This in vitro study examined the effects of three different types of acid etchants on the bond strengths of three dentin bonding systems. The etchant free of both silica and oxalate provided the highest bond strengths for all three systems. Use of the etchant containing oxalate resulted on the lowest bond strengths for all three systems. It is suggested that bond strengths vary as a consequence of deposition onto the dentin surface of various minerals or salts found in the etchants. It is recommended that if treatment of dentin with acids is indicated it should probably be done with those etchants containing neither silica nor oxalate.
这项体外研究考察了三种不同类型的酸蚀剂对三种牙本质粘结系统粘结强度的影响。不含二氧化硅和草酸盐的蚀剂为所有三种系统提供了最高的粘结强度。使用含草酸盐的蚀剂导致所有三种系统的粘结强度最低。据推测，粘结强度的变化是由于蚀剂中发现的各种矿物质或盐类沉积在牙本质表面所致。建议如果需要用酸处理牙本质，可能应该使用既不含二氧化硅也不含草酸盐的蚀剂。
