Area of Science:

  • Dental Materials Science
  • Nanotechnology
  • Occupational Health

Background:

  • Nanoparticles (1-100nm) are naturally occurring and widely used in daily products and dental materials.
  • Concerns exist regarding potential adverse effects of nanoparticles, particularly on the lungs.

Purpose of the Study:

  • To evaluate potential nanoparticle exposure risks in dental settings.
  • To assess the risks associated with nanoparticles in dental materials and procedures.

Main Methods:

  • Analysis of nanoparticle exposure during dental laboratory work, material processing, and intraoral adjustments.
  • Review of existing regulations for dental technicians.
  • Worst-case mass-based exposure calculations for dental personnel and patients.

Main Results:

  • Exposure to nanoparticles in dental labs can occur during material processing.
  • Intraoral grinding/polishing and wear of dental materials generate nanoparticles.
  • Calculated exposure risks for dental personnel and patients are low to negligible.

Conclusions:

  • Current dental materials pose a low additional risk from nanoparticles.
  • Measures like water coolants and ventilation can reduce exposure.
  • More research is required on nanoparticle risks, especially for vulnerable groups and the environment.
