Abstract

|
|
The purpose of this study was to compare the anticarious effect by kinds of fluoride - containing dentifrices and kinds of fluorides contained in dentifrices. The author randomly selected 9 different fluoride containing dentifrices which were saled in Korea. Bovine enamel slabs involved early carious lesions were treated with flouride - containing dentifrices, NaF and SMFP solution by pH-cycling method.
Surface hardness and fluoride contents of bovine enamel were measured for dentifrice treated groups in comparison with fluoride treated groups control group.
A comparative study of the obtained results led to the following conclusions.
1. The fluoride contents of Perioe doctor^ⓡ and Amore ion^ⓡ groups were higher than that of the other fluoride - containing dentifrice groups. But that of Close up^ⓡ was lower than of others but Acacia^ⓡ group.
2. The dentifices containing sodium monofluorophosphate and sodium fluoride were higher on fluoride content than those containing NaF, SMFP, respectively.
3. Fluoride - containing dentifices were more effective on enhancing surface hardness than control gourp.
4. NaF solution was more effective on fluoride content than SMFP solution. Two fluoride solutions were the same effect on surface hardness, but they were more effective on surface hardness than control group.
