Area of Science:

  • Dentistry
  • Occupational Health
  • Infectious Disease Prevention

Background:

  • Percutaneous injuries pose a significant risk to dental professionals.
  • Understanding the frequency and nature of these injuries is crucial for prevention strategies.

Purpose of the Study:

  • To investigate the current incidence and causes of percutaneous injuries among practicing U.S. dentists.
  • To compare current injury rates with historical data.

Main Methods:

  • A novel diary study involving 2,304 practicing U.S. dentists.
  • Data collected over a one dentist-month period.
  • Analysis of injury types (extraoral vs. intraoral) and causative agents.

Main Results:

  • Burs were the leading cause of extraoral injuries (40%).
  • Syringe needles were the primary cause of intraoral injuries (32%).
  • The annualized mean injury rate was 3.35 per dentist, a threefold decrease since 1987.

    • Conclusions:

    • Percutaneous injury rates among dentists have substantially declined.
    • Targeted prevention efforts should address burs for extraoral and needles for intraoral injuries.
    • Continued surveillance is necessary to maintain and further reduce injury rates.
