초록
본 연구는 임상에서 사용되는 진단도구들이 소아에서 우식위험도와 상관관계를 가지는지 여부를 확인하고, 소아에서 우식위험도를효과적으로 반영하는 지표가 무엇인지 알아보기 위함이다. 32명의 6세 미만의 소아를 두 군(Ⅰ군 : dmft < 6, Ⅱ군 : dmft > 6)으로 나누었다. Plaque-check PH을 이용해 치태의 pH를 측정하고, Saliva-check buffer를 이용해 타액의 pH와 완충능력를 측정하였다. S. mutans 검출을 위해 Saliva-check mutans와 Cytoperio analysis system을 이용하였다. 타액 완충능력은 두 군에서 유의한 차이를 보이며 dmft와 상관관계를 보였고, 타액의 pH와도 유의한 상관관계가 있는 것으로 확인되었다. 두 군 사이에 치태 pH, 타액 pH의 유의한 차이는 관찰되지 않으며 dmft와 상관관계를 가지지 않는 것으로 밝혀졌다. S. mutans 의 단일클론항체를 이용하는 Saliva-check mutans와 real-time PCR에 기반한 Cytoperio analysis system은 dmft와 유의한 상관관계를 가지고 있지 않는 것으로 밝혀졌다.
Abstract
This study aimed to compare chair-side test results for caries risk assessment and evaluate how well the tests reflect caries experience. The study was conducted on children aged < 6 years in primary dentition. Dental examination of children was conducted to determine the dmft index and subjects were divided into two groups : group Ⅰ (dmft < 6), group Ⅱ (dmft > 6). This study used four kinds of test kits (Plaque-check PH kit, Saliva-check buffer kit, Saliva-check mutans kit, Cytoperio analysis system). Saliva buffer capacity was significantly low in the high caries experience group (dmft > 6) and correlated with dmft index. Saliva pH level correlated significantly with saliva buffer capacity. The results showed that plaque pH and saliva pH levels had no correlation with dmft index. The Streptococcus mutans level measured by using the Saliva-check mutans and Cytoperio analysis system did not correlate with dmft index.
