Abstract

Abstract: Objective: Focusing dentists and dental hygienists employed in the Public Dental Health Services (PDHSs) in Norway, this study set out to assess whether socio-demographic factors, familiarity with nanotechnology and social trust are associated with dental health care workers' perceived risks and benefits of use of nanomaterials in dentistry and whether those associations varied according to professional status. It was hypothesized that increased knowledge, trust in stakeholders and familiarity with nanomaterials would decrease the risk and increase benefit perceptions among dental health care workers. Methods: Electronic questionnaires were administered to a census of 1792 dentists and dental hygienists. Results: About 64% and 69% of respondents perceived respectively, risk and benefits associated with use of nanomaterials. Multiple variable logistic regression revealed that dentists were more likely than hygienists to perceive risks (OR = 1.9, 95% CI 1.1–3.3) and benefits (OR = 3.6, 95% CI 2.1–6.2). Having experience with dental nanomaterials (OR = 2.2, 95% CI 1.3–3.7) and feeling safe (OR = 6.6, 95% CI 3.1–14.2) increased perceived benefits. Having moderate or much correct knowledge about nanotechnology (OR = 2.3, 95% CI 1.5–3.5) increased the likelihood of perceived risk. Conclusions: Policy makers should consider the factors that influence dental health care workers' risk and benefit perceptions associated with the use of nanomaterials in dentistry.
