구강 내에 존재하는 치아의 표면은 항상 탈회와 재광화의 가역적인 반응이 일어나고 있다. 이러한 동적과정에 불균형이 생기게 되면 우리가 잘 아는 치아우식증으로 진행하게 된다. 즉 치아우식증은 넓게 보면 법랑질 표면에서 발생한 미세한 구조의 파괴를 시작으로 해서 법랑질, 상아질로 진행하여 와동을 형성(cavitation)하는 과정까지 연속적으로 길게 이어져있다. 임상적으로는 와동이 형성되고 불소와 같은 재광화 물질로는 원상회복이 되지 않으며 현저한 구조의 파괴가 일어나는 시점을 치아우식증이라고 정의할 수 있으나, 지금부터 우리가 관심을 가지고 관찰하여야 할 현상은 바로 와동 형성단계 이전의 초기우식증이다.
The detection of carious lesions is a key point to apply appropriate preventive measures or operative treatment of dental caries. A laser fluorescence device DIAGNOdent® (KaVo, Biberach, Germany) has also been shown to be of additional clinical value in the detection of initial caries. This report focus on the DIAGNOdent® for caries detection. DIAGNOdent® irradiate visible red light at a wavelength of 655 nm to elicit near-infrared fluorescence from caries lesion. This device is known as a reproducible method for caries detection, with good sensitivity and specificity especially for caries detection on occlusal and accessible smooth surfaces. DIAGNOdent® tended to be more sensitive method of detecting occlusal dentinal caries, however, showed more false-positive diagnoses than the visual inspection. So Clinician should not use the device as a clinician’s primary diagnostic method and it is recommended that the device should be used in the decision-making process in relation to the diagnosis of caries as a second opinion in cases of doubt after visual inspection. The trend of modern dentistry would be a preventive approach rather than invasive treatment of the disease. This is possible only with early detection and respective preventive measures, DIAGNOdent® can help the changes.
