Abstract

The purpose of this study was to compare the effect on marginal leakage of a resin surface sealant (Biscover) applied before or after polymerization of composite resin to unsealed composite restorations. Thirty Class V cavities with the occlusal margin in enamel and cervical margin in dentin or cementum were prepared on the buccal surfaces of sound extracted molars and restored with a microfilled light-cured composite resin (Micronew). Restorations were randomly assigned into one of three equal groups (n = 10): a control group - no surface sealing, group 1 - applied Biscover after polymerization of the composite resin. and group 2 - applied Biscover before polymerization of the composite resin. Specimens were thermocycled, immersed in a $20\%$ methylene blue solution for 4 hoots, sectioned longitudinally, and analyzed for leakage at the occlusal and gingival margins. The results of this study were as follows 1. In sealed group, group 2 showed higher microleakage than group 1 at both occlusal and gingival margins. but there was no significant difference between two groups (p > 0.05). 2. Unsealed control group showed a little higher microleakage than sealed group at occlusal margins, and a little Higher or similar microleakage than sealed group at gingival margins (p > 0.05) 3. Control group and group 2 showed significantly less microleakage at the occlusal margins, but group 1 showed no significantly difference between microleakage at the occlusal and gingival margins.

본 연구는 복합레진을 광조사하기 전과 광조사한 후에 표면 전색제인 Biscover를 적용하여 이들에 대한 변연 미세누출을 평가하고, 또한 표면 전색제를 적용하지 않는 복합레진 수복물과의 미세누출 차이를 비교하기 위하여 시행하였다. 30개의 발거된 대구치의 협면 치경부에 5급 와동을 형성하여 다음과 같이 3개의 군으로 분류하였다; 대조군은 복합레진 표면에 Biscover를 적용하지 않은 군, 1군은 복합레진을 광조사하고 마무리한 후 Biscover를 적용한 군, 2군은 복합레진을 광조사하지 않고 Biscover를 적용한 군. 각 군의 시편은 실온의 증류수에 48시간 동안 보관한 후 $5^{\circ}C$와 $55^{\circ}C$에서 1,000회의 열 순환을 시행하고 2% methylene blue용액에 4시간 동안 침적시켰다. 20배율의 광학 입체현미경 하에서 각 군의 교합면측과 치은측 변연의 색소침투 정도를 관찰하여 미세누출 점수를 얻은후, 각군 간의 유의성을 검정하여 다음과 같은 결과를 얻었다. 1. 2군은 1군보다 교합면측과 치은측 변연 모두에서 높은 미세누출을 보였으나 통계학적으로 유의한 차이는 없었다 (p > 0.05). 2. 대조군은 교합면측 변연에서 1군과 2군보다 약간 높은 미세누출을 보였으며 , 치은측 변연에서 1군보다 약간 높게 그리고 2군과 비슷한 미세누출을 보였다 (p > 0.05). 3. 대조군과 2군은 교합면측 보다 치은측 변연에서 통계학적으로 높은 미세누출을 보였으며 (p < 0.05), 1군은 교합면측과 치은측의 변연 미세누출 간에 통계학적인 차이를 나타내지 않았다 (p > 0.05). 본 연구를 종합하면, Biscover는 중합된 복합레진 표면에 적용할 경우 치은측 변연의 미세누출을 감소시키는데 효과적이었다.
