Abstract

PURPOSE: The purpose of this study was to evaluate the effects of hydroxyapatite containing toothpaste for patients who received periodontal therapy and felt hypersensiptivity. MATERIAL AND METHODS: After application of toothpaste, patients were evaluated for VAS(Visual Analog scale) scores to a cold stimulate on baseline, 1 week, and 4 weeks. VAS scores were analyzed by statistical methods. RESULTS: The results of this study were as follows. 1. VAS scores in control group on baseline, 1 week, 4 weeks were 5.39+/-2.05, 4.75+/-2.00, 4.21+/-1.75. 2. VAS scores in experimental group on baseline, 1 week, 4 weeks were 5.61+/-2.37, 4.81+/-2.46, 4.08+/-2.54. 3. Decrease of VAS scores on hypersensitivity after 1week was 0.64+/-0.49(p<.0001) in control group, 0.80+/-1.65 (p<.0001) in experimental group. 4. Decrease of VAS scores on hypersensitivity after 4weeks was 1.18+/-1.60(p<.0001) in control group, 1.53+/-1.88 (p<.0001) in experimental group. 5. When compared, decrease of VAS scores after 1 week between 2 groups were not statistically different(p=0.2622). 6. When compared, decrease of VAS scores after 4 weeks between 2 groups were not statistically different(p=0.1219). CONCLUSION: It was confirmed that hydroxyapatite containing toothpaste have the similar effect with pre-existing proven dentifrice for relieving teeth hypersensitivity.
