|
In order to evaluate the desensitization effect of two kinds of therapeutic dentifrice, the authors had examined 90´ hypersensitive teeth of 800 people aged from 20 to 60, who were divided into one control group and two experimental groups. The control toothpaste contained 0.76% SMFP and 45,0% of DCPD, and the one experimental toothpaste contained 5.0% of potassium nitrate, 0.76% SMFP, and 36.0% of DCPD, and the other one had 10.0% of strontium chloride and 38.0% Ca C03.
Baseline data was obtained by the checking of the response of pulp activity before study, and-the desensitizing effect was checked at each 4 weeks, 8 weeks and 12 weeks by electrical pulp tester. At the same time, the questionnaire was obtained in order to evaluate the subjective pain response before and after the, study. All the examinee were given with control and test toothpastes respectively and straight handled soft and medium bristled toothbrushes and directed to use the toothpastes and toothbrushes offered.
The obtained results were as follows:
1. The two kinds of therapeutic dentifrices containg strontium chloride and potassium nitrate had desensitizing effect of hypersensitive dentin.
2. The toothpaste containing strontium chloride reduced 77.27% of dentinal hypersensitivity and the other containing potassium nitrate reduced 82.61% of dentinal hypersensitivity in 12 weeks.
