The rate of deterioration of pyruvic acid/glycine solutions used as common pretreatment of enamel and dentin in the Gluma bonding technique was investigated. Bond strengths between composite resin and enamel/dentin were measured. The bonds were mediated by pyruvic acid/glycine solutions, applied from 0 to 6 months after the time of manufacture. Bond strengths to enamel varied between 8.6 and 13.5 MPa and to dentin between 6.2 and 18.0 MPa. The pH of the solutions rose slightly during the experimental period, but no statistically significant change in bond strengths was observed.
研究了在Gluma粘结技术中用作牙釉质和牙本质常规预处理的丙酮酸/甘氨酸溶液的变质速率。测量了复合树脂与牙釉质/牙本质之间的粘结强度。粘结由丙酮酸/甘氨酸溶液介导，在制造后的0至6个月内使用。与牙釉质的粘结强度在8.6至13.5MPa之间，与牙本质的粘结强度在6.2至18.0MPa之间。在实验期间，溶液的pH值略有上升，但未观察到粘结强度有统计学上的显著变化。
