S. mutans에 대한 항균작용을 가진 천연물질에는 어떤 것들이 있는가? | S. mutans에 대해 항균작용이 있는 천연물질로는 황금14)과 백두옹 추출물15), 후박16), 일황련17), 고삼18), 오미자 추출물19), 지의류 추출물20) 등이 있는 것으로 보고되었다. | |
S. mutans의 성장 억제가 치아우식증 예방 및 감소로 이어지는 이유는 무엇인가? | S. mutans는 치면에 부착, 증식 및 산 생성과정을 거쳐 치아우식을 유발한다6). S. mutans는 균체외 또는 균체 표층에 치아우식의 유발효소인 glucosyltransferase(GTase)라는 효소를 분비하고 이 GTase가 음식물 중 자당(sucrose)을 분해하여 치면에 불용성 glucan을 형성한다. Glucan은 또한 구강내 다른 미생물들과 치면에 부착하여 치면세균막을 생성한다7,8). 여기에 치아우식 유발균과 혐기성 세균이 증식하면서 생성시킨 산에 의해 치아가 탈회되어 치아우식증이 유발된다9-11). | |
치아우식증의 원인은 무엇인가? | 치아우식증은 치면세균막내 세균, 음식물, 타액의 상호작용에 의하여 유발되는 다인성 질환으로서 치면세균막내 세균 중에서도 Streptococcus mutans(S. mutans)가 주된 원인균으로 알려져 있다5). |
