A COMPARATIVE STUDY OF PLAQUE ACIDOGENESIS IN INDIVIDUALS RESIDING IN COMMUNITIES WITH AND WITHOUT FLUORIDATED WATER
Abstract
The ability of dental plaques to produce acid in response to a sugar rinse in fluoridated and non-fluoridated communities was indirectly evaluated by measuring plaque pH with an antimony electrode attached to a Corning pH meter. One hundred forty-four seventh and eighth grade students were evaluated in Albany, Oregon shortly before this city fluoridated its water supply and again three months after fluoridation. One hundred thirty-one similar students were evaluated in Corvallis, Oregon, a city which has had fluoride in its water for about fifteen years. One hundred eighty-one students were evaluated in Lebanon and Canby, Oregon, communities without fluoride. In general it was found that students residing in fluoridated communities produced less acid than those living in the other communities. The magnitude of the depression was about 0.2 pH units, which was statistically significant (t.95). It is unlikely that this degree of inhibition of acidogenesis is adequate to prevent cariogenic acidity. Once developed, such a mouthwash would be of great value to men in the field.
