（H， PO,）是一种被广泛接受和应用的技术，用于改善牙科树脂与牙釉质的结合，在修复牙科中，“在预防性牙科中”，以及用于正畸附着物的直接结合。建议临床使用的浓度范围为30%至60%。为了确定作为珐琅蚀刻剂的H、PO的最佳浓度，进行了大量的研究。牙修复树脂与不同浓度的H、PO蚀刻牙釉质表面的拉伸结合强度研究已用于此目的。这些研究者推荐的最佳H， PO浓度范围为8%至65%。本研究旨在通过拉伸粘结强度试验确定H、PO作为牙釉质蚀刻剂的最佳浓度。
(H, PO,) is an accepted and widely applied technique to improve bonding of dental resins to enamel in restorative dentistry,’in preventive dentistry,’and for the direct bonding of orthodontic attachments. 3 The concentrations recommended for clinical use range from 30% to 60%. Numerous investigations have been carried out to define the optimal concentration of H, PO, for use as an enamel etching agent. Tensile bond strength studies of dental restorative resins to enamel surfaces etched with different concentrations of H, PO, have been used for this purpose. 4-‘5 The optimal concentrations of H, PO, recommended by these investigators have ranged from 8% to 65%. This study was designed to determine an optimal concentration of H, PO, as an enamel etching agent by means of tensile bond strength tests.
