Abstract
결론
본 연구는 최근 개량화된 상아질결합재인 Scotchbond multi-purpose와 GLUMA bonding
system 그리고 ALL-BOND 2를 대상으로 소구치 5급 레진수복시 발생하는 미세누출 양상
과 Streptococcus mutans에 대한 세균증식 억제효과 실험 결과 다음과 같은 결론을 얻었다.
1. 미세누출 양상은 각 실험군 모두 다양한 분포를 보였고 실험군간의 통계학적 유의 차는
존재하지 않았다(P>0.05).
2. 실험군중 Scotchbond multi-purpose와 GLUMA bonding system이 대조군(0.2%
chlorhexidine)과 비슷한 크기의 세균증식 억제대를 나타내었고, ALL-BOND 2 에서는 대조
군과 비교하여 작은 크기의 세균증식 억제대를 나타내었다.
3. 각 실험군 모두 aerobic chamber에서 배양시 anaerobic chamber의 배양시보다 더 큰 세
균증식 억제대를 보였다.
#초록#
The purpose of the present study was to evaluate the microleakage patterns and to
compare antimicrobial activity on Streptococcus mutans in three dentinal bonding agent.
Scotchbond multi-purpose, GLUMA bonding system and ALL-BOND were used as test
materials and 60 extracted premolars were selected.
For evaluation of microleakage patterns, methylene blue were penetrated and then cut,
microleakage patterns were graded by stereomicroscopic observation.
For comparison of antimicrobial activity, Streptococcus mutans (ATTC 27351) were
grown in brain heart infusion(BHI) broth, after inoculated, the disk diffusion test were
carried out.
After all plate were incubated for 48 hrs at 37 C, inhibitory zones were measured with
a sliding calipers. Antimicrobial test were repeated three times.
The results can be summarized as follows
1. The microleakage in each experimental groups showed various patterns and there
were no statistical significance in three dentinal bonding agent.
2. The mean values of the inhibition zones in Scotchbond and GLUMA were revealed
as same as in control. In ALL-BOND 2 the inhibition zones were less than control.
3. In every experimental groups, the inhibition zones were bigger in aerobic incubation
than anaerobic incubation.
