Dental hygienists' knowledge, opinions, and use of pit and fissure sealants: a comparison of two states.

This article reports results of a study of 563 practicing Minnesota and Wisconsin dental hygienists' knowledge, opinions, and use of pit and fissure sealants. The study was carried out six months prior to the 1983 NIH Consensus Development Conference on Dental Sealants in the Prevention of Tooth Decay. It therefore provides baseline information for two states prior to the initiation of widespread public information about the positive value of sealants that occurred as a result of that conference.
