The aims of this study were to develop an automatic detection technique for tooth cracks and to suggest quantitative methods for measuring gingival sulcus depth using swept-source optical coherence tomography (SS-OCT). We evaluated SS-OCT with wavelength centered at 1310 nm over a spectral bandwidth of 100 nm at a rate of 50 kHz as a new diagnostic tool for the detection of tooth cracks and gingival sulcus depth. The reliability of the SS-OCT images was verified by imaging the crack in extracted human teeth and gingival sulcus of porcine sample. The SS-OCT could automatically detect the position of various cracks and visualize the deep periodontal pockets. Therefore, the detection capability of SS-OCT images could be useful diagnostic tool for dental cracks and periodontal pockets.
本研究的目的是开发一种用于检测牙齿裂纹的自动检测技术，并提出使用扫频源光学相干断层扫描（SS-OCT）测量牙龈沟深度的定量方法。我们评估了中心波长为1310 nm、光谱带宽为100 nm、速率为50 kHz的SS-OCT，将其作为检测牙齿裂纹和牙龈沟深度的一种新型诊断工具。通过对拔除的人牙裂纹和猪样本牙龈沟进行成像，验证了SS-OCT图像的可靠性。SS-OCT能够自动检测各种裂纹的位置，并可视化深部牙周袋。因此，SS-OCT图像的检测能力可成为诊断牙齿裂纹和牙周袋的有用工具。
