Objectives: The purpose of this study was to examine the differences of dental hygienists in how they view their work and how they rate their emotional labor and occupational stress. Gathering this data was an effort to provide information on how to increase occupational satisfaction and improve work environments for dental hygienists. Methods: We analyzed data collected from 178 dental hygienists. The dental hygienists were randomly selected by convenience sampling from dental hospitals. Results: Our results showed that pediatric hygienists had more negative responses in regard to their views on their work. As for emotional labor, dental hygienists from pediatric dental clinics experienced heavier emotional labor than those from general dental clinics. On the other hand, dental hygienists from general dental clinics suffered more from occupational stress than pediatric dental hygienists did. Conclusions: Given the findings of this study, effective and ideal programs that promote occupational satisfaction for dental hygienists should be prepared, and strategies should be developed to resolve emotional labor and improve their work environments, as well.

Objective: The objective of this study was to evaluate the prevalence and incidence of accidents with biological material, the level of knowledge, and compliance to standard precautions (SPs) among dentists, physicians, nurses, and dental and medical students. Methods: A closed cohort study with a prospective and retrospective component was conducted between August 2014 and September 2015. The participants were contacted in two moments during the follow-up period, during which a structured questionnaire divided into six sections was used; the interviews were conducted during the follow-up period (Month 6) and at the end of the observation period (Month 12). Results: The global prevalence of accidents in the previous 12 months was 10.2%, with a difference between professionals and students (13.0% vs. 5.1%, respectively; p < 0.003). The incidence rate was 6.49 per 100 person/year, with difference between the groups (6.09 per 100 person/year in professionals and 7.26 per 100 person/year in students), type of specialization (hazard ratio, 3.27), and hours worked per week (hazard ratio, 2.27). The mean of compliance to SP was 31.99 (±3.85) points, with a median of 33 (30, 35) points against the expected 27.75 points. Adherence to SP was associated with the accident report (p < 0.020). Conclusion: We conclude that the proportion/incidence rate of accidents with biological material was high in relation to that in the literature, being higher in professionals and especially among physicians. The levels of knowledge and adherence to SP were good, with the best found in dentists and dental students.

Objectives: This cross-sectional study was performed in the Dental School of Prince of Songkla University to ascertain noise exposure of dentists, dental assistants, and laboratory technicians. A noise spectral analysis was taken to illustrate the spectra of dental devices. Methods: A noise evaluation was performed to measure the noise level at dental clinics and one dental laboratory from May to December 2010. Noise spectral data of dental devices were taken during dental practices at the dental services clinic and at the dental laboratory. A noise dosimeter was set following the Occupational Safety and Health Administration criteria and then attached to the subjects' collar to record personal noise dose exposure during working periods. Results: The peaks of the noise spectrum of dental instruments were at 1,000, 4,000, and 8,000 Hz which depended on the type of instrument. The differences in working areas and job positions had an influence on the level of noise exposure (p < 0.01). Noise measurement in the personal hearing zone found that the laboratory technicians were exposed to the highest impulsive noise levels (137.1 dBC). The dentists and dental assistants who worked at a pedodontic clinic had the highest percent noise dose (4.60 ${\pm}$ 3.59%). In the working areas, the 8-hour time-weighted average of noise levels ranged between 49.7-58.1 dBA while the noisiest working area was the dental laboratory. Conclusion: Dental personnel are exposed to noise intensities lower than occupational exposure limits. Therefore, these dental personnel may not experience a noise-induced hearing loss.

Purpose: The purpose of this study was to investigate occupational distribution of temporomandibular disorders (TMD) patients and their diagnosis according to occupations and to evaluate the relationship between TMD and occupations. Work-related factors which might aggravate TMD symptoms were also evaluated. Methods: We investigated 316 TMD patients, aged from 13 to 65 years old, who had visited the Department of Oral Medicine in Pusan National University Dental Hospital. The subjects who have a job were assessed using TMD analysis examination and occupation questionnaire. The level of significance was p-value<0.05. Result: This study presented that the diagnoses according to occupations were not significant, but work-related factors such as verbal work and poor posture were related with TMD symptoms. Conclusions: Proper education is essential to prevent aggravation of TMD symptoms because TMD symptoms were more related to work environment than a specific occupation.

Purpose: The purpose of this study is to clarify the mediating effect of the basic occupational ability in relation to the career barrier and job-seeking efficacy of dental technology students. It aims to provide the basic data for NCS-based education and career guidance. Methods: The subject of the questionnaire survey was dental technology students. The collected data were analyzed using the SPSS 21.0 program. For reliable verification, a significance level of ${\alpha}=.05$ was used and reliability analysis, frequency analysis, descriptive statistics analysis, correlation analysis and regression analysis were performed. Results: The results of the analysis showed that the basic occupational ability had a mediating effect in relation to career barriers and job-seeking efficacy. It was found that the basic occupational ability had a mediating effect in the relationship between job-seeking efficiently and other variables such as difficulty in an interpersonal relationship, lack of self-clarification, conflict with others in important positions, lack of job information, and lack of interest. Conclusion : The results of this study confirmed the importance of the basic occupational ability in improving job-seeking goals, job motivation, job search strength, job skills, and other related areas. If it appears difficult to overcome career barriers such as interpersonal difficulty, lack of self-clarification, conflict with other important people, lack of job information, and lack of interest, then the improvement of the basic occupational ability can be expected to enhance the job-seeking efficiency.
