Occupational hazards in dentistry – Knowledge attitudes and practices of dental practitioners in Belgaum city

Awareness of occupational health hazards and occupational stress among dental care professionals: Evidence from the GCC region

A hazardous work environment creates critical concerns, and resultantly, workers may suffer from job-related stress. So, this study aimed at identifying the nature of hazards prevailing in dental hospitals and their role in increasing job-related stress. The study also assumes that awareness of the existence of health hazards and their possible risk will originate the stress. To conduct the study, close-ended questionnaires were administered to 300 workers having more than 1 year of experience in Oral and Dental Health Services provided by the Kingdom of Bahrain. In total, 222 responses with an acceptable level of accuracy were included for statistical treatment. Results confirmed the prevalence of ergonomic, biological, physical, and, to some extent, chemical hazards in the workplace. Results revealed that stress befalls the employees as they know their exposure to these hazards. Ergonomic hazards have the highest prevalence, chemical hazards are the least prevalent, while biological and physical hazards fall in between. This study enriches the related bank of literature by tapping the hazards specifically in the dental hospitals' environment with the degree of intensity of their prevalence within the context at hand. The study of the impact of these workplace health hazards on occupational stress with mediating effect of awareness is also an addition to the existing literature. The findings may help hospital administrators to take correct measures to manage job-related stress that is counterproductive and take remedial steps to mitigate these hazards.

Safe use of chemicals and risk communication among dentists and dental students in Greece

Use of chemicals, most often classified for intrinsic hazards, is rather common among dentists. To date, no data have been recorded in the European Union (EU) on dentists' awareness regarding the safe use of chemicals. In the EU regulatory framework, two Regulations with wide applications, namely Regulations (EC) 1907/2006 (REACH) and 1272/2008 (CLP), have been introduced to protect human health and the environment and clearly communicate hazards posed by chemicals to workers and consumers. The aim of this study was to assess the extent of comprehension of hazard communication of chemicals among Greek dentists. For this, a closed-ended, anonymous and validated questionnaire was initially distributed to a total of 300 Greek dentists, both professionals and university students, over a period of 4 months. The collected data from 240 final responders were subjected to statistical analysis (frequencies, percentages, chi-square (χ²) and significance (p < 0.05)). The vast majority (90%) of the interviewed dentists are not aware of the CLP. Main sources of information regarding chemical hazard and safe use was the supplier through direct communication (90%), while some dentists also consulted the product labels (39%) and the material safety data sheets (54%). Regarding hazard communication, the perceived information from the pictograms is confusing to the vast majority of the dentists (86%), especially for systemic hazards (carcinogenicity and/or reproductive toxicity). In addition, 88% of the professional dentists have not noticed any changes in the labelling of chemical products, which also shows the low input of labels to hazard communication. On the other hand, 90% of the responders always utilize personal protective equipment (PPE), although it is not clear whether this PPE is adequate. In conclusion, rising awareness campaigns are needed, in collaboration with universities and dental care professional associations, to inform dentists about the safe use of chemicals not only to ensure protection of their own health but also to contribute to environmental sustainability.

Knowledge, attitudes and perceptions of occupational hazards and safety practices in Nigerian healthcare workers

Background

By profession, healthcare workers (HCWs) attend to clients and patients through a variety of preventive and curative services. However, while their attention is focused on providing care, they are vulnerable to hazards that could be detrimental to their health and well-being. This is especially true in developing countries where health service delivery is fraught with minimal protective precautions against exposures to numerous fomites and infectious agents. This study assessed the workplace hazards and safety practices by selected HCWs in a typical health care facility (HCF) in Nigeria.

Methods

The study utilized a descriptive cross-sectional design and stratified sampling technique to identify 290 respondents. The study used mixed methodology and collected data by validated instruments with resulting data analyzed by IBM-SPSS, version 20.

Results

The results showed that over half of the respondents were registered nurses, female, married (61.7 %) with 5 years median work experience (70.3 %). Most respondents (89 %) were knowledgeable about hazards in HCFs, identified recapping used needles as a risky practice (70 %) and recognized that effective hand washing prior to, and after every clinical procedure in preventing cross infection (100 %). Also, most respondents (96.2 %) believed they were at risk of occupational hazards while about two-thirds perceived the risk as high. In addition, only 64.2 and 87.2 % had completed Hepatitis B and Tetanus immunizations, respectively. Only 52.1 % “always” complied with standard procedures and most (93.8 %) practice safe disposal of sharps (93.8 %) while those that did not (40 %) generally implicated lack of basic safety equipment. In this study, the practice of hand washing by respondents was not influenced by occupation and education.

Conclusions

The high level of knowledge demonstrated by respondents was at variance with practice, therefore, measures aimed at promoting safety practices and, minimizing exposure to hazards such as; provision of safety equipment, pre-placement and routine training of staff on safety practices and adequate reinforcement of staff capacity and capability through drills in all HCFs should be institutionalized and made mandatory. The protocol of the safety training and drills should be responsive to evidence-based emerging and sectoral safety challenges.
