초록

Hidden caries는 임상 검사상 교합면이 매우 건전하거나 소량의 탈회만이 관찰되지만 방사선 사진 상에서 상당 수준 진행된 상아질 우식이 발견되는 경우를 일컬으며 Covert caries, Occult caries, Fluoride syndrome 등이 동의어로 사용되고 있다. 발생 원인으로는 불소의 영향, 세균의 종류 및 세균 영양분 공급 경로의 차이, 열구 기저면으로부터 시작된 우식증, 맹출 전우식증 등의 주장들이 제기되고 있지만 현재 정확한 원인은 밝혀지고 있지 않다. 본 증례는 임상 및 방사선 사진 검사에서 Hidden caries를 발견한 두 환아들의 치험례로 두 증례 모두에서 깊은 상아질 우식을 보여 각각 치근단 형성술과 간접치수복조술을 시행하였다. 교합면이 비교적 건전해 보이는 특징 뿐만 아니라 Hidden caries의 우식 상아질은 임상적으로 관찰 가능한 우식에서 채취한 우식 상아질에 비해 밝은 색을 띄는 특징이 있어 시진으로 관찰하기 더욱 어려운 것으로 생각된다. 따라서 본 증례와 같이 진행된 우식병소로 인해 임상증상이 발현된 후에야 이를 발견하게 되는 경우가 많으므로 정기적인 방사선 검사와 함께 Diagnodent.. 등과 같은 최신의 우식 진단도구들의 사용으로 우식병소의 조기진단을 위해 노력해야 할 것으로 생각된다.

Hidden caries is a subtype of the occlusal pit and fissure caries type and is defined as a dentinal caries lesion near the occlusal surface of the tooth seen on a radiograph. In visual examination, the occlusal enamel is seen intact or is minimally perforated. Covert caries, Occlult caries or Fluoride syndrome are used as synonym. The percentage of occlusal dentin lesions that are clinically undetected ranges from 1.4-50%. Little is known about the mechanisms involved in the development of hidden caries. But it is thought that extensive use of topical fluoride or the special bacteriological profile has been a major factor. This case report is about detection and treatment of hidden caries of two children who visited the department of pediatric dentistry, Yonsei University Dental Hospital. The color of caries dentin found in hidden caries lesion is lighter than cavity forming caries, which makes it more difficult to detect caries by visual examination. Therefore diagnosis of hidden caries is often accomplished after clinical sign is recognized by patients. The use of advanced caries detection aids such as Diagnodent.. with periodic radiographic examination is seemed to be helpful for early detection of hidden caries.
