ICDAS(International Caries Detection and Assess-ment System)
특징 )
1. 병변의 activity 는 치아표면에 형성된 plaque 의 질감 , 색에 근거하여 판단
2. Prescriptive method
Specific criteria 를 근거로 치아우식 진행 등급책정
ICDAS(International Caries Detection and Assess-ment System)
• 각 score 의 총합으로 activity 판단• Total score of 4~7 : inactive lesion• Total score > 7 : active lesion
ICDAS(International Caries Detection and Assess-ment System)
• Resin block 에 매몰 후 slice 하여 검사 ( 두께 약 250μm , stere-omicroscope 이용 )
• 5-point scale– D0 = no caries– D1 = caries lesion limited to the outer half of the enamel– D2 = caries extending into inner half of the enamel but
not to amelo-dentineal junction– D3 = caries limited to the outer half of the dentine– D4 = caries involving the inner half of the dentine
Histologic examination
Nyvad’s system
특징 )
1. 병변의 activity 는 치아표면에 형성된 plaque 의 질감 , 색에 근거하여 판단
2. Descriptive method
Specific criteria 없이 판단하는 방법
ICDAS 와 Nyvad’s system 의 비교
1. 두 개의 System 모두에서 재현성이 좋음
2. ICDAS system 의 경우 enamel 병소를 두 단계로 나누기 때문에 조직학적 특성과 좀 더 일치한다 .
