The aim of this study was to evaluate the shear bond strength of metal brackets bonded with different universal adhesive systems containing 10-MDP and Transbond Plus Self Etching Primer after 20,000 thermal cycles. . A total of 130 sound bovine teeth were used, which are divided into 5 groups ( = 26) according to the adhesive system used: All-Bond Universal (Bisco), Ambar Universal (FGM), Clearfil Universal Bond (Kuraray), Single Bond Universal (3M/ESPE), and Transbond Plus SEP (3M/ESPE) as control. The adhesives were applied for 20 seconds and bonded with a resin Transbond XT (3M/ESPE). After this, the teeth were submitted to 20,000 cycles at 5°C and 55°C. Afterwards, the shear bond strength test was performed in a universal test machine (Instron 3342). The adhesive remnant index (ARI) was evaluated under a stereomicroscope at 10x magnification and scanning electronic microscopy (SEM, Hitachi 3030). The shear bond strength data were submitted to One-Way ANOVA ( = 0.05) and the ARI to the Kruskal-Wallis test ( = 0.05) and the ARI to the Kruskal-Wallis test (.
Statistical analysis showed that the universal adhesive systems presented mean shear bond strength values similar to Transbond Plus SEP ( < 0.05). The universal adhesive presented similar ARI values among them but differed from those of Transbond Plus SEP ( < 0.05). The universal adhesive presented similar ARI values among them but differed from those of Transbond Plus SEP (.
The results show that universal adhesive systems may be used for bonding metal brackets if the orthodontist wants to maintain dental enamel health.
本研究的目的是评估在经过20000次热循环后，使用含10 - MDP的不同通用粘结系统和Transbond Plus自酸蚀底漆粘结的金属托槽的剪切粘结强度。总共使用了130颗完好的牛牙，根据所使用的粘结系统分为5组（每组 = 26颗）：全粘结通用型（Bisco）、安巴尔通用型（FGM）、可乐丽菲露通用粘结剂（可乐丽）、单组分通用粘结剂（3M/ESPE），以及作为对照的Transbond Plus SEP（3M/ESPE）。将粘结剂涂抹20秒，并用树脂Transbond XT（3M/ESPE）进行粘结。在此之后，牙齿在5°C和55°C下进行20000次循环。之后，在万能试验机（Instron 3342）上进行剪切粘结强度测试。在体视显微镜下以10倍放大倍数以及扫描电子显微镜（SEM，日立3030）下评估粘结剂残留指数（ARI）。将剪切粘结强度数据进行单因素方差分析（α = 0.05），ARI数据进行克鲁斯卡尔 - 沃利斯检验（α = 0.05）。
统计分析表明，通用粘结系统呈现出与Transbond Plus SEP相似的平均剪切粘结强度值（P < 0.05）。通用粘结剂之间呈现出相似的ARI值，但与Transbond Plus SEP的ARI值不同（P < 0.05）。通用粘结剂之间呈现出相似的ARI值，但与Transbond Plus SEP的ARI值不同（P < 0.05）。
结果表明，如果正畸医生想要保持牙釉质健康，通用粘结系统可用于粘结金属托槽。
