我们考察了温风干燥对三种单步自酸蚀粘接剂的釉质粘结强度和表面自由能的影响。将牛下颌切牙固定在自固化树脂中，然后用#600碳化硅(碳化硅)纸湿磨。粘合剂按照各自制造商的说明涂布，然后在常温(23°C)或暖(37°C)气流中干燥5、10和20℃，直至S。在可见光照射下，树脂复合材料凝聚到模具中并聚合。每组10个样品在37°C的蒸馏水中储存24小时，然后测量粘结强度。通过测量放置在固化胶粘剂上的三种测试液体的接触角来确定表面自由能。牙釉质粘结强度随风干时间的不同而不同，变化范围为15.8~19.1 Mpa。不同材料的粘结强度变化趋势不同。用暖风干燥时，组分的值略有增加，而组分的值显著下降。这些数据表明，温风干燥对于获得足够的牙釉质粘结强度是必不可少的，尽管增加干燥时间对粘结强度没有显著影响。
We examined the effect of warm air‐drying on the enamel bond strengths and the surface free‐energy of three single‐step self‐etch adhesives. Bovine mandibular incisors were mounted in self‐curing resin and then wet ground with #600 silicon carbide (SiC) paper. The adhesives were applied according to the instructions of the respective manufacturers and then dried in a stream of normal (23°C) or warm (37°C) air for 5, 10, and 20 s. After visible‐light irradiation of the adhesives, resin composites were condensed into a mold and polymerized. Ten samples per test group were stored in distilled water at 37°C for 24 h and then the bond strengths were measured. The surface free‐energies were determined by measuring the contact angles of three test liquids placed on the cured adhesives. The enamel bond strengths varied according to the air‐drying time and ranged from 15.8 to 19.1 MPa. The trends for the bond strengths were different among the materials. The value of the component increased slightly when drying was performed with a stream of warm air, whereas that of the component decreased significantly. These data suggest that warm air‐drying is essential to obtain adequate enamel bond strengths, although increasing the drying time did not significantly influence the bond strength.
