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.
Materials & 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. (J Korean Acad Periodontol 2008;38:1-6)
