Accidental implantation of a bur tip in the elbow of a dentist. A possible pathway for inoculation with deadly infectious agent

RESUMO

The most common source of occupational injury to dentists is percutaneous puncture of the hands from "sharps". We report a percutaneous injury involving a dentist where the tip of a dental bur became implanted in his elbow. The dentist had been vaccinated against Hepatitis B and both the patient and dentist were Hiv and Hepatitis B seronegative immediately after the incident. Surgical exploration of the dentist's elbow the following day was unsuccessful in locating the bur tip. The dentist remains healthy and is not incapacitated as a result of the injury, despite retention of the bur tip. This accident has implications for modifying the design of present and future dental units. We are not aware of a previous report of this type of injury.
