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. Fifty-six seventh and eighth grade students were evaluated in Albany, Oregon shortly before this city fluoridated its water supply and again three months after fluoridation. Fifty-eight similar students were evaluated in Corvallis, Oregon, a city which has had fluoride in its water for about fifteen years. Forty-three students were evaluated in Canby, Oregon, a community 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 however, if supplemented by a daily mouthwash containing fluoride, it may. Once developed, such a mouthwash would be of great value to men in the field. Author
