This study evaluated the effect of resin cements and post-space irrigation solutions on the push-out bond strength of diabetic and non-diabetic dentin. A total of 160 human central teeth (80 diabetic, 80 non-diabetic) were prepared using X5 files and obturated with AH Plus sealer and X5 gutta-percha. Post spaces were prepared, and teeth were divided into eight groups based on resin cements (Variolink N, Panavia SA Universal) and irrigation protocols (saline, saline + 2% CHX). A 1 mm slice from each tooth's middle third was tested for push-out bond strength. Statistical analysis was performed using three-way ANOVA and Tukey HSD tests. In non-diabetic dentin, saline + CHX with Variolink N achieved the highest bond strength. In diabetic dentin, saline with Panavia SA Universal resulted in the lowest bond strength ( < 0.05). The dentin type, resin cement, and irrigation solution significantly impacted fiber post bond strength, and CHX irrigation improved it.
本研究评估了树脂水门汀和桩道冲洗液对糖尿病和非糖尿病患者牙本质推出粘结强度的影响。总共160颗人正中牙（80颗糖尿病患者的牙，80颗非糖尿病患者的牙）使用X5锉进行预备，并用AH Plus封闭剂和X5牙胶尖进行充填。制备桩道，根据树脂水门汀（Variolink N、Panavia SA通用型）和冲洗方案（生理盐水、生理盐水+2%氯己定）将牙齿分为八组。从每颗牙齿中1/3处切取1mm厚的切片，测试其推出粘结强度。使用三因素方差分析和Tukey HSD检验进行统计分析。在非糖尿病患者牙本质中，使用Variolink N并配合生理盐水+氯己定可获得最高的粘结强度。在糖尿病患者牙本质中，使用Panavia SA通用型并配合生理盐水导致粘结强度最低（P<0.05）。牙本质类型、树脂水门汀和冲洗液对纤维桩粘结强度有显著影响，氯己定冲洗可改善粘结强度。
