Abstract:
There is an increasing need in dental research and clinical practice for accurate measurements of teeth. Currently, methods such as x-rays and quantitative light-induced fluorescence (QLF) are used, but there are problems such as the effects of radiation and limitations in resolution. Optical Coherence Tomography (OCT) used in this study uses near-infrared light, which has no effect on the human body and provides very high resolution in the range of tens of micrometers. OCT allows for non-invasive imaging, making it safer for repeated use and ideal for monitoring caries progression over time. In this study, we developed a portable OCT scanner specialized for dental use and measured and evaluated early caries and demineralization.
