The American Dental Association (ADA), a professional organization that provides resources such as education and legislative advocacy, maintains an active role in supporting and conducting research in the field of dental science. A member of the ADA and owner of his own practice in Staten Island, New York, David J. Flynn, DDS, supports the many programs being conducted by the association and offers this brief overview of some of the current research being funded by the ADA Foundation Research Institute.
Microbial Numbers in Dental Unit Water Lines
In spite of a 1995 ADA recommendation that dental equipment manufacturers limit the quantity of bacteria in dental unit water lines to 200 CFU/mL, some lines may contain bacteria levels of more than 50,000 CFU/mL. Although researchers have not identified high CFU levels as a cause of illness in patients, it may nevertheless pose a health risk to those with compromised immune systems. Researchers at the ADA survey manufacturers and ensure compliance with ADA recommendations regarding CFU readings.
Sterilization of Dental Handpieces
To reduce the risk of cross contamination among patients via blood and saliva on dental instruments, the ADA highly recommends steam sterilization, which eliminates infectious agents and significantly reduces the risk of transmission. However, the effectiveness of steam sterilization may vary extensively based on the type of equipment involved in the process. Through its research, the ADA assesses the quality of several methods of steam sterilization, particularly on handpiece turbines.
Aerosol Research Project
In recent years, many members of the scientific community have voiced their concern over the potential of aerosols and solid particulate matter to transmit infections. Through its research project, the ADA uses tools in a simulated dental environment to evaluate the health risks posed by bio-aerosols. The ADA then uses the data generated by the study to develop guidelines in conjunction with the American Society of Heating, Refrigerating, and Air-Conditioning Engineers, Inc.
