: It has been shown that the irrigating solutions and medicament used during root canal treatment may affect the bonding strength. The aim of this study was to evaluate the effect of triple antibiotic paste (TAP), double antibiotic paste (DAP) and calcium hydroxide (CH) on the bond strength to root dentin of self-adhesive resin cement. : Forty-eight single-rooted human teeth were prepared and randomly divided into one control and three experimental groups (dressing with TAP, DAP or CH). After removal of intracanal dressing, post-spaces were created and fiber posts cemented to the root canal using a self-adhesive resin cement. A push-out test was performed. The data obtained from the push-out test were analyzed using analysis of variance and Bonferroni tests ( = 0.05). : TAP decreased the bond strength of self-adhesive resin cement bond strength to root dentin compared to the control group ( = 0.012), while CH and DAP did not influence this ( > 0.05). The majority of specimens exhibited adhesive failures. : TAP decreased the bond strength of self-adhesive to the root dentin compared to the control group.
已有研究表明，根管治疗期间使用的冲洗液和药物可能会影响粘结强度。本研究的目的是评估三联抗生素糊剂（TAP）、双联抗生素糊剂（DAP）和氢氧化钙（CH）对自粘结树脂水门汀与牙根牙本质粘结强度的影响。48颗单根人牙经过预备后随机分为1个对照组和3个试验组（分别用TAP、DAP或CH进行根管封药）。去除根管内封药后，制备桩道，并用自粘结树脂水门汀将纤维桩粘结至根管内。进行推出试验。使用方差分析和Bonferroni检验（α = 0.05）对推出试验获得的数据进行分析。与对照组相比，TAP降低了自粘结树脂水门汀与牙根牙本质的粘结强度（P = 0.012），而CH和DAP则无此影响（P > 0.05）。大多数标本表现为粘结失败。与对照组相比，TAP降低了自粘结剂与牙根牙本质的粘结强度。
