To study aimed to evaluate the influence of infiltrated alkaline biomaterials on the bond strength of composite obtained with etch and rinse and universal adhesive systems. Coronal dentin of extracted human molars was exposed and infiltrated with calcium hydroxide, MTA, or bioactive glass 45S5 powder. Non‐infiltrated dentin specimens served as controls. Subsequently, dentin was either acid‐etched or not, and remaining alkali content was measured by pH induction in water. Shear bond strength of an etch‐and rinse system (Adper Single Bond 2) on etched dentin was then compared to that of a universal counterpart (Single Bond [(Scotchbond) Universal] by the same manufacturer. Data was compared between groups using one‐way ANOVA and Tukey's HSD. On sound dentin, the etch‐and‐rinse system adhered stronger than the universal system (p < .05). All particles rendered the dentin alkaline. Acid etching reduced the alkali content in the infiltrated dentin. However, bond strength values were stronger with the universal system without etching than with the etch‐and rinse counterpart, which lost more than 60% of its adhesiveness. The universal adhesive system was less susceptible to alkaline contamination of the dentin than the etch‐and‐rinse counterpart. Based on the similar composition of the two systems under investigation, this is likely to the due to its 10‐MDP component.

牙本质中颗粒状碱性生物材料残留物对两种树脂基粘接系统粘附的影响
研究旨在评估渗透的碱性生物材料对使用蚀刻和冲洗以及通用粘合剂系统获得的复合材料的粘合强度的影响。用氢氧化钙、MTA 或生物活性玻璃 45S5 粉末暴露和浸润提取的人类磨牙的冠状牙本质。未浸润的牙本质标本作为对照。随后，牙本质被酸蚀或不酸蚀，剩余的碱含量通过水中的 pH 诱导测量。然后将蚀刻和冲洗系统（Adper Single Bond 2）在蚀刻牙本质上的剪切粘合强度与同一制造商的通用对应物（Single Bond [（Scotchbond）Universal] 的剪切粘合强度进行比较。使用单键对组间的数据进行比较方差分析和 Tukey 的 HSD。在健全的牙本质上，蚀刻和冲洗系统比通用系统更牢固（p < .05）。所有颗粒都使牙本质呈碱性。酸蚀降低了浸润牙本质中的碱含量。然而，没有蚀刻的通用系统的粘合强度值比蚀刻和冲洗对应物更强，后者失去了 60% 以上的粘合性。与蚀刻和冲洗对应物相比，通用粘合剂系统更不容易受到牙本质的碱性污染。基于所研究的两个系统的相似组成，这可能是由于其 10-MDP 组件。
