This study investigated the effect of an aluminum chloride hemostatic agent on the shear bond strength (SBS) of a universal adhesive to dentin.
Eighty extracted human molars were trimmed at the occlusal dentin surfaces and divided mesiodistally. According to hemostatic agent application, specimens were randomly allocated into control (C) and hemostatic agent (Traxodent; H) groups. Each group was divided into 4 subgroups according to the adhesive system ( = 20): Scotchbond Multi-Purpose (SBER), Clearfil SE Bond (CLSE), All-Bond Universal etch-and-rinse mode (ALER), and All-Bond Universal self-etch mode (ALSE). SBS was measured for half of the specimens at 24 hours, and the other half were thermocycled in water baths (group T). Fracture surfaces were examined to determine the failure mode. The SBS was measured, and data were analyzed using 1-way analysis of variance, the Student's -test, and the Tukey honestly significant difference test ( = 0.05).
No significant differences in SBS were found between groups C and H for any adhesive system at 24 hours. After thermocycling, a statistically significant difference was observed between CT+ALSE and HT+ALSE ( < 0.05). When All-Bond Universal was applied to hemostatic agent-contaminated dentin, the SBS of H+ALSE was significantly lower than that of H+ALER ( < 0.05). The SBER subgroups showed no significant differences in SBS regardless of treatment and thermocycling.
When exposed dentin was contaminated by an aluminum chloride hemostatic agent before dentin adhesive treatment, application of All-Bond Universal in etch-and-rinse mode was superior to self-etch mode.
本研究调查了一种氯化铝止血剂对通用型粘结剂与牙本质之间剪切粘结强度（SBS）的影响。
80颗拔除的人磨牙在咬合面牙本质表面进行修整，并沿近远中方向分割。根据止血剂的应用情况，将标本随机分为对照组（C）和止血剂组（Traxodent；H）。每组根据粘结系统分为4个亚组（每组n = 20）：Scotchbond多功能粘结剂（SBER）、Clearfil SE粘结剂（CLSE）、全粘结通用型酸蚀冲洗模式（ALER）和全粘结通用型自酸蚀模式（ALSE）。对一半标本在24小时时测量SBS，另一半在水浴中进行热循环处理（T组）。检查断裂面以确定失效模式。测量SBS，并使用单因素方差分析、Student's t检验和Tukey真实显著性差异检验（α = 0.05）对数据进行分析。
在24小时时，对于任何粘结系统，C组和H组之间的SBS均无显著差异。热循环后，CT + ALSE组和HT + ALSE组之间观察到统计学上的显著差异（P < 0.05）。当全粘结通用型粘结剂应用于被止血剂污染的牙本质时，H + ALSE组的SBS显著低于H + ALER组（P < 0.05）。无论是否进行处理和热循环，SBER亚组的SBS均无显著差异。
在牙本质粘结处理前，当暴露的牙本质被氯化铝止血剂污染时，采用酸蚀冲洗模式应用全粘结通用型粘结剂优于自酸蚀模式。
