脱矿的根牙本质和牙骨质主要是胶原蛋白，在脱水时显著收缩。活动性根龋病变在脱水时表现出收缩，然而在根龋病变的再矿化过程中，矿物质沉积在病变的外部，阻止病变，并且阻止的病变在脱水时不再表现出收缩。光学相干断层扫描非常适合测量这种收缩，以评估病变活动性。在这项研究中，使用CP-OCT系统测量了拔牙上自然根龋病变的收缩，该系统具有适合临床使用的3D打印器具，该器具具有集成的空气喷嘴。
Demineralized root dentin and cementum are mostly collagen that shrinks significantly upon dehydration. Active root caries lesions manifest shrinkage upon dehydration, however during the remineralization of root caries lesions mineral is deposited on the outside of the lesion arresting the lesion and arrested lesions no longer manifest shrinkage upon dehydration. Optical coherence tomography is ideally suited for the measurement of that shrinkage for the assessment of lesion activity. In this study the shrinkage of natural root caries lesions on extracted teeth were measured using a CP-OCT system with a 3D printed appliance with an integrated air nozzle suitable for clinical use.
