초록

Fuji VII은 제 1, 2대구치의 조기보호를 목적으로 소개되었으며 기존의 글래스 아이오노머 시멘트보다 많은 양의 불소를 유리하면서도 점도가 낮아 흐름성이 우수하고 부가적인 산부식 과정이 필요 없는 특징 때문에 치은판개가 일부 덮인 제 1, 2대구치의 교합면이나 일부만 노출된 대구치 협면구의 우식 예방과 재광화에 유용하다고 하였다. 본 연구의 목적은 Fuji VII의 재광화 효과를 알아보고 기존의 글래스 아이오노머 시멘트, 레진 강화형 글래스 아이오노머 시멘트, 콤포머와 복합레진의 재광화 효과를 비교하고자 하였다. 이에 인공적으로 형성한 우식을 가진 42개의 치아에 Fuji VII, Fuji II, Fuji II LC improved F2000, $Filtek^{TM}$ Z250의 재료를 충전하고 편광현미경 상에서 충전 직후와 4주 후 탈회 면적을 측정하였으며 두 면적의 차이를 비교하여 다음의 결과를 얻었다. 1. 재광화 정도는 Fuji VII, Fuji II, Fuji II LC improved, F2000, 대조군, $Filtek^{TM}$ Z250 순으로 크게 나타났으며, 글래스 아이오노머 계통의 Fuji VII, Fuji II, Fuji II LC improved에서 F2000, $Filtek^{TM}$ Z250, 대조군에 비해 유의한 재광화가 나타났다(p<0.05). 2. Fuji VII과 Fuji II Fuji II LC improved 간에는 유의한 재광화 정도의 차이는 관찰되지 않았다(p>0.05).

Fuji VII is a glass-ionomer cement specially targeted for early protection in erupting first and second molars. Properties of Fuji VII such as very high level of fluoride release, low viscosity and no need to preliminarily etch the substrate would be useful to erupting molars with primary pit and fissure caries or hypoplastic area for preventive goal or remineralization. The purpose of this study were to evaluate remineralization of Fuji VII glass ionomer cement and to compare with one of other restorative materials such as conventional glass ionomer cement, resin-modified glass ionomer cement, compomer and composite resin. Forty-two extracted human molars were used for this study. All teeth were immersed in demineralizing solution for 48 hours after Class V cavity preparation was made on sound proximal surface. The teeth were randomly divided into six groups and restored with Fuji VII, Fuji II, Fuji II LC improved, F2000, $Filtek^{TM}$ Z250 and control group was unrestored. The middle area with $130{\pm}20{\mu}m$ thickness was separated from specimen using microtome and demineralized area was photographed under polarized microscope. Separated area was relocated to specimen and stored in artificial saliva, After four weeks, changes of demineralized area were observed and compared to them restorated immediately. The results from the this study can be summarized as follows ; 1. Fuji VII, Fuji II, Fuji II LC improved have more prominent remineralization effect than F2000, $Filtek^{TM}$ Z250, control group. 2. No significant differences in remineralization effect are seen between Fuji VII and Fuji II, Fuji II LC improved.
