Contamination of the turbine air chamber: a risk of cross infection

. In the present work, we evaluated (a) the influx of contaminating fluid into the air chamber when a high‐speed turbine stops rotating, (b) the significance of a series of variables (type of handpiece and dental unit, shape of the bur, number of stops set on the turbine) which condition it, and (c)...

Description
Summary:. In the present work, we evaluated (a) the influx of contaminating fluid into the air chamber when a high‐speed turbine stops rotating, (b) the significance of a series of variables (type of handpiece and dental unit, shape of the bur, number of stops set on the turbine) which condition it, and (c) the time required to expell the contaminating fluid from the turbine head. Results showed that contamination takes place every time the turbine stops rotating with the bur in contact with an external fluid. The main variable affecting the influx of contaminating fluid into the air chamber of the turbine head was represented by the shape of the bur (F=54.9; p
