초록
본 연구는 최근 새롭게 개발된 fTCP와 현재 치과임상에서 재광화 크림으로 널리 사용되고 있는 CPP– ACP의 재광화 효과를 비교하기 위하여 QLF-D를 이용하여 인공우식병소에서 fTCP와 CPP-ACP의 무기질소실변화를 평가하고자 하였다. 실험에 사용된 우치시편은 탈회용액에 10일간 보관하여 인공우식병소를 형성하였고, 무작위로 두 군으로 분류하였다. 1군은 10% CPP-ACP가 포함된 Tooth Mousse 군이고, 2군은 fTCP가 포함된Clinpro Tooth Creme군이다. 두 종류의 치아크림을 각각 탈회병소에 바르고 1주일간 인공타액에 침전 후 QLF-D 를 이용하여 병소의 형광소실량(⊿F)을 평가하였다. QLF-D 분석결과 Tooth Mousse군은 처치 후에 ⊿F값과 ⊿ Fmax값이 각각2.65, 6.63 증가하여 무기질 소실이 통계적으로 유의하게 감소(p<0.05)한 반면, Clinpro Tooth Creme군은 통계적으로 유의한 차이가 없었다. 또한 ⊿Fmax값에서는 처치 후 Tooth Mousse군이 Clinpro Tooth Creme군에 비해 통계적으로 유의하게 감소하였다(p<0.05). 그러므로 10% CPP-ACP가 포함된 Tooth Mousse는fTCP가 포함된 Clinpro Tooth Creme보다 초기우식병소의 재광화 치료에 더욱 효과적이다.
Abstract
This study was to evaluate the change of mineral loss of fTCP and CPP-ACP in artificial caries lesions using QLF-D to compare the remineralization effect of recently developed fTCP and CPP-ACP, which is widely used as a remineralization cream in current dental clinics. Bovine specimens used in this study formed the artificial caries lesion immersing in demineralization solution for 10 days and were divided randomly into the following two groups; Group 1- Tooth Mousse containing 10% CPP-ACP, Group 2- Clinpro Tooth Creme containing 950ppm NaF and fTCP. Two tooth paste were applied to the artificial caries lesion of specimens and they were immersed in artificial saliva for 1 week. Mineral loss of artificial caries lesion was evaluated by fluorescence loss (⊿F) values using QLF-D. QLF-D analysis showed that the ⊿F and ⊿Fmax value increased 2.65 and 6.63, respectively, in the Tooth Mousse group, and the mineral loss decreased statistically significantly(p<0.05). However, Clinpro Tooth Creme group had no statistically significant difference. ⊿Fmax value of Tooth Mousse group was statistically significant difference compared to the Clinpro Tooth Creme. Therefore, the Tooth Mousse containing 10% CPP-ACP is more effective than Clinpro Tooth Creme containing fTCP in the treatment of remineralization of artificial caries lesions.
