초록

구치부 인접면 와동에서 유동성 복합레진 이장재의 두께가 치은측 변연의 미세누출에 미치는 영향을 평가하기 위하여 발거된 소구치 및 대구치의 근, 원심면에 box 형태의 와동(협설폭경 3mm, 근원심폭경 2mm, 상아법랑경계 상방 1mm에 치은 변연) 120개를 형성한 뒤, 무작위로 30개씩 선정하여 다음과 같은 4개의 군으로 분류하였다. group I- Tetric ceram 충전군(대조군) group II- 0.5mm 두께의 Tetric flow + Tetric ceram group III- 1.5mm 두께의 Tetric flow + Tetric ceram group IV- 2.5mm 두께의 Tetric flow + Tetric ceram 색소침투법으로 치은측 변연부 미세누출을 측정하여 다음과 같은 결론을 얻었다. 1. group II는 group I에 비해 낮은 미세누출을 보였다(p<0.05). 2. group III, IV과 group I 사이에는 통계적으로 유의한 미세누출의 차이 가 없었다(p>0.05). 3. group II는 group III, IV에 비해 낮은 미세누출을 보였다(p<0.05). 4. 모든 group에서 정도의 차이는 있으나 치경부에서 미세누출을 보였다. 이상의 결과로, 혼합형 복합레진으로의 구치부 인접면 와동 수복시 0.5mm 두께의 유동성 레진으로의 와동저 이장은 치은측 변연의 봉쇄능을 향상시켜 변연부 미세누출을 감소시킬 수 있는 방법으로 사료된다.

Abstract

This in vitro study aimed to investigate the influence of flowable composite lining with different thicknesses on the marginal quality. One hundred twenty cavities, each preparated with proximal box-type(3mm of bucco-lingual width, 2mm of mesio-distal depth and gingival margin of 1mm supra-CEJ) were randomly dived into four groups. group I : Tetric ceram filling alone(control group) group II: 0.5mm thickness Tetric flow + Tetric ceram filling group III: 1.5mm thickness Tetric flow + Tetric ceram filling group IV: 2.5mm thickness Tetric flow + Tetric ceram filling The followings are the results: 1. Group II showed significantly less microleakage compared to group I(control group)(p<0.05). 2. There was no statistically significant difference between group III, IV and group I(p>0.05). 3. Group II showed significantly less microleakage compared to group III, IV(p<0.05). 4. There was microleakage more or less in all group. It was concluded that 0.5mm flowable composite lining improved cavity adaptation and marginal sealing.
