Abstract

|
|
The author had performed the physico-chemical experiments and clinical evaluation for the newly developed dentifrice contained with such ingredients as zeolite of soft granule and sodium metaphosphate, in order to increase the plaque removal effect on the interdental area and the stain removal effect and to inhibit the calculus formation. The study evaluated the physico-chemical experiments of zeolite for the plaque adsorption effect, the granule breakage test, the cleaning effect of interdental area and the stain removal effect and the clinical evaluation participated by 90 young adults volunteers whoo provided a consent for their participation.
The obtained results were follows
1. The plaque adsorption capacity of zeolite was highly effective than any other abrasives like DCPD(dicalcium phosphate, dihydrate) and calcium carbonate. DCPD was more effective than calcium carbonate.
2. The dentifrice containing sodium metaphosphate and zeolite was effective in the cleaning of interdental area.
3. The granulated zeolite was broken with the 200~300g/cm2 of manual toothbrushing power.
4. The result of stain removal test using hydroxyapatite disc was significant difference between the dentifrice containing sodium metaphosphate and zeolite and the control by 10.27 at the ? Lvalue(p (0.05).
5. in clinically, the dentifrice containing sodium metaphosphate and zeolite was highly effective in the plaque removal effect among three dentifrices and the dentifrice containing sodium metaphosphate was more effect than the control(p (0.05). The dentifrice containing sodium metaphosphate and zeolite was clinically effective in the initial inhibition of calculus formation(p (0.1).
