Abstract
The purpose of this study was to assess relative tooth abrasivity and to measure effective fluoride concentration of dentifrices selling in Korea for help consumer´s selection of suitable dentifrice.
Assessment of the abrasion on tooth produced by different dentifrices were carried out on bovine teeth in the laboratory and tested by radioactive dentin abrasion method. And total soluble fluoride concentrations within the dentifrices was determined using fluoride ion selective electrode with standard curve obtained from standard solutions of known fluoride concentration. 10 dentifrice samples were stored at 490C for 15 weeks and the measurements were made for each dentifrice in 1 week, 2 weeks, 3 weeks, 13 weeks and 15 weeks and 11 dentifrice samples were stored at 40.60C for 3 weeks and the measurements were made for each dentifrice in 1 week and 3 weeks.
Tooth abrasivity of selling dentifrices is suitable for toothbrushing but dentifrice which recommended for patient who have tooth abrasion or erosion was somewhat high abrasivity level. Effective fluoride concentrations of selling dentifrices were maintained generally optimal level. But some dentifrices contaning CaCO3 as abrasive were decreased as time elapsed.
It was suggested that relative tooth abrasivity must be marked on package and fluoride level should be maintained acceptable level in dentifrices for consumer´s selection of suitable dentifrice.
