Abstract
Dental caries has a multifactorial aetiology in which there is an interplay of three principal factors: the host(saliva and teeth), the microflora(dental plaque) and the substrate(diet), and a fourth factor time. There is no single test that takes into consideration all these factors and can accurately predict an individual's susceptibility to dental caries. The risk of dental caries can be evaluated by analysing and integrating several causative factors. The objective of the study was to clarify the relationship between caries activity and the status of caries of primary teeth and the relationship between the quantity of S. mutans in the dental plaque and the status of dental caries. Forty nine children ages 5 were examined with caries indices, Dentocult-SM and quantity of S. mutans. The results were as follows: All the survey results were similar with national means of 5-6 years Korean preschool children. The deft index of subjects was 5.46 and defs index was 9.81. There was 8.6% of negative, 10.9% of mild, 28.1% of moderate and 52.3% of active results at screening strip test. 8.6% was negative, 17.2% was mild, 33.6% was moderate and 40.6% was active in site strip test. The Spearman correlation coefficient was 0.775, and overall kappa index was 0.496 between screening strip test and site strip test. There also was a high correlation between caries incidence, Dentocult-SM test, and quantity of S. mutans. Dentocult-SM test as a caries activity test is a reliable method for measuring the status of dental caries in primary teeth.
개량형 Dentocult-SM 키트의 치아우식활성검사로서의 활용도와 임상적 지수와의 상관관계 그리고 민감도 및 특이도를 조사하기 위하여 만 5-6세 남녀아동 128명을 대상으로 구강검사와 screening strip 검사와 site strip 검사를 시행한 후 일정 부위의 치면세균막을 채취하여 뮤탄스 연쇄상구균 배양검사를 실시하여 다음과 같은 결론을 얻었다. Screening strip 및 site strip 검사 모두에서 우식활성도가 0에서부터 3까지로 증가할수록 아동들이 보유하고 있는 dft index와 dfs index는 각각 통계적으로 유의하게 증가하였고 아동들의 치면세균막 내의 뮤탄스 연쇄상구균 집락수 역시 우식활성도가 0에서 3으로 높아질수록 통계적으로 유의하게 수적인 증가를 나타내었다. Screening strip과 site strip 검사결과의 일치정도는 Spearman의 상관계수가 0.775 그리고 kappa 지수는 0.496으로 두 검사법의 일치도가 높았다. 또한 screening strip 검사의 민감도는 0.74-1.00, 특이도는 0.11-0.67로 나타났고, site strip 검사의 민감도와 특이도는 각각 0.48-1.00 및 0.11-0.66으로 계산되었다. 따라서 치과임상에서도 종래의 우식활성검사법들 보다 시간과 비용이 그리 많이 들지 않으며, 또한 각종 미생물학적, 생화학적인 기술이나 장비가 많이 필요치 않도록 간편하게 개량된 Dentocult-SM 검사법을 활용하면 치아우식증을 예측하는 진단학적인 측면이나 환자들을 대상으로 한 구강보건교육적인 측면에서 많은 도움이 될 수 있을 것으로 사료되었다.
