本研究的目的是开发一种临床短波红外反射手机，以评估活动的病变的咬合面。在强制空气干燥期间，使用台式系统和改进的临床原型在1470 nm处监测离体牙齿上10个活动性和10个停止的咬合面龋齿病变的时间分辨反射率。使用显微计算机断层扫描（microCT）测量的高度矿化表面层的存在来指示病变活动。从获得的SWIR时间与强度脱水曲线中提取多个动力学参数，并用于评估病变活动。三个参数：从SWIR脱水曲线计算的延迟、%Ifin和速率在活动性和停滞损伤之间有显著差异（p< 0.05）。改良后的临床探针能在30 s内完全显示窝沟内的所有活动性病变区域。
The aim of this study was to develop a clinical SWIR reflectance handpiece to assess the activity of lesions on the occlusal surfaces. The time‐resolved reflectivity of 10 active and 10 arrested occlusal caries lesions on extracted teeth was monitored at 1470 nm using a benchtop system and a modified clinical prototype during forced air drying. The presence of a highly mineralized surface layer measured with microcomputed tomography (microCT) was used to indicate lesion activity. Multiple kinetic parameters were extracted from the acquired SWIR time versus intensity dehydration curves and used to assess lesion activity. Three parameters: delay, %Ifin, and rate calculated from the SWIR dehydration curves were significantly different (p< 0.05) between active and arrested lesions. The modified clinical probe was able to completely dehydrate all the active lesion areas in the occlusal pits and fissures in less than 30 s.
