In-vitro caries diagnostic study - 375 bitewing radiographs of extracted human teeth

The aim of the research project was to test the validity and reliability of new methods of caries diagnostics on extracted human molars in vitro. A total of 375 teeth were examined. Microtomographic images were taken as a reference standard. Radiographs of these teeth and white light images from the occlusal, proximal, buccal and oral directions were taken as a comparative imaging technique to the new methods. As new examination methods, tranisillumination images were taken from the occlusal direction using near-infrared light with wavelengths of 1050, 1200 and 1300 nm with two different indium gallium arsenide (InGaAs) cameras. On the other hand, reflection images of the occlusal, buccal and oral areas were taken using near-infrared light with wavelengths of 1050, 1200, 1300 and 1550 nm, also with two InGaAs cameras. The cameras differed in the size of their sensor, with 320x256 and 640x512 pixels respectively. This is the bitewing X-ray data set of the 375 teeth.

本研究项目旨在体外验证离体人类磨牙龋病诊断新方法的有效性与可靠性。共计纳入375颗牙齿开展检测。以显微断层扫描（microtomographic）图像作为金标准参考。将上述牙齿的X线片，以及从咬合面、邻面、颊面和口腔侧采集的白光图像作为对照成像手段，与新型诊断方法进行性能对比。
本次研究采用的新型检测方案分为两类：其一，使用两台参数不同的铟镓砷（Indium Gallium Arsenide, InGaAs）相机，以波长为1050、1200和1300 nm的近红外光，从咬合面方向拍摄近红外透照（transillumination）图像；其二，同样搭载两台InGaAs相机，以波长为1050、1200、1300和1550 nm的近红外光，拍摄咬合面、颊面及口腔侧区域的近红外反射图像。两款相机的传感器像素尺寸存在差异，分别为320×256与640×512。本数据集为上述375颗牙齿的咬翼X线数据集。
