초록

본 연구는 불소 미방출 치면열구전색제 ConciseTM에 제조한 생체활성 유리 나노입자(bioactive glass nano particles: BGn)를 0.5, 1.0, 2.0 wt%를 첨가하여 새로운 치면열구전색제를 조성하고 세균부착실험을 통한 세균부착 억제 효과와 물성을 평가 하였다. 물흡수도와 용해도는 ISO 4049(2009) 규격에 맞추어 직경10 mm, 두께 2 mm 시편을 제작하여 무게를 측정하여 산출하였으며 세균부착효과는 S. mutans, S. aureus, E. coli 3개의 균주를 이용하여 평가하였다. 실험 결과 물흡수도는 BGn 첨가가 증가할수록 높은 값을 보였으며 용해도는 첨가될수록 낮은 용해도를 보였다(p<0.05). 세균부착실험 결과 대조군 ConciseTM 과 비교하여 BGn을 첨가한 S. mutans 실험군에서 다소 낮은 부착 양상을 보였으나 통계적 유의한 차이는 나타나지 않았으나, S. aureus 실험군과 E.coli 실험군에서는 통계적 유의한 차이를 보였다(p<0.05). 이는 BGn의 세균부착 억제 효과가 있음을 입증한 것이라 사료된다. 향후 BGn 첨가양에 따른 효율성과 폭 넓은 물성 연구가 필요할 것으로 사료된다.

In this study BGn-incorporated non-fluoride release of pit and fissure sealant ConciseTM was developed to improve the mechanical properties and promote antibacterial effect of fit and fissure sealant with the original material. The mechanical properties and antibacterial activity of BGn incorporating vary-ing amounts bioactive glass nano particles(BGn) (0,0.5,1.0 and 2.0 wt% in sealant) were characterized composition of the resulting were investigated.
The solubility to aid absorption was calculated by weighing specimens with a diameter of 10 mm and a thickness of 2 mm according to ISO 4049 (2009). The antimicrobial effect was evaluated using three strains of S. mutans, S. aureus and E. coli.
The absorbance of the test results was as high as the addition of BGn increased, and the lower the solubility as the solubility was added(p<0.05). Adhesion experiment results S. mutans in contrast to the control group ConciseTM, BGn-added experimental group showed a somewhat lower adherent surface but no statistically significant difference was observed (p<0.05). However S. aureus and E. coli statistical analysis indicated a significant difference for antibacterial agents between control and BGn containing(p<0.05). It seems that this BGn proved that even a antibacterial effect was demonstrated. Therefore, it was suggest that the additional effects of BGn and research on a wide range of substances.
