需要新的成像方法来评估牙齿表面龋齿病变的活动性。最近的研究表明，在用空气脱水期间，牙根表面上的损伤的热成像可用于确定损伤是活跃的还是被阻止的。在这项研究中，使用带有微型热成像仪的成像系统和带有适合临床使用的集成空气喷嘴的3D打印手机，监测了在空气脱水过程中拔牙根龋病变的热发射变化。本研究评估了热成像相机的性能，用于成像根龋的提取牙齿之前，它的使用在体内研究。在恒定气流条件下，人牙齿在干燥状态下的热反应与正常牙根区的热反应有显著差异。
New imaging methods are needed to assess the activity of caries lesions on tooth surfaces. Recent studies have shown that thermal imaging of lesions on root surfaces during dehydration with air can be used to determine if the lesions are active or arrested. In this study changes in the thermal emission of root caries lesions on extracted teeth during dehydration with air was monitored using an imaging system with a miniature thermal camera and a 3D printed handpiece with an integrated air nozzle suitable for clinical use. This study evaluated the performance of the thermal camera for imaging root caries on extracted teeth prior to it's use for in vivo studies. There was a significant difference in the thermal response of sound and root lesion areas of human teeth under dehydration at constant airflow.
