Prevention of Infection of Compressed Air by Bacteria-screening

Abstract

Dental turbines operated by compressed air have been used not only in treatment of teeth such as in excavation, tooth support formation teech, or extraction of the dental pulp but also in operations such as difficult cases of tooth extraction, alveolar bone formation, root amputation, and bone marrow implantation.
While sterile water is used in operations, the compressed air with which turbines are operated can be contaminated with dust and bacteria and it is considered that the measures to make the air should be used especially while conducting bone marrow implantation.
Domnik-Hunter is a filter developed in England and has been used in air cleaners for polluted air and as air filters in factories. Recently filters with compressed air for dental use has been developed and proved to be very effective.
Thus, we report examined turbine hoses with and without connection to Domnik-Hunter from a bacteriological viewpoint.
