Abstract

Tensile bond strengths between dentin and a typical restorative resin were measured after the dentin was treated with Gluma. Solutions of phosphoric, pyruvic, nitric, or oxalic acid, also containing various amino acids, were used as pretreatments. Without amino acids in the solutions, the pretreatments conferred bonds of low strength. Use of acidic solutions containing glycine or N-phenylglycine was found to give bonds of high strength to both dentin and enamel.

摘要

用Gluma处理牙本质后，测量牙本质与一种典型修复性树脂之间的拉伸粘结强度。磷酸、丙酮酸、硝酸或草酸溶液（也含有各种氨基酸）用作预处理。溶液中不含氨基酸时，预处理产生的粘结强度较低。发现使用含有甘氨酸或N-苯基甘氨酸的酸性溶液可使牙本质和牙釉质都获得高强度粘结。
