Abstract

The purpose of this study was to evaluate the correlation between caries experience, Quantitative Light-Induced Fluorescence-Digital (QLF-D) redings and new caries activity test (Cariview) results in preschool children. Fifty-seven healthy kindergarten children (male 28, female 29) were participated this study. The calibrated dentist investigated the caries experience of children and new caries activity test. Cariview samples were incubated in the activated medium at $37^{\circ}C$ for 48 hours. All QLF-D taking and readings were performed by one experienced and trained operator under identical conditions in a dental unit chair located in a darkened room. Analysis range was limited to the maxillary and mandibular anterior teeth. QLF-D redings (white spot and dental plaque) were analysed using QLF system. The dft index had a relatively high correlation with the QLF-D redings (white spot: r=0.617, simple plaque score: r=0.500) (p<0.01). Also, there was significant correlation between dft index and the Cariview score (r=0.286) (p<0.05). However, the Cariview score had no significant correlation between dt index and ft index (p>0.05). QLF-D can be evaluated objectively the initial caries lesions and dental plaque correlated with caries experience. Therefore, QLF-D will be useful to the study of caries prediction.

본 연구는 초기우식 진단장비인 QLF-D와 새로운 치아우식활성 검사법인 Cariview를 우식예측 연구에 활용할 수 있는지를 평가하기 위하여, 만 3세 아동 57명을 대상으로 구강검사를 실시한 후 우식경험도를 분석하고 이들 간의 상관성을 평가하여 다음과 같은 결과를 얻었다. 1. 연구대상자의 우식경험도 조사 결과, 우식경험유치지수는 평균 1.84였으며, QLF-D를 이용한 분석 결과는 치면 세균막 부착에 대한 점수가 1.47이었고, 연구대상자 당 평균 1개 정도의 초기우식병소($0.96{\pm}1.21$)가 있는 것으로 나타났다. 또한 Cariview 검사에서 산생성능은 평균 27.52로 나타났고, 연구대상자 중 68%가 저위험군에 속하는 것으로 파악되었다. 2. 우식경험유치지수와 초기우식병소 개수의 상관계수가 0.617, 치면세균막 부착정도(SPS)와는 상관계수가 0.500으로 비교적 강한 상관관계를 확인할 수 있었고(p<0.01), 우식경험유치지수와 Cariview 결과(0.286) 간에는 유의한 양의 상관관계가 나타났다(p<0.05). 그러나 우식유치지수, 우식경험충전유치지수에서는 Cariview 점수와의 상관관계를 확인할 수 없었다. 이상의 결과를 종합해보면, QLF-D를 이용하여 분석한 치면세균막 점수와 초기우식병소는 우식예측에 가장 중요한 영향을 주는 과거 우식경험에 높은 상관성을 보였으므로, 초기우식병소 탐지와 치면세균막 부착 정도를 동시에 파악할 수 있는 QLF-D는 우식예측 연구에 유용한 장비로 활용할 수 있을 것이다.
