人类口腔中可能出现多种牙齿疾病，从牙周炎等骨骼疾病或由大规模感染引起的骨质流失，到蛀牙等常见问题。我们使用光学相干断层扫描（OCT）与放射学检查的金标准探讨了牙齿（及相关骨骼）状况的可能范围[Erdelyi r.a., Duma v.f。[j].材料工程，2016,(1):1 - 4。临床和影像学调查已经在现实生活中的病人身上进行了。基于OCT比x线摄影具有更好的分辨率（分别为2 ~ 10 μm和75 ~ 150 μm），而x线摄影可以提供整个口腔的完整图像，而OCT在牙齿或软组织中的穿透力有限，仅为1 ~ 2mm，推断了使用这两种成像技术的优点和局限性。通过对一系列牙齿状况的分析，这两种技术澄清了何时更适合选择一种特定的方法：(i)对于骨骼疾病，x光片更合适，因为它们在一次曝光中提供整个口腔的图像和牙齿状况的3D图像；（ii） OCT能在早期发现小蛀牙，而x光片不能；（iii）对两种成像技术发现的空腔进行的测量证明，OCT可以提供准确的尺寸，具有高对比度和高噪比。因此，对于每种可能的牙齿状况，两种类型的成像技术中的每一种进行了分类。总结了OCT和x线摄影在牙科调查中的互补作用。
There are numerous dental conditions that can appear in the human mouth, from bone diseases like periodontitis or bone loss produced by a massive infection, to common issues like dental cavities. We explored the possible range of dental (and associated bone) conditions using Optical Coherence Tomography (OCT) versus the gold standard of radiological investigations [Erdelyi R.A., Duma V.-F., et al, Materials 13, 4825, 2020]. Clinical and imaging investigations have been performed on real-life patients. Advantages and limitations of using these two imaging techniques were deduced, based on the fact that OCT has better resolution than radiographs (2 to 10 μm versus 75 to 150 μm, respectively), while radiography can perform a complete image of the entire mouth, in contrast to OCT, which has a limited penetration, of only 1 to 2 mm in tooth or soft tissue. The analyses of a range of dental conditions with both techniques clarified when it is better to choose a specific method: (i) for bone diseases, radiographs are more appropriate because they provide images of the entire mouth in one exposure and 3D images of dental conditions; (ii) OCT can spot small cavities in early stages, while radiographs cannot; (iii) measurements performed on cavities spotted with both imaging techniques proved that OCT can provide accurate dimensions, with high contrast and contrast-to-noise ratio. Thus, a classification of each of the two types of imaging techniques for each possible dental condition was obtained. A complementarity of OCT and radiography for investigations in dentistry was concluded.
