 AB    OBJECTIVE: Oral surgeons use high-speed handipieces for various invasive
       dental procedures to HIV infected patients. This study investigated the
       incidence and extent of blood contamination of handpieces used in
       invasive dental procedures. METHODS: Water samples were collected from
       high-speed handpieces used for the extraction of the lower third molar
       in thirty non-infected adult patients. We employed an occult blood test
       stick for saliva in order to detect blood contamination of samples.
       Various risk factors for handpiece contamination were analyzed by chi 2
       test. RESULTS: The extraction of low positioned horizontally impacted
       wisdom teeth and water retension in operated wounds at a stop moment of
       handpieces were statistically significance as risk factors. DISCUSSION
       AND CONCLUSIONS: As a countermeasure of blood contamination of
       handpieces, burrs should be kept apart from retension water in deep
       operated wounds at a stop moment. The use of an anti cross-contamination
       device is also indicated.
