摘要

我们提出了一种牙釉质拔罐损伤形成的新理论。在早期，自然形成的火罐病变在两个棱柱状结构特征上表现出孔隙度增加，即延伸到牙釉质-牙本质连接处的中央锥体和1型hunter - schreger带(HSB)，这表明它们是火罐病变形成和发展的主要驱动力。此外，这些损伤由ii型hsb限定，具有较低的表面孔隙率和较高的耐磨性。这一理论在体外观察中得到了验证，在体外观察中，尖牙釉质的中央锥体和i型HSB都表现出更高的磨损敏感性，这可能阐明了拔罐损伤形成的机制。

New Theory Illustrates the Formation of Enamel CUP-Shaped Lesions on Occlusal Surfaces.

We propose a new theory for enamel cupping lesions formation. At early stages, naturally formed cupping lesions showed increased porosity at two structural prismatic traits: the central cone extending into the enamel-dentine junction and the type-I Hunther-Schreger bands (HSB), suggesting them to be the main drivers for cupping lesion formation and development. In addition, these lesions were circumscribed by type-II HSBs, which present lower surface porosity and higher resistance to wear. This theory was verified in in vitro observations, where both the central cone and the type-I HSB of cuspal enamel showed higher susceptibility to wear, potentially elucidating the mechanisms involved on cupping lesion formation.

期刊介绍： ''Caries Research'' publishes epidemiological, clinical and laboratory studies in dental caries, erosion and related dental diseases. Some studies build on the considerable advances already made in caries prevention, e.g. through fluoride application. Some aim to improve understanding of the increasingly important problem of dental erosion and the associated tooth wear process. Others monitor the changing pattern of caries in different populations, explore improved methods of diagnosis or evaluate methods of prevention or treatment. The broad coverage of current research has given the journal an international reputation as an indispensable source for both basic scientists and clinicians engaged in understanding, investigating and preventing dental disease.
