评估了牙本质脱敏剂 Systemp 对使用三种不同粘合剂（即 Prime & Bond NT、Xeno V+ 和 Futurabond DC）的复合树脂与牙本质的剪切粘合强度的影响。六十颗最近拔出的人类前磨牙被分为六组，每组十颗牙齿。用37%磷酸酸蚀表层牙本质。在第一组、第二组和第三组中，分别将 Prime & Bond NT、Xeno V+ 和 Futurabond DC 应用于牙本质和复合材料放置。在 IV、V 和 VI 组中应用牙本质脱敏剂 Systemp 后，分别将 Prime & Bond NT、Xeno V+ 和 Futurabond DC 应用于牙本质和复合材料放置。评价剪切粘合强度。使用单向方差分析、事后分析和 Dunnett 检验对获得的数据进行统计分析。使用牙本质脱敏剂 Systemp 后，使用 Prime & Bond NT 粘接剂时平均剪切粘接强度增加，而使用 Xeno V+ 和 Futurabond DC 粘接剂时平均剪切粘接强度下降。在该体外研究的限制内，观察到在应用牙本质脱敏剂 Systemp 后，平均剪切粘合强度可能会增加或减少，具体取决于所使用的粘合剂。
The effect of dentin desensitizer Systemp on the shear bond strength of composite resin to dentin using three different bonding agents, i.e., Prime & Bond NT, Xeno V+, and Futurabond DC were evaluated. Sixty recently extracted human premolars were divided into six groups of ten teeth each. The superficial dentin was etched with 37% phosphoric acid. In Groups I, II, and III, Prime & Bond NT, Xeno V+, and Futurabond DC, respectively, were applied to dentin and composite placed. Following application of dentin desensitizer Systemp in Groups IV, V, and VI, Prime & Bond NT, Xeno V+, and Futurabond DC, respectively, were applied to dentin and composite placed. The shear bond strength was evaluated. Data obtained were statistically analyzed using one-way analysis of variance, post hoc, and Dunnett's test. Following application of dentin desensitizer Systemp, mean shear bond strength increased when Prime & Bond NT bonding agent was used while it decreased for Xeno V+ and Futurabond DC bonding agents. Within the limitations of this in vitro study, it was observed that following application of dentin desensitizer Systemp, mean shear bond strength may increase or decrease depending on the bonding agents used.
