BACKGROUND: The aim of this study was to evaluate the awareness of occupational hazards and personal protective equipment use among dental hygienists (DHs).METHODS: A total of 271 self-administered questionnaires were obtained from 280 DHs working at dental hospitals or clinics in Daegu and Gyeongsangbuk-do, Korea.RESULTS: The occupational hazards included work involving dust (94.1%), volatile substances (86.0%), noise (97.0%), and light-curing units (96.7%). The proportion of dental hygiene tasks that participants perceived as harmful were 42.4%, 51.7%, 9.2%, and 31.4% in the same order as above. The proportion of participants who used dust-proof masks during work involving dust was 1.1%. Those who wore gas-proof masks and gloves for work using volatile substances were 0.7% and 31.2%, respectively. Participants who used goggles for work involving light-curing units were 31.0%. None of the participants used ear plugs for work involving noise. A total of 22.9% of the participants recognized the Material Safety Data Sheet, while 79.7% had never been educated about harmful work environments.CONCLUSION: When compared to exposure status and perception of occupational hazards, the level of protective equipment use was very low. Extra measures to increase DHs’ use of personal protective equipment are necessary.

Analysis of Factors Affecting the Quality of Work Life of Dental Hygienists Based on the Culture-Work-Health Model / 치위생과학회지

This study investigated the relationship between the organizational culture, organizational support, organizational health, personal health, and quality of work life of dental hygienists and analyzed the factors affecting the quality of work life in order to identify ways to improve their quality of work life. A total of 320 dental hygienists completed a self-administered survey; after excluding data from 21 respondents, 299 responses were included in the analysis. Frequency analyses, t-tests, one-way analysis of variation (ANOVA), and correlation analyses were conducted. A path analysis was also conducted to confirm the causal relationships. The findings are as follows. First, there was a significant difference in several general characteristics of the organizational culture including years in the current job and the number of dental hygienists; organizational support including age and the number of dental hygienists; organizational health including years in the current job and annual salary; and personal health including annual salary. Second, the quality of work life showed a positive correlation with organizational culture, organizational support, personal health, and organizational health in that order. Third, the results of path analysis revealed that organizational culture had a positive effect on organizational support; organizational support and personal health on organizational health; organizational support on personal health; and organizational support and organizational health on quality of work life. In addition, organizational support and organizational health had a direct effect on the quality of work life, while organizational culture, organizational support, and personal health had an indirect effect. These results indicated existence of a relationship among organizational culture, organizational support, organizational health, personal health, and quality of work life. It is necessary to identify ways to improve the quality of work life of dental hygienists.

Factors Affecting the Turnover Intention of Dental Hygienists: Emotional Labor, Job Satisfaction, and Social Support / 치위생과학회지

This study aims to contribute to managing the human resource of dental hygienists and qualitatively enhancing dental medical services by examining factors that affect their turnover intention. Therefore, it attempted to examine their degrees of emotional labor, job satisfaction, and social support and the effects of each variable on turnover intention. This study administered self-reporting questionnaires to dental hygienists working in dental hospitals, dental clinics, and general or university hospitals in Seoul Metropolis and Gyeonggi-do by conducting convenience sampling, from May 18, 2017 to August 4, 2017. Among a total of 224 copies that were distributed, a total of 223 copies, excluding 1 copy with poor responses, were used in the data analysis. The research tools comprised 12 questions on general characteristics, 24 questions on emotional labor (4-point Likert scale), 16 questions on job satisfaction (5-point Likert scale), 8 questions on social support (4-point Likert scale), and 4 questions on turnover (5-point Likert scale). The scores of dental hygienists were as follows: emotional labor, 2.49 out of 4; job satisfaction, 3.14 out of 5; social support, 3.04 out of 4; and turnover intention, 3.07 out of 5. Their turnover intention has a positive correlation with emotional labor, but a negative correlation with job satisfaction and social support. It was found that some factors that significantly influence turnover intention included the amount of overtime work and job satisfaction. Thus, dental medical institutes should search for measures, including improvement of the working environment, to reduce the amount of overtime work and enhance job satisfaction.

Validity and Reliability of a Tool Measuring Long-Term Employment Factors among Dental Hygienists / 치위생과학회지

Dental hygienists are important members of any dental clinic. They are recognized as reflecting the dental clinic's image because they spend a lot of time with patients. The longer the dental hygienist is employed, the better the relationship with the patients and the medical service provided. The purpose of the present study was to develop a scale to measure factors of long-term employment among dental hygienists. The basic questions were constructed by analyzing tools used to measure job embeddedness and satisfaction. Forty-one questions were developed that measured organizational fit (13), interpersonal relationships (8), job satisfaction (7), duty satisfaction (6), recognition (4), and self-esteem (3). A questionnaire survey was conducted, and the responses from 297 dental hygienists in dental clinics, after the exclusion of 20 incomplete surveys, were used for the exploratory and confirmatory factor analyses. As revealed by exploratory factor analysis, long-term employment intention was composed of 7 factors consisting of 29 items after the exclusion of 12. The subsequent confirmatory factor analysis revealed 4 factors (“organizational fit,”“professional identity,”“job connectivity,” and “interpersonal relationship”) consisting of 16 items, after the exclusion of 13. Cronbach's α were 0806, 0.836, 0.700, and 0.684 for the four factors. This study is meaningful in that it developed a long-term employment factor measurement tool that can be applied to domestic dental hygienists. Future studies will need to focus more on professional identity and job outcomes. The results of this study and future related ones could be used to improve dental hygienist's continuous service.

Impact of Dentists' Attitudes and Dental Hygienists' Services on Dental Anxiety / 치위생과학회지

The purpose of this study was to investigate the factors affecting dentists' attitudes and dental hygienists' services on dental anxiety in adults. The subjects were 300 adults older than 20 years of age living in Seoul, Gyeonggi, Daejeon, and Daegu. Data were collected using structured questionnaires. Among the distributed questionnaires, 225 respondents were selected as subjects, excluding 74 people who did not answer and 1 person who was not faithful. Data were analyzed using statistical software with a t-test, one-way ANOVA, and multiple regression. As a result, the gender was slightly higher in women (54.7%) than in men, and the last dental visit was less than one year in 59.6% of respondents. Most of the respondents' educational level was higher than college level (79.1%), and the monthly income was less than 2 million won in 53.8 of respondents. This study showed that distrust of dentists affected dental anxiety and anxiety stimulation. Higher reliability of the dentist was correlated with less dental anxiety in patients. Dental anxiety showed statistically significant results in dentist subcategories of patient slight and dentists' trust (p < 0.01). Additionally, the factors affecting dental anxiety and anxiety stimulus were knowledge of dental hygienist and distrust of dentist (p < 0.01). According to this study, dentists' and dental hygienists' trust of dental staff show the importance of oral health professionals' role in reducing dental anxiety in patients. It is also suggested that efforts should be made to improve public awareness of oral health experts. It is believed that dentists, and dental hygienists need to promoted to become professionals. In addition, a variety of programs have been developed to reduce dental anxiety, so patients need to be comfortable to receive dental treatment.

A Qualitative Research on Role Conflict Experiences of Clinical Dental Hygienists / 치위생과학회지

This study was based on the experience of dental hygienists' role conflict, and attempted to grasp the nature of the dental hygienist role conflict factor, constituent factor and coping. Giorgi's phenomenological method was used to analyze data collected through in-depth interviews with nine dental hygienists working in a dental clinic. The analysis revealed three central meanings: task scope, role conflicts, and role conflict management style and limitations. In the first category, task scope, the range of the legal scope, and the duties performed by the dental hygienist differed slightly. The second category included role conflict due to interpersonal relationship, work, work environment, competence, and identity as a professional because of role conflict. The third category included the role conflict management style and limitations. Dental hygienists tried to solve the role conflict situation through various efforts. In the face of the reality that the conflict is not solved despite such efforts, the dental hygienists felt the limitation and chose to leave. Dental hygienists are dissatisfied with their roles because of confusion regarding professional values and lack of awareness of the professional workforce due to differences between legal scope and actual practice. Based on the results of this study, it is necessary to develop a tool to quantitatively measure the level of role conflict in dental hygienists and to conduct follow-up studies on the effects of coping strategies by role conflict situations.

Influence of Some Commercially Available Mouthwashes on Teeth / 치위생과학회지

The purpose of this study was to investigate the chemical properties of some commercially available mouthwashes and to ascertain whether the mouthwashes accelerated mineral loss in dental enamel. Five commercially available mouthwashes were selected from the three largest malls in Korea: Perio Total 7 Aqua Cool Mint Strong FreshTM (PS; LG Household & Health Care Ltd.), Garglin OriginalTM (Dong-A Pharmaceutical Co., Ltd.), Garglin ZeroTM (Dong-A Pharmaceutical Co., Ltd.), Listerine Naturals CitrusTM (LC; IDS Manufacturing Ltd.), and Listerine Cool MintTM (LM; IDS Manufacturing Ltd.). The composition, pH, and titratable acidity of the mouthwashes were investigated. Six bovine teeth specimens were prepared for each mouthwash group. Each of the six specimens was individually immersed in 30 ml aliquots of mouthwash for 1 minute, 30 minutes, 90 minutes, and 120 minutes, and the samples were placed in a 36.5℃ stirred incubator. The degree of mineral loss (ΔF) of the tooth surface area exposed to mouthwash, compared with normal teeth, was analyzed by quantitative light-induced fluorescence-digital. The difference in ΔF among mouthwash groups was examined by the Kruskal-Wallis H test (α=0.05). The contents of mouthwashes differed between Listerine and other products, and the pH ranged from 4.09 to 6.75. The titratable acidity of PS was the lowest at 0.63 ml and highest at 9.25 ml for LM. Minor mineral loss was observed when dental specimens were immersed in the Listerine products (LC and LM) for more than 90 minutes, but the degree of mineral loss for Listerine products was not statistically significantly different from that for groups without mineral loss. In conclusion, all five commercially available mouthwashes showed no harmful effects on tooth enamel.

Elderly Welfare System and Role of Dental Hygienists in Korea and Japan / 치위생과학회지

In accordance with the aged society, oral health care for the elderly is considered important to maintain general health. Although the role of dental hygienists is essential for proper health management of the oral cavity, research on the care system for the elderly people's oral health and on the role of dental hygienists in the field of elderly welfare is still insufficient. Hence, the aim of this study is to investigate the status of Korean elderly welfare system and dental hygienists by comparing them with those in Japan, a precedent of aged society. First, we compared and investigated the Japanese long-term insurance system, which provides an institutional basis for a long-term care system for the elderly in Korea. Second, the elderly welfare law and care system, focusing on oral care, were examined. Lastly, in elderly care, we analyzed the distinctions between Korea and Japan regarding dental hygienists' role and scope of work. Taken together, as a precedent of aged society, Japan has shown well-specialized and systematic welfare for the elderly compared with Korea. With the development of the welfare system for the elderly in Japan, the role and the workscope of dental hygienists have been expanded to improve quality of life of elderly people, as a key professional for elderly oral care. Therefore, we should perceive the need for improvement of long-term care insurance and the expansion of dental hygienists' work in Korea. In conclusion, these results could be used as basic data for improving the elderly welfare system and developing dental hygienists in Korea.

The Opinions of Some Dental Hygienists about Improvement of Korean Dental Hygiene Education / 치위생과학회지

This study's aim was to investigate their opinions to improve the educational system for dental hygienists on the basis of their duties as dental hygienists. The qualitative study was conducted among 19 dental hygienists at Daejeon, Korea from July to August 2016. Two researchers followed each subject for working hours in a day and recorded all the tasks and time to take for each task. After one day, the researchers met each subject and conducted face-to-face interviews to investigate the opinions about the dental hygiene curriculum and national board examination. The main duties recognized by more than half of the subjects were oral disease prevention including scaling and dental treatment assistance. The subjects' minority opinion about the main duties included radiography, impression taking, dental implant surgery assistance, orthodontic treatment, patient counseling, dental management and staff management, and oral health education. The most important tasks perceived by the subjects were prosthetic and implant impressions, scaling and implant surgery assistance. The subjects' minority opinion about the most important duties included patient counseling and making temporary crowns. The most difficult tasks answered by the subjects were prosthetic and implant impressions and dental implant surgery assistance. The subjects' minority opinion about it included patient counseling, scaling, and making temporary crowns. They mentioned that their curriculum in college was different from the actual work and the national board examination was not reflective of their real duties. We found out Korean dental hygienists had a lot of roles as dental assistants, dental business managers, and so on. We suggest that the law, curriculum and national board examination for dental hygienists should be revised to be able to reflect the reality of the clinical field.

Qualitative Research on Communication Education of Dental Hygienist by Focus Group Interview / 치위생과학회지

The purpose of this study to review clinicians and educators on required communication education factors of dental hygienists using qualitative research by focus group interview. The participants were dentists, dental hygienists and professors. A questionnaire was developed on communication education to collect data. The collated data derived concepts related to communication education. After transferring the data, were analyzed by open coding and axial coding using computer-aided qualitative data analysis software. Focus group emphasized that higher education on communication should be preceded before they are put into the clinical field. However, the dental hygienist emphasized experiential education in the clinical field, the professor emphasized additional education for continuity of communication education even after graduation. Besides, focus group emphasized role play, and the professor required that the standardization of the dental communication training courses objectives and role play modules and the education environment infrastructure should be established to implement communication education efficiently. The categories of communication education stated in the focus group were time and method for the dental communication training courses, dental communication training courses standardization and educational environment, of evaluation of communication competency, of perception of the dental communication training courses. This study identified the communication education development to conform with the needs of the clinical field strengthen and cultivate communication competency dental hygienists based on factors of communication education emphasized in focus groups.

Problems to Solve and Job Enlargement on the Inclusion of Dental Hygienists in the Category of Medical Personnel / 치위생과학회지

The purpose of this study was to examine the perceptions, precedent tasks, positive and negative effects, and expandable professional tasks regarding the inclusion of dental hygienists (DHs) in the category of medical personnel. This study involved a survey of 259 DHs and 128 dentists. The findings were as follows: 94.2% of DHs and 46.9% of dentists were aware of inclusion in the category of medical personnel; 95.0% of DHs and 64.1% of dentists supported the idea; and 84.9% of DHs and 51.6% of dentists recognized its legitimacy. As for precedent tasks for inclusion in the category of medical personnel, both DHs and dentists scored high points in professional consciousness in the area of occupation. Both DHs and dentists scored the highest points in the quality management of DH education and the lowest points in the unification of school systems in the area of institution. In the area of society, DHs scored high points in the persuasion of the central government, whereas dentists scored high points in collaboration among concerned organizations. Regarding the positive effects of inclusion in the category of medical personnel, both DHs and dentists scored the highest points in the expanded perception of DHs. As for its negative effects, DHs scored high points in the aggravation of salary increase, whereas dentists scored high points in the aggravation of salary increase. Regarding expandable professional tasks after the inclusion of DHs in the category of medical personnel, the management of independent periodontal care programs recorded the highest percentage both in DHs and dentists. These findings highlight the need for adequate discussions about the meanings of the inclusion of DHs in the category of medical personnel and will hopefully contribute to the rational adjustment and legalization of DHs' works with regard to their inclusion in the category of medical personnel.

Clinical Competency of Dental Hygiene Students to Manage Disabled Patients in Some Areas / 치위생과학회지

The demand for medical care and welfare for patients with disabilities is expanding, and healthcare professionals are also increasingly interested in the need for medical care for patients with disabilities. The purpose of this study was to evaluate the competency of disabled patients' management and the education experience of dental hygiene students, who are the main players of oral health care for disabled patients. A total of 196 students in the dental hygiene department and 3rd and 4th grade students were surveyed using questionnaires. As a result, most of the students had a positive awareness of disabled patients; 84.7% answered with the need to train dental hygienists in specializing in handicapped patients, 76.5% were willing to attend seminars related to disabled patients after graduation, and 71.4% of the students provided dental treatment for patients with disabilities in curriculum and comparative curriculum. The students who provided treatment for disabled patients showed that their competence in most areas of knowledge of disabled patients, oral health education, and oral disease prevention was highly evaluated as significant. The competence of respondents who answered that the theoretical education was sufficient was significantly higher. Based on this, institutional support for the education of dentistry for disabled patients is needed, and sufficient theoretical education and practical training should be offered to foster personnel capable of contributing to the improvement in the oral health of patients with disabilities. In addition, in-depth discussions on the training of dental hygienists specialized in handicapped patients should be conducted.

Evaluation of Dental Hygienist Job Validity according to Judgment Standard of Medical Practice in Medical Law / 치위생과학회지

The purpose of this study was to evaluate the validity of dental hygienist job according to judgment standard of medical practice in medical law. In this study, we conducted a self-administered questionnaire survey to evaluate the validity of dental hygienist job for 12 professors of dental college in Gangneung-Wonju National University from November 10 to 20, 2017. We investigated whether the dental hygienist job conforms to the three criteria of medical practice such as disease prevention and treatment, patient care, and health hazard. The response rates were scored and classified into four categories according to the final score. As a result of this study, dental hygienist job are classified into four categories according to judgment standard of medical practice. The higher the level of the category, the higher the degree of difficulty, and the higher the level of expertise and skills required. More than 50% of respondents answered that measuring the gingival pocket, bleeding on probing, professional tooth cleaning, oral health education, counseling after dental treatment are all three criteria for medical treatment. And these were classified into Level 4 group which requires the difficulty and expertise in the final score 4.3. It is necessary to develop and utilize standardized guidelines on the level of knowledge, education, and qualification standards required for dental practice in order to effectively allocate work among the dental personnel while ensuring the health rights of patients in the dental clinic field in Korea. In addition, there is a need to evaluate the various aspects of cost effectiveness, dental health service productivity, and health promotion contribution to dental hygienist jobs, And based on this evidence, it is necessary to continue to expand and adjust the dental hygienist job and to reorganize the dental workforce system.

Factors Affecting Job Satisfaction of Clinical Dental Hygienists / 치위생과학회지

This study attempted to identify factors work environment that affect job satisfaction in dental hygienists. This study was conducted between August 29 and September 28, 2017, as part of an in-depth study of the ‘Survey on the Working Environment of Clinical Dental Hygienists’ of the Korean Dental Hygienists Association. To get the responses, the questionnaire was posted on the website of the Korean Dental Hygienists Association, and of the respondents, 4,663 were selected and analyzed. An independent t-test and one way ANOVA analysis were used to make a comparison of job satisfaction according to the general characteristics, salary, and tasks. Logistic regression analysis was conducted to identify factors affecting job satisfaction. The significance level was 0.05. In regard to salary information, the job satisfaction was found to be high (p < 0.001) in cases where the salary was considered appropriate, when incentives were provided, when rewards or vacation expenses were supported, and when overtime and nightly work allowances were paid. In regard to job information, the job satisfaction was found to be high (p < 0.001) when the volume of work was considered appropriate, when there were sufficient numbers in the workforce, and when the division of labor among the other personnel was clear. As a factor affecting job satisfaction of dental hygienists, the case of thinking that ‘workload is appropriate’ was found to be 2.052 times, showing the highest score. Job satisfaction in dental hygienists affects the turnover and has a significant effect on the performance of the organization. Therefore, it is believed, that it is urgent to improve the working environment such as salary and clear division of duties affecting job satisfaction of dental hygienists.

Relationships between Experiencing Verbal Violence and the Emotional Responses and Coping Behaviors of Dental Hygienists / 치위생과학회지

This study investigated the relationships between experiencing verbal violence and the emotional responses and coping behaviors of dental hygienists who worked in Jeonju between February 24 and March 18, 2017 to prepare strategies for managing verbal violence and establish a healthy working environment for dental hygienists. The following findings were obtained in this study. The dental hygienists primarily experienced verbal violence from patients and guardians (1.67 points). The most common verbal violence type was, “Someone treated me impolitely.” The most common emotional response to verbal violence was “anger” (3.52 points). The coping style of most dental hygienists was problem-focused coping (3.28 points), followed by emotion-focused coping (2.75 points). Most hygienists with the problem-focused coping style stated that they resolve the problem through dialogue (3.51 points), while most hygienists with the emotion-focused coping style responded that they just ignore the situation (3.78 points). The relationship between experiencing verbal violence and the emotional responses and coping behaviors of dental hygienists showed a statistically significant positive correlation (p<0.05) with emotional responses and problem- and emotion-focused coping associated with experiencing verbal violence from dentists, patients, and guardians. These findings confirm the need to reduce verbal violence, control emotional responses after exposure to verbal violence, and use more problem-focused coping measures. Dental hygienists must develop interpersonal skills and communication techniques and promote professionalism in their workplace to protect themselves from verbal violence at work.

Effects of Infection Control Training on Dental Hygienists' Health Beliefs and Practices of Infection Control / 치위생과학회지

This study aims to determine the changes in health beliefs and practices of dental hygienists on infection control after having received special training on that subject. The study population consisted of dental hygienists working at the dental institutions located in Seoul and Gyeonggi areas. The intervention group and the control group each had randomly assigned 26 dental hygienists. The intervention group received training courses on infection control once a week for 3 hours, for a total of 4 training sessions. We used a survey tool to find the changes between the two groups regarding their health beliefs and practices on infection control measures. The survey was conducted prior to the training sessions, 3 months and 2 weeks after the training. The study results revealed statistically significant increases in perceived sensitivity, perceived seriousness, and perceived benefits after the training courses in the intervention group (p<0.05). A statistically significant decrease in perceived barriers was also noted in the intervention group (p<0.05). Additionally, there was a statistically significant increase in the practice of infection control in the intervention group as compared to the control group (p<0.05). Therefore, we conclude that infection control training is crucial in bringing about positive changes to the health beliefs of dental hygienists, and a structured system is necessary for continuous infection management along with training in order to improve infection control practices.

Relationship between Happiness and Job Satisfaction of Dental Hygienists / 치위생과학회지

This study was conducted to provide basic data on the relationship between the happiness and job satisfaction of dental hygienists. The research subjects were 264 dental hygienists in Busan and Gyeongsangnam-do. The study was conducted using structured questionnaires and the collected data were analyzed using IBM SPSS software, ver. 20.0. The happiness index, which was based on general characteristics, showed the greatest significant differences in life satisfaction (p<0.05) among adults over 36 years of job experience, negative emotions (p<0.01) among adults under 25 years of job experience, and negative emotions (p<0.05) among adults with 4~10 years of job experience. The factors that improved the job satisfaction of dental hygienists were life satisfaction, prime duty at the work place, and a positive effect. On the contrary, negative emotions lowered the job satisfaction. The happiness of the dental hygienist is an important factor not only for the improvement of the hygienist's personal quality of life, but also the patient's health. It is necessary for dental hygienists to maintain good relationships with coworkers during in the workplace, as well as employers, to have an administrative system that offers proper compensation, improvement of the work environment, and opportunities to improve professionalism at the workplace.

The Effects of Critical Thinking Disposition and Problem Solving Ability on the Work Performance Assessment of Dental Hygienists / 치위생과학회지

The purpose of this study was to improve work performance conducted at an actual clinical site by determining the relationship among critical thinking disposition, problem solving ability, and work performance. In this study, 335 dental hygienists completed self-administered survey. Final analysis was conducted with a total of 331 responses, excluding 4 questionnaire with unreliable responses and non-responses. The results indicated that as the age, educational background, and work experience of the subjects increased, their critical thinking disposition and problem solving ability scores increased and were statistically significant. For work performance, average total score was high for age, educational background and work experience, but only age and work experience were statistically significant. Critical thinking disposition, problem solving ability and work performance of the subject were relevant, and all of them were significant. Work performance was also influenced indirectly by mediating problem solving ability in critical thinking disposition. In other words, both direct and indirect effects were significant, and the existence of partial moderating effect was verified. Thus, in order to improve work performance of dental hygienists, a multilevel educational process that can simultaneously improve critical thinking disposition and problem solving ability of dental hygienists needs to be developed. Therefore, it is expected that the new dental hygiene company will be able to perform without any sense of disparity in the clinical field; this will solve the gap between dental hygiene education and practical skills.

The Effect of Violent Experience on Burnout among Some Dental Hygienists / 치위생과학회지

This study investigated the effect of violent experience on burnout among some dental hygienists. The study subjects were 242 dental hygienists working at dental clinics. Data were collected by self-administered questionnaire including information such as demographics, work-related characteristics, working environment, experience of violence, and burnout. The violence was classified as verbal violence, physical threat, or physical violence committed by dentists, patients, or caregivers. Descriptive analysis, t-test, ANOVA, correlation, and multiple linear regression analysis were performed to examine the factors associated with burnout. The levels of verbal violence, physical threat, and physical violence by dentists were 0.53±1.26, 1.12±2.70, and 0.04±0.42, respectively. The levels of verbal violence, physical threat, and physical violence by patients and caregivers were 1.50±1.89, 1.41±2.24, and 0.24±1.38, respectively. The score of burnout was 3.13±0.43. Total violence, verbal violence, and physical violence by dentists were positively correlated with burnout. Total violence, verbal violence, and physical threat by patients and caregivers were positively correlated with burnout. In multiple linear regression analysis, the level of physical violence by dentists was positively associated with burnout of dental hygienists (β=0.95, p=0.032). The levels of total physical violence (β=0.28, p=0.002), verbal violence (β=0.15, p<0.001), and physical threat (β=0.19, p=0.009) by the patients or caregivers were positively associated with burnout of dental hygienists. This study examined the association between violence and burnout among dental hygienists. The level of violence showed positive correlation with burnout. Environment improvement to protect employees from violence and for management of employees who experienced workplace violence are needed to reduce the burnout.
