Dentine carious lesions can be remineralized under optimal conditions, while the surface characteristics of the caries-attacked area may play an important role in the remineralization process. To understand such a surface mechanism, we examined the microstructures of the remineralized area pretreated with different methods. It was found that dentinal tubules on the remineralized surface orientated differently from intrinsic dentine tubules, with the specific alignment angle determined by different surface treatments. Various surface treatments included in this study were 37% phosphoric acid treatment (the etched group), 37% phosphoric acid etching followed by the application of 10% sodium hypochlorite treatment (the deproteinized group), and untreatment (the control group). These findings are helpful for understanding the non-restorative repair of dentine lesions and the remineralization process of the caries-affected dentin surface.
在最佳条件下，牙本质龋损可以再矿化，而龋损区域的表面特征可能在再矿化过程中起重要作用。为了了解这种表面机制，我们研究了用不同方法预处理后的再矿化区域的微观结构。结果发现，再矿化表面的牙本质小管与固有牙本质小管的方向不同，具体的取向角度由不同的表面处理决定。本研究中包含的各种表面处理方法包括 37%磷酸处理（酸蚀组）、37%磷酸酸蚀后应用 10%次氯酸钠处理（脱蛋白组）和未处理（对照组）。这些发现有助于理解牙本质病变的非修复性修复和受龋影响的牙本质表面的再矿化过程。
