Abstract
[한글]

본연구는 제Ⅴ급 와동 변연부의 미세누출을 평가하기 위하여 각기 결합 기전이 다른 세 종류의 상아질 접착제를 선정하여 사용하였다.

발거된 100개 치아를 대조군과 실험군 그리고 positive control group으로 나누었으며 대조군과 실험군은 각각 23개의 치아로 구성했으며, positive control group은 8개의 치아로 구성했다. 실험군은 각각 All-Bond 2군, Gluma군, Scotchbond MP군이며 대조군으로는 Vitrebond를 사용하였다. 복합 레진 충전하방으로 산부식, primer처리, adhesive resin처리를 하지 않은 군을 positive control group으로 사용하였다. 연마가 끝난 시편은 5℃와 55℃에서 1000회 온도 변화를 시행하고 2% methylene blue dye용액에 침윤시겨 37℃항온기에 24시간 보관하였다.

치아를 협설측으로 절단하여 현미경을 사용한 20배율로 색소 침투도를 비교, 관찰한 결과 다음과 같은 결론을 얻었다.

1. 모두 법랑질 변연이 상아질변연에서 보다 낮은 색소 침투도를 보였다.(P<0.05)

2. 법랑질 변연에서 All-Bond 2가 Gluma에 비해 다소 높은 색소 침투도를 보였으나(Mann-Whitney analysis, P<0.05), All-bond 2, Gluma, Scotchbond MP사이에는 비슷한 정도의 색소 침투도가 나타났으며 (Kruskal-Wallis analysis, P>0.05), 대조군인 Vitrebond에 비하여 낮은 색소침투도를 보였다(Mann-Whitney-analysis, P<0.05).

3. 상아질 변연에서 All-Bond 2가 Gluma에 비해 낮은 색소침투도를 보였으나(Mann-Whitney analysis, P<0.05), All-bond 2, Gluma 와 Scotchbond MP사이에는 비슷한 정도의 색소 침투도가 나타났으며(Kruskal-Wallis analysis, P>0.05) 대조군인 Vitrebond와도 비슷한 정도의 색소침투도를 보였다(Mann-Whitney analysis, P>0.05).

4. 상아질 접착제의 꾸준한 연구에도 불구하고 여전히 상아질 변연 누출은 개선되지않고 있다.





[영문]

This study aimed to evaluate the marginal microleakage of Class Ⅴ cavities of All-bond 2 (Wet-bonding system). Gluma(Adhesion of resin to exposed collagen fibers), and Scotchbond Multi-purpose(Mild Etching System).

Hundred extracted human teeth divided into a control and three experimental groups consisting of eight teeth.

The experimental group was further subdivided into All-bond2, Gluma and Scotchbond MP groups, Vitrebond served as the control.

The positive control group consisted of specimens filled with resin and with no etching, primer and bonding procesure.

Polished specimens underwent temperature changed from 5℃ to 55℃ a thousand times.

After thermocycling, speciemens were placed in 2% methylene blue dye solution for 24 hours in an incubator set at 37℃.

The teeth were sectioned buccolingually and the degree of dye penetration was observed with a stereomicroscoped (* 20).

The following results were obtained.

1. Both the control and the experimental group showed a lower degree of dye penetration on enamel than on dentin margins (p<0.05)

2. Gluma exhibited a statistically significant lower degree of dye penetration than All-bond 2 on enamel margins (p<0.05)

Scotchbond MP also exhibited a lower degree of dye penetration than All-bond2 but was no statistically significant.

Gluma and Scotchbond MP exhibited a similar degree of dye penetration.

3. The degree of dye penetration of All- bond 2, Gluma and Scotchbond MP showed no statistically singnificance on enamel margins but was significantly lower than in the control using Vitrebond.

4. All-bond 2 exhibited a statistically significant lower degree of dye penetration than Gluma on dentin margins. All-bond 2 and Scotchbond MP showed a similar degree of dye penetration.

5. The degree of dye penetration of All-bond 2, Gluma and Scotchbond MP showed no statistically significance on dentin margins. There was neither a statistical significance with the control.
