Background: Work of a dental technician is associated with exposure to a number of harmful factors. We can distinguish: chemical, biological, physical and psychophysical factors. They contribute to many diseases, but not all of them are classified as occupational diseases. The main aim of the study was to assess the health hazards that occur in the workplace of a dental technician and their prevention during the COVID-19 pandemic.

Material and methods: An epidemiological cross-sectional study was conducted. A self-created questionnaire form containing 28 questions was used. The link to the survey was shared on social groups associating dental technicians. Participation in the study did not require logging in. During the data collection, the respondents' personal data were not collected and processed.

Results: 148 dental technicians participated in the study. The largest group were participants aged 21-25 (32%), the smallest group were people over 50 (6%). The most frequently occupied position was acrylic and plaster. More than 1/3 of those surveyed reported having allergies, most often to acrylic or metal. More than 20% of technicians reported experience of mechanical injuries several times a week or more. 17% of technicians declared professional burnout. 80% of technicians used protective clothing. Personal protective equipment was always used by only 22% of technicians, and as many as 29% of respondents never used the listed protective equipment.

Conclusions: Not all dental laboratories were equipped with the necessary personal protective equipment. The most commonly used personal protective equipment included: disposable gloves, disinfectant liquid and extract. The COVID-19 pandemic contributed to a change in disinfection procedures in more than 1/3 of the respondents. 35% of them started using disinfection only after the outbreak of the pandemic, while most of the changes concerned the improvement of existing procedures. The length of work experience of technicians had an impact on exposure to stress and occupational burnout. Med Pr Work Health Saf. 2023;74(4):289-99.

This paper summarizes the currently available knowledge on the impact of infrasound and low frequency noise (LFN) on human health and well-being. This narrative review of the literature data was based on the selected, mostly, peer-reviewed research papers, review articles, and meta-analyses that were published in 1973-2022. It has been focused on infrasound perception, annoyance attributed to infrasound and low-frequency noise, as well as their effects on the cardiovascular system and sleep disorders. Particular attention was also paid to the latest research results and specific sources of infrasound and LFN, i.e., wind turbines. Med Pr Work Health Saf. 2023;74(4):317-32.

Background: Job satisfaction is one of the key factors related to the work efficiency of nursing staff. Its level may affect the degree of the professional's commitment to work and effectiveness in performing their professional tasks. For a modern organisation, job satisfaction is associated with a number of benefits for both the employee and the employer. Job satisfaction of nurses is extremely important due to their professional tasks being related to the care of patients. Nurses with low levels of job satisfaction may have less capabilities to provide high quality care and thus maintain a high level of patient satisfaction.

Material and methods: This was a cross-sectional observational study which included 302 people practising the profession of a nurse and employed in a hospital during the COVID-19 pandemic. The level of job satisfaction was assessed using the Minnesota Satisfaction Questionnaire (MSQ), which was preceded by questions characterising the research group. The questionnaire was delivered to the respondents in electronic form.

Results: The respondents obtained an average result in terms of the level of job satisfaction (M±SD 58.53±11.42). The highest rated area was the chance to do something good for other people (M±SD 3.85±0.87), and the lowest rated areas included: the method of work evaluation and the remuneration system (M±SD 2.24±0.74), the chances for advancement (M±SD 2.38±0.94) and the chance to take up senior positions (M±SD 2.39±0.88) as well as the number of tasks to be performed during the working day (M±SD 2.40±0.86).

Conclusions: In this study, average values of the level of job satisfaction were obtained. A higher level of job satisfaction was shown by those employed in a non-infectious hospital and those with higher monthly earnings. Employers' policy should focus on improving working conditions, the remuneration system and promotion opportunities. Med Pr Work Health Saf. 2023;74(4):271-8.
