Studies by optical microscopy, microradiography and SEM suggested that sclerosis is the result of occlusion of the dentinal tubules by a mineral substance with a refractive index similar to that of the rest of the dentine. Translucence appeared before the majority of the tubules were completely occluded. The deposition of the occluding mineral took place initially in individual tubules or in groups of tubules. The occluding material and the peritubular dentine were almost indistinguishable under SEM. Both were smooth and densely mineralized. The process of deposition of occluding mineral appeared to be more like that of in-vitro mineralization and thus different from that of peritubular dentine.
光学显微镜、显微放射摄影术和扫描电子显微镜的研究表明，硬化是由于一种折射率与其余牙本质相似的矿物质堵塞牙本质小管所致。在大多数小管完全堵塞之前就出现了半透明现象。堵塞性矿物质的沉积最初发生在单个小管或成组的小管中。在扫描电子显微镜下，堵塞物质和管周牙本质几乎无法区分。两者都很光滑且矿化密集。堵塞性矿物质的沉积过程似乎更类似于体外矿化过程，因此不同于管周牙本质的沉积过程。
