The article discusses an in vivo study which examines whether air-driven low-speed handpiece motors can become contaminated with oral flora when used with prophylaxis angles. The researchers used each handpiece/prophylaxis angle system to polish teeth. The study suggests that the internal surfaces of low-speed handpieces can become contaminated with bacteria when used with prophylaxis angles.
