早期发现龋损病变并进行及时正确地干预可以逆转龋病的进程,最大限度地保存牙齿,减少创伤性治疗;因此,龋病的早期准确诊断就显得非常重要。目前,临床上使用的常规检测龋病的方法无法客观、有效地检测早期龋,更不能对龋损进程进行定量监测,这就往往使患者丧失了保守治疗的最佳时机;因此,迫切需要安全、准确、可量化的技术来检测早期龋并对治疗干预措施进行监控。近年已开发出一系列检测早期龋的无创、定量检测新技术,本文就光学相干层析技术(OCT)用于检测早期光滑面釉质龋、早期牙骨质龋、早期窝沟龋等方面的研究作一综述。 Early detection of carious lesion and timely and correct intervention can reverse the progress of caries, maximize the preservation of teeth, reduce traumatic treatment; therefore, early diagnosis of caries is very important. At present, the routine methods for detecting caries used clinically can not objectively and effectively detect early caries, and moreover, it is impossible to monitor the progress of caries progressively, which often results in patients losing the optimal opportunity for conservative treatment. Therefore, there is an urgent need for safety , Accurate, quantifiable techniques to detect early caries and monitor therapeutic interventions. In recent years, a series of new noninvasive and quantitative detection methods for detecting early caries have been developed. In this paper, optical coherence tomography (OCT) is used to study the early smooth surface enamel caries, early cementum caries and early pit and fossa caries Make a review
