Abstract

The aim of this study was to evaluate the fluoride release and microhardness of Beautifil II as giomer(Group I), F2000 Compomer as compomer(Group II), GC Fuji II LC Capsule as resin-modified glass ionomer(Group III) and $Filtek^{TM}$ Z350 as composite resin(Group IV) according to time. Forty discs(5 mm diameter and 2 mm height) were prepared for each material. Each disc was immersed in 3 ml of de-ionized water within polyethylene tube and stored at $37^{\circ}C$. Evaluations were performed by pH/ISE meter for analysis of fluoride release and hardness testing machine for analysis of microhardness over 31 days. The results can be summarized as follows : 1. For all groups except group IV, the greatest fluoride release was observed after the first day of the study period and then dramatically diminished over time. On the 7th day of the study period, fluoride release level was stabilized. 2. Group III showed the highest fluoride release among test groups and then group II, group I were followed. Significant difference in cumulative fluoride release over 31 days was found between each groups. Group IV showed no fluoride release during study period. 3. Group IV showed the highest microhardness among test groups and then group I, group II, group III were followed. Significant difference in microhardness was found between each group, except between group I and group II. 4. After 31 days, microhardness was slightly diminished in every group. However, no significant difference was found.

Giomer는 글라스 아이오노머의 불소 유리 능력과 복합 레진의 물리적 성질을 동시에 가지고 있는 새로운 형태의 치과용수복 재료로 소개되고 있다. 그러나, 최근에 시판되고 있는 giomer의 실제 불소 유리 수준과 지속적인 불소 유리에 따른 물성 저하에 관한 연구는 아직까지 미흡한 실정이다. 이에 본 연구에서는 giomer의 시간 경과에 따른 불소 유리량과 미세경도를 측정하고 기존에 소개된 불소 유리 수복재료인 레진 강화형 글라스 아이오노머 및 컴포머와 비교하여 다음과 같은 결과를 얻었다. 1. 복합 레진을 제외한 모든 수복재에서 불소 유리가 관찰되었으며 첫째 날 유리량이 가장 높았고 이후 급격히 감소하여 7일 후부터는 완만하게 유지되는 양상을 보였다. 2. 31일간 누적 불소 유리량은 III군(레진 강화형 글라스 아이오노머)에서 57.941 ppm으로 가장 높았으며 II군(컴포머)에서 14.643 ppm, I군(giomer)에서 2.957 ppm 순으로 높은 유리량을 보였다. 3. 수복재의 미세경도는 IV군(복합 레진)에서 가장 높았으며 I군, II군, III군 순으로 높게 측정되었다. 4. 시간 경과에 따라 미세경도는 7일째 소폭 상승하였다가 31일째 다소 감소하는 양상을 보였으나 1일째와 비교시 차이는 없었다(p>0.05). 이번 연구 결과, giomer(Beautifil II)는 컴포머(F2000 Compomer)에 비하여 낮은 불소 유리량과 유사한 미세경도를 보였다.
