Abstract
결론
화학중합형 및 광중합형의 Glass Ionomer Cement 수복재 및 와동이장재의 항균성을 비
교평가할 목적으로, 한천평판 배지확산법을 이용하여 주된 우식유발 균주인 Streptococcus
mutans에 대한 GIC 재료들의 세균증식억제력을 관찰하여 다음과 같은 결론을 얻었다.
1. 모든 Glass Ionomer Cement 수복재 및 와동이장재에서 항균성이 인정되었다.
2. Glass Ionomer Cement 수복재의 경우, Vitremer의 세균증식 억제대가 가장 크고
Ketac-Silver와 Ketac-Fil은 유사한 수준이었으며, Fuji Ⅱ LC에서 가장 작게 나타났다
(P<0.05).
Glass Ionomer Cement와동이장재의 경우에는 Vitrebond, Fuji Lining Cement, Fuji
Lining LC 의 순으로 나타났으며(P<0.05), 불소함유 레진 와동이장재인 Time-line에서는 세
균증식억제효과를 관찰할 수 없었다.
4. 24시간동안 생리식염수에 담근후 적용한 경우, 모든 시료에서 세균증식억제대가 나타나
지 않았다.
5. 광중합형 GIC 시료와 화학중합형 GIC 시료간의 항균성의 차이는 규명할 수 없었고,
GIC 와동이장재는 GIC 수복재에 비하여 항균성이 큰 것으로 나타났다 (P<0.05).

Microorganisms may exist at the interface between prepared cavity and restorative
material due to microleakage or incomlplete removal of carious lesion, and this could
result in pulpitis or secondary caries. In this perspective, the antibacterial potential of
the restorative materials and cavity liners would be advantageous. The antibacterial
effect of glass ionomer cements has already been proven but only partially, and there
has not been much of a general comparative evaluation of the antibacterial effect of the
materials being provided in an increasing number in these days.
This research was intended to compare the antibacterial activity of glass ionomer
restorative materials and glass ionomer cavity liners and resin cavity liner by employing
agar diffusion test. The antibacterial activity of the Glass inomer materlals including
conventional chemically-cured glass ionomer cement, glass cermet cement, and
light-cured glass ionomer cement to Streptococcus mutans, a leading causative
microorganism in caries, was evaluated, which yielded the results as follows.
1. All the glass ionomer materials tested proved to have antimicrobial effects.
2. In the case of glass ionomer restorative materials, the bacterial inhibition zone was
largest in the Vitremer and smallest in Fuji II LC. Ketac-Silver and Ketac-Fil exhibited
similar values (P<0.05).
3. In the case of glass ionomer cavity liners, it was in the order of Vitrebond, Fuji
Lining Cement, Fuji Lining LC, with the latter showing the smallest zone (P<0.05). On
the contrary, Timeline which is a kind of F-added resin cavity liners showed no
antibacterial activity.
4. No material showed antibacterial activity when applied after immersed in saline for
24 hrs.
5. It was impossible to clarify the difference in antibacterial effect between light-cured
and chemically-cured GIC materials and GIC cavity liners exhibited greater antibacterial
effects comparing with GIC restorative materials (P<0.05).
