We evaluated the risk of hepatitis B virus (HBV) transmission via dental handpieces and the effects of an anti-suction device in preventing HBV contamination. The results of our study show that under certain conditions, HBV transmission can occur when an anti-suction device is used during dental procedures. We conclude that such devices may decrease contamination, but do not eliminate it.
