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.
