title: The efficiency of nitrous oxide scavenging devices in dental offices.
abstract: Five scavenging systems were installed in 10 dental office and the levels of nitrous oxide were closely monitored for each. While the readings were higher than the previous non-clinical study, all appeared to be reasonably efficient. The various factors which caused increases in background levels were also recorded in the investigation.
