초록

복합레진 표면에 대한 APF gel 도포는 표면을 거칠게 하고 세균 부착을 증가시킨다. 본 연구는 Filtek Z250(FZ), Filtek Supreme Universal(FS)과, 실험적으로 나노충전재를 각각 0%, 3%, 6% 포함시켜 만든 복합레진(E0, E3, E6)으로 제작한 레진 시편을, APF gel을 적용한 군과 적용하지 않은 군으로 나누어 Streptococcus mutans의 부착량과 표면 조도를 측정하고 비교, 평가하여 다음과 같은 결과를 얻었다. 1. APF gel을 적용하지 않은 레진 시편에 대한 S. mutans 부착량은 FS에서 가장 적었고, FZ, E3, E6에 대한 부착량보다는 유의하게 낮았다(p<0.05). 2. 모든 레진군에서 APF gel을 적용한 레진 시편에 대한 S. mutans 부착량은 APF gel을 적용하지 않은 시편에 대한 부착량보다 유의하게 높았다(p<0.05). 3. APF gel을 적용한 레진 시편에 대한 S. mutans 부착량은 레진군간 유의한 차이를 보였으며(p<0.05), FS, FZ, E0, E3, E6의 순서로 높은 값을 보였다. 4. APF gel 적용 전이나 후에, 레진군간 표면조도의 차이는 유의하지 않았다(p>0.05).

Abstract

Topical application of APF gel can increase the surface roughness of resin composites and the roughened surfaces may allow increased bacterial accumulation and surface staining. Resin specimens of two proprietary resin composites, Filtek Z250(FZ) and Filtek Supreme Universal(FS), and experimental resin composites containing 0%, 3%, 6% nanofillers(E0, E3, E6) were fabricated and divided into two groups of the same number; APF treatment group and no treatment group. The amount of S. mutans adhered to specimens and the mean surface roughness(Ra) were measured. The results were as follows; 1. In no treatment group, the amount of S. mutans adhered to FS was the smallest. It was significantly different from those of FZ, E3, E6(p<0.05) although it was not significantly different from that of E0(p>0.05). 2. For all resin composites used, the amount of S. mutans adhesion in APF treatment group was significantly greater than that in no treatment group(p<0.05). 3. In APF treatment group, the amount of S. mutans adhesion was significantly different between materials(p<0.05), and increased in order of FS, FZ, E0, E3 and E6. 4. Difference of the surface roughness(Ra) between materials was not statistically significant in both no treatment group and APF treatment group(p>0.05)
