The purpose of this study was to evaluate the effects of therapeutic toothpaste containing tetrasodium pyrophosphate, vitamin-E and hydrogen peroxide on the whitening. 55 adult male and female subjects aged 20 to 29 year-olds completed 2-week, double-blind clinical study. Subjects were divided by two balanced groups according to baseline tooth brightness. Trubyte Bioform shade guide was used to score the tooth brightness. There was statistical significance of the brightness changes between the therapeutic toothpaste and the control toothpaste after 2 weeks(P<0.05). This result suggest that therapeutic toothpaste containing tetrasodium pyrophosphate, vitamin-E, and hydrogen peroxide be effective on improving tooth whitening.

본 연구의 목적은 첫째, 55세이상성인을 대상으로 구강보건영향지수 중 물리적동통의 유병률을 파악하고, 둘째, 55세이상성인의 구강건강충격지수 중 물리적동통의 연관요인을 파악함에 있다. 조사대상자는 2000년 국민구강건강조사시 층화무작위추출법으로 표본추출된 4,250명의 55세이상성인집단 중에서 본 연구의 목적에 동의한 1,098명의 55세이상성인이었고, 조사방법은 전화면접조사법이었다. 면접문항은 구강건강충격지수 중 물리적동통에 관련된 9개의 문항와 성, 연령, 거주지역 및 의치장착여부등에 관한 4문항을 합하여 총 13문항이었고, 동통정도의 웅답은 5점리커트척도(0-4)룰 이용하여 기록되었다. 동통유병를은 동통정도 0-1을 동통무경험자로, 동통정도 2-4를 동통유경험자로 하였고, 총물리적동통정도(PPS)는 9개의 개별물리적동통정도의 합으로 최저 0점에서 최고 36점에 분포하도록 하였다. 동통유병률에 관한 연관요인을 파악하기 위하여 다변량 로지스틱회귀분석을 실시하였고, 총물리적동통정도에 관한 연관요인을 파악하기 위하여, 다변량 선형회귀분석을 실시하였다. 두통, 치은동통, 과민성치아 둥에 관한 유병률은 각각 6.8%, 17.2% 및 26.0% 이었다. 여자는 남자에서 보다 두통유병률의 가능성이 2.3배(95% 신뢰구간=1.33,3.99) 높았고, 치은동통유병률의 가능성은 1.4배(95% 신뢰구간=1.01, 1.97) 높았다. 국부의치장착자는 의치비장착자보다 치은동통유병률의 가능성이 1.8배(95% 신뢰구간=1.20, 2.58) 높았으며, 의치장착은 총물리적동통정도를 1.58 증가시겼다(확률값=0.001). 총괄적으로, 두통유병률과 과민성치아유병률의 연관요인은 성이었고, 치은동통유병률의 연관요인은 성과 의치장착이었다.

30 adult male and female subjects completed 4-week, double-blind clinical study comparing the effect on gingivitis of the dentifrice containing 0.76% sodium monofluorophosphate and 3.0% carbamide peroxide. Subjects were divided by two balanced groups according to baseline gingivitis scores. Gingivitis index was scored by Lo¨e-Silness' Gingival index. Microhardness of tooth enamel of the dentifrice containing 0.76% sodium monofluorophosphate and 3.0% carbamide peroxide and the dentifrice containing 0.38% sodium monofluorophosphate, 0.11% sodium fluoride, 0.5% hydroxyapatite, and 3.4% tetrasodium pyrophosphate was measured by microhardness tester(Shimadzu corporation Model, HMV-2000 No. 33100410, Japan) before and after 20,000 strokes with brushing machine, Brightness of tooth enamel of the dentifrice containing 0.76% sodium monofluorophosphate and 3.0% carbamide peroxide and the dentifrice containing 0,38% sodium monofluorophosphate, 0.11% sodium fluoride, 0.5% hydroxyapatite, and 3.4% tetrasodium pyrophosphate was measured by colorimeter before and after 200 strokes with brushing machine. The obtained results were as follows: 1. The dentifrice containing 0.76% sodium monofluorophosphate and 3.0% carbamide peroxide was shown to provide a statistically significant reduction in gingivitis than the control dentifrice after 4 weeks(P <0.05). 2, There was no statistical significant change in the microhardness between the dentifrice containing 0.76% sodium monofluorophosphate and 3.0% carbamide peroxide and the control dentifrice(P≥0.05). 3. There was no statistical significance of the microhardness changes between the dentifrice containing 0.38% sodium monofluorophosphate, 0.11% sodium fluoride, 0.5% hydroxyapatite, and 3.4% tetrasodium pyrophosphate and the control dentifrice(P≥0.05). 4. There was statistical significance of the brightness changes between the dentifrice containing 0.76% sodium monofluorophosphate and 3.0% carbamide peroxide and the control dentifrice(P<0.05). 5. There was statistical significance of the brightness changes between the dentifrice containing 0.38% sodium monofluorophosphate, 0.11% sodium fluoride, 0.5% hydroxyapatite, and 3.4% tetrasodium pyrophosphate and the control dentifrice(P<0.05).
