive impact on turnover intentions, it is imperative to develop and apply a program to enhance social exchange relationships.

ABSTRACT
This study identified an effective control method for periodontitis by investigating the association between blood levels of vitamin D and periodontitis in Korean elderly based on raw data from the fifth Korea National Health & Nutrition Examination Survey of 2010 (KNHANES). In this study, 1,021 adults over 65 years of age were evaluated based on data from the KNHANES. Periodontal disease was assessed using community periodontal index (CPI), with CPI codes ≥3 defined as periodontitis. Blood levels of vitamin D were measured from blood samples and divided into four groups (first quartile: ≤13.23 ng/ml, second quartile: 13.24∼16.95 ng/ml, third quartile: 16.96∼21.58 ng/ml), and fourth quartile >21.59 ng/ml). Using multiple logistic regression analyses, the variables were adjusted for general characteristics, oral health-related characteristics, health-related characteristics, and bone mineral density. The statistical analysis was performed using the SAS (ver. 9.2). The results of this study are as follows: the prevalence of periodontitis was 42.6% in Korean elderly. After adjusting for general, oral health-related, and health-related, the risk of periodontitis in the first quartile group was 1.74 times (95% confidence interval [CI], 1.02∼2.98) higher than that of the fourth quartile group (p=0.041). After adjusting for general, oral health-related, and health-related characteristics as well as bone mineral density, the risk of periodontitis in the first quartile group was 1.73 times (95% CI, 1.02∼2.96) higher than that of the four quartile group (p=0.042). There was a significant relationship between blood vitamin D level and periodontitis in Korean elderly. For the prevention of periodontitis, factors related to vitamin D should be considered along with other risk factors.
