Abstract

The purpose of this study was to measure the polymerization shrinkage and hygroscopic expansion of resin-based temporary filling materials and to evaluate microleakage at the interface between the materials and cavity wall. Five resin-based temporary filing materials were investigated: Fermit (Vivadent), Quicks (Dentkist), Provifil (Promedica), Spacer (Vericom), Clip (Voco). Caviton (GC) was also included for comparison. Polymerization shrinkage of five resin-based temporary filling materials was measured using the bonded disc method. For the measurement of hygroscopic expansion, the discs of six cured temporary filling materials were immersed in saline and a LVDT displacement sensor was used to measure the expansion for 7 days. For estimating of microleakage, Class I cavities were prepared on 120 extracted human molars and randomly assigned to 6 groups of 20 each. The cavities in each group were filled with six temporary filling materials. All specimens were submitted to 1000 thermocycles, with temperature varying from $5^{\circ}C/55^{\circ}C$. Microleakage was determined using a dye penetration test. The results were as follows: 1. Fermit had significantly less polymerization shrinkage than the other resin-based temporary fill ing materials. Fermit (0.22%) < Spacer (0.38%) < Quicks (0.64%), Provifil (0.67%), Clip (0.67%) 2. Resin-based temporary filling materials showed 0.43-1.1% expansion in 7 days. 3. Fermit showed the greatest leakage, while Quicks exhibited the least leakage. 4. There are no correlation between polymerization shrinkage or hygroscopic expansion and microleakage of resin-based temporary filling materials.

본 연구의 목적은 수 종의 레진계 임시수복재의 중합수축 및 수화팽창을 측정하고 레진계 임시수복재와 와동면 사이의 미세누출을 평가하고자 하였다. 본 실험의 재료는 5종의 광중합형 레진계 임시충전재 Fermit, Quicks, Provifil, Spacer, Clip와 대조군으로 석고계 충전재 Caviton을 사용하였다. 'Bonded disc method'를 이용하여 중합수축을 측정하였고, 미리 중합된 디스크 형태의 시편을 생리식염수에 담그고 LVDT로 7 일 동안 수화팽창을 기록하였다. 발거된 120개의 상, 하악 대구치에 1 급 와동을 형성한 후 각각 20개씩 6개의 군으로 나누어 각 재료를 충전한 후, 1000 회의 Thermocycling을 실시하고 2% methylene blue 염색 용액을 이용하여 미세누출을 평가하였다. 연구결과는 다음과 같다. 1. Fermit의 중합수축이 가장 적었고 (0.22%) Spacer (0.38%), Quicks (0.64%) Provifil (0.67%), Clip (0.67%) 의 순이었다. 2. 모든 재료는 24 시간 이내에 급격한 수화팽창을 나타냈고 7 일 후 수화팽창은 Caviton이 가장 컸다 (11.5%). 레진계 임시수복재는 0.43-1.1%가량 팽창하였다. 3. Fermit의 미세누출이 가장 많았으며 Quicks의 미세누출이 가장 적었다. Spacer와 Clip은 Caviton과 비슷한 정도의 미세누출을 보였다. 4. 중합수축 또는 수화팽창과 미세누출 사이의 직접적 인 상관관계는 관찰할 수 없었다.
