This article deals with the autofluorescence spectra from the hard tissues of a tooth, both in norm and pathology. An investigation was made on 30 extracted human teeth. The measurements were made both for the intact hard tissues of a tooth, such as enamel, dentine, cementum, and root canal, and for the tissues pathologically affected by a caries (superficial, intermediate, and deep) and by a dental calculus. It was found that the fluorescent spectra from enamel, dentine, cementum, and from the regions affected by a caries and dental calculus were identical in form. All the spectra revealed a maximum near 700 nm. However, the intact and affected hard tissues were greatly different in the integral fluorescent intensity. Dental calculus was found to produce the most pronounced fluorescent intensity, whereas the carious regions produced a slightly weaker fluorescent intensity. On the contrary, the intact hard tissues of a tooth exhibited the poorest fluorescent intensity.
本文探讨了正常和病理状态下牙齿硬组织的自体荧光光谱。对30颗拔除的人类牙齿进行了研究。对牙齿的完整硬组织，如牙釉质、牙本质、牙骨质和根管，以及受龋齿（浅龋、中龋和深龋）和牙结石病理影响的组织都进行了测量。结果发现，牙釉质、牙本质、牙骨质以及受龋齿和牙结石影响区域的荧光光谱在形式上是相同的。所有光谱在700 nm附近都有一个最大值。然而，完整和受影响的硬组织在积分荧光强度上有很大差异。发现牙结石产生的荧光强度最明显，而龋损区域产生的荧光强度稍弱。相反，牙齿的完整硬组织表现出最差的荧光强度。
