The mechanisms of nitrous oxide scavenging devices

A recent publication discussing the concern with nitrous oxide pollution in dental offices and the methods available to reduce this risk aroused interest in scavenging systems. This is the first in a series of three articles and will explain the mechanisms of the nitrous oxide systems available. The second describes the testing of these systems under ideal conditions and the third will assess their efficiency in various dental offices and the factors which were found to detract from that efficiency.
