Sharps injuries in dental practice.

Sharps injuries are common in dental practice and may allow transmission of blood-borne viruses. The transmission rates of hepatitis B (HBV) to non-vaccinated recipients, hepatitis C (HCV) and human immunodeficiency virus (HIV) after a needlestick injury are 6-30%, 2.7-10% and 0.1-0.3% respectively. Five strategies to prevent percutaneous injuries in dental surgeries are considered: a universal level of infection-control, surgery design, working practices, glove use and vaccinations. First-aid for sharps injuries and post-exposure management of those involving sources with HBV and HIV are described. Anticipation, planning and training can reduce the incidence of injuries and minimise their impact.
