Contamination of dental unit cooling water with oral microorganisms and its prevention
Bagga BS, Murphy RA, Anderson AW, Punwani I.
J Am Dent Assoc. 1984;109(5):712-716.
DOI: 10.14219/jada.archive.1984.0168
Abstract
The retraction valve of modern dental units was studied to determine whether bacteria are aspirated into the water line and whether this could be prevented with a check valve. Retraction valves on modern dental units may cause cooling water to return to the unit...
Control of cross-infection risks in the dental operatory: prevention of water retraction by bur cooling spray systems
Crawford JJ, Broderius C.
J Am Dent Assoc. 1988;116(6):685-687.
DOI: 10.14219/jada.archive.1988.0014
Abstract
A new dental unit control system was found to overcome the possibility of mechanically retracting bacteria from the mouth into the water line used to provide a spray of water to cool high-speed burs during treatments. This was demonstrated by results obtained after clinical use in simulated, worst case test conditions using a red tempera indicator solution and indicator bacteria...
Prevention of infection in dental procedures
M Matsuyama, T Usami, K Masuda, N Niimi, M Ohta, M Ueda
J Hosp Infect. 1997;35(1):17-25.
DOI: 10.1016/s0195-6701(97)90164-x
Abstract
The efficacy of a newly-developed anti-cross-contamination device in dentistry, the Air Flushing Clean System (AFCS), was tested under experimental and clinical conditions. In the experimental situation, a dental air turbine handpiece with or without AFCS was contaminated with two bacterial strains, Staphylococcus aureus FDA209P and Streptococcus mutants ATCC25175...
