Dental professionals face ongoing risks of infection transmission, including human immunodeficiency virus (HIV) and hepatitis C virus (HCV). Inconsistent infection control practices and sharps injuries highlight the need for improved safety measures in dental settings.

Area of Science:

  • Infection Control
  • Dental Public Health
  • Occupational Safety

Background:

  • The dental workplace presents a low but persistent risk of infection transmission.
  • Recent data indicate potential human immunodeficiency virus (HIV) transmission between dentists and patients.
  • Staff remain at risk for hepatitis C virus (HCV) and varicella zoster virus infections during dental procedures.

Purpose of the Study:

  • To review current shortcomings in cross-infection control within dental settings.
  • To highlight persistent risks despite advancements in infection prevention.
  • To identify areas requiring improved protocols for dental healthcare workers.

Main Methods:

  • Review of recent data on nosocomial infections in dentistry.
  • Analysis of current cross-infection control practices and their effectiveness.

  • Examination of challenges in preventing occupational exposure to bloodborne pathogens.

    • Main Results:

    • Inconsistent sterilization methods and inadequate protective clothing for ancillary staff noted.
    • Clinician reluctance to treat patients with hepatitis B virus (HBV) or HIV infection persists.
    • Reusable gloves are unsafe due to micropunctures; sharps injuries remain a significant risk for HIV and HCV exposure.
    • Contaminated dental unit water supplies and unverified disinfection of impressions pose ongoing challenges.

    Conclusions:

    • Despite low overall risk, significant gaps in cross-infection control persist in dental workplaces.
    • Enhanced protocols are needed for sterilization, protective equipment, and managing sharps injuries.
    • Further research is required to ensure the inactivation of infectious agents on dental impressions and in waterlines.
