National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Study Protocol: Control of Anesthetic Gases in Dental Operatories.

PB94218468

Publication Date	1988
Personal Author	McGlothlin, J. D.; Jensen, P. A.; Todd, W. F.; Fischbach, T. J.
Page Count	68
Abstract	An experimental design was developed to provide information which could be used to achieve airborne nitrous-oxide (10024972) (N2O) exposure for dental personnel of less than 25 parts per million as a time weighted average per dental procedure. The activities of various federal, professional and trade associations related to the dental field were noted. The physical properties of N2O were reviewed, along with systemic effects, human reproductive effects, animal studies, carcinogenicity, liver and kidney effects, and central nervous system effects. The concentrations of N2O in dental operatories measured during National Institute for Occupational Safety and Health (NIOSH) hazard evaluation and technical assistance studies were considered, and the sources and distribution of N2O in dental suites were discussed. Principles of controlling the exposures were discussed, including the use of scavenging machines and proper ventilation systems.
