自蚀刻底漆被认为比全蚀刻胶粘剂系统具有显著的优势。本研究检验的假设是，在相同ph下，自蚀刻底漆和磷酸溶液之间的蚀刻特性没有差异。蚀刻使用原子力显微镜（AFM）评估小管周围和管间牙本质高度随暴露时间的特定位置变化。用耐酸玻璃参考层制备的人牙本质盘（n=6/组），用自蚀刻底漆和0.0134m磷酸（pH均为1.94）蚀刻。在每个蚀刻间隔后，在15个不同的位置，分别在小管周围和管间的牙本质上，用AFM测量相对于参考层的深度变化。用扫描电镜测定了总脱矿深度。可测量的管周牙本质腐蚀速率为线性（可达15秒），自腐蚀引物的腐蚀速率更高（p<0.0001）。管间牙本质在两种酸的作用下表现出相似的脱矿模式，在大多数标本中最终达到平台。与磷酸相比，自蚀刻引物在衰退后达到平稳期（p<0.0001）。除腐蚀剂溶液的pH值外，牙本质脱矿似乎还受其他因素的影响。
Self-etching primers are thought to offer significant advantages over total-etch adhesive systems. The hypothesis tested in this study was that there was no difference in etching characteristics between a self-etching primer and a phosphoric acid solution at the same pH. Etching was assessed using atomic force microscopy (AFM) evaluation of site-specific changes in the height of the peritubular and intertubular dentin as a function of exposure time. Human dentin disks (n=6/group), prepared with an acid-resistant glass reference layer, were etched with a self-etching primer and with 0.0134m phosphoric acid (both pH≅1.94). Depth changes relative to the reference layer were measured with the AFM after each etching interval, at 15 different locations, each in the peritubular and intertubular dentin. The total demineralization depth was measured in a scanning electron microscope. Peritubular dentin etching rate was linear while it could be measured (up to 15s) and was greater for the self-etching primer (p<0.0001). Intertubular dentin displayed a similar demineralization pattern with both acids, ultimately reaching a plateau in the majority of specimens. The self-etching primer attained a plateau after less recession than phosphoric acid (p<0.0001). Dentin demineralization appears to be affected by other factors in addition to the pH of the etchant solutions.
