Abstract The present study aimed to evaluate the effect of universal adhesive pretreatment on the dentin bond strength of a resin-modified glass ionomer cement after radiotherapy. One hundred human third molars without caries were employed. One-half of the teeth were irradiated (total IR = 70.2 Gy). Both the irradiated and non-irradiated teeth were randomly divided into five groups (n = 10) according to dentin surface pretreatments: Single Bond Universal (3 M Oral Care), Gluma Bond Universal (Heraeus Kulzer), Prime&Bond Elect (Dentsply), Cavity Conditioner (GC) and control (no surface treatment). After Fuji II LC (GC) was bonded to the dentin surfaces, the specimens were stored for 7 days at 37 °C. The specimens were segmented into microspecimens, which were tested in the μTBS device (1.0 mm/min). Failure modes were analyzed with stereomicroscope and scanning electron microscope. Data were analyzed using two-way ANOVA and Duncan tests (p = 0.05). The radiotherapy induced a decrease in the bond strength of Fuji II LC in all experimental groups (p < 0.05). All surface pretreatments increased the bond strength of Fuji II LC to non-irradiated and irradiated dentin (p < 0.05). The highest bond strength of Fuji II LC to irradiated dentin was obtained with Gluma Bond Universal, followed by Single Bond Universal and Prime&Bond Elect, then Cavity Conditioner (p < 0.05). The radiotherapy negatively influenced the bond strength of Fuji II LC regardless of surface pretreatments. The pretreatment with universal adhesives improved the bonding performance of Fuji II LC after radiotherapy.

树脂改性玻璃离聚物与通用粘合剂对放疗后牙本质的粘接效果

摘要 本研究旨在评估通用粘合剂预处理对放疗后树脂改性玻璃离子水门汀牙本质粘合强度的影响。使用了一百颗没有龋齿的人类第三磨牙。一半的牙齿受到辐射(总 IR = 70.2 Gy)。根据牙本质表面预处理将照射和未照射的牙齿随机分为五组(n = 10):Single Bond Universal(3 M Oral Care)、Gluma Bond Universal(Heraeus Kulzer)、Prime&Bond Elect(Dentsply)、Cavity调节剂 (GC) 和对照(无表面处理)。在将 Fuji II LC (GC) 粘合到牙本质表面后,将样品在 37 °C 下储存 7 天。样品被分割成微型样品,在 μTBS 设备(1.0 毫米/分钟)中进行测试。用立体显微镜和扫描电子显微镜分析失效模式。使用双向方差分析和邓肯检验 (p = 0.05) 分析数据。放疗导致所有实验组中富士 II LC 的粘合强度降低(p < 0.05)。所有表面预处理都增加了 Fuji II LC 与未辐照和辐照牙本质的粘合强度 (p < 0.05)。Fuji II LC 与辐照牙本质的最高粘合强度是使用 Gluma Bond Universal 获得的,其次是 Single Bond Universal 和 Prime&Bond Elect,然后是 Cavity Conditioner (p < 0.05)。无论表面预处理如何,放疗都会对 Fuji II LC 的粘合强度产生负面影响。通用粘合剂的预处理提高了Fuji II LC在放疗后的粘合性能。使用双向方差分析和邓肯检验 (p = 0.05) 分析数据。放疗导致所有实验组中富士 II LC 的粘合强度降低(p < 0.05)。所有表面预处理都增加了 Fuji II LC 与未辐照和辐照牙本质的粘合强度 (p < 0.05)。Fuji II LC 与辐照牙本质的最高粘合强度是使用 Gluma Bond Universal 获得的,其次是 Single Bond Universal 和 Prime&Bond Elect,然后是 Cavity Conditioner (p < 0.05)。无论表面预处理如何,放疗都会对 Fuji II LC 的粘合强度产生负面影响。通用粘合剂的预处理提高了Fuji II LC在放疗后的粘合性能。使用双向方差分析和邓肯检验 (p = 0.05) 分析数据。放疗导致所有实验组中富士 II LC 的粘合强度降低(p < 0.05)。所有表面预处理都增加了 Fuji II LC 与未辐照和辐照牙本质的粘合强度 (p < 0.05)。Fuji II LC 与辐照牙本质的最高粘合强度是使用 Gluma Bond Universal 获得的,其次是 Single Bond Universal 和 Prime&Bond Elect,然后是 Cavity Conditioner (p < 0.05)。无论表面预处理如何,放疗都会对 Fuji II LC 的粘合强度产生负面影响。通用粘合剂的预处理提高了Fuji II LC在放疗后的粘合性能。放疗导致所有实验组中富士 II LC 的粘合强度降低(p < 0.05)。所有表面预处理都增加了 Fuji II LC 与未辐照和辐照牙本质的粘合强度 (p < 0.05)。Fuji II LC 与辐照牙本质的最高粘合强度是使用 Gluma Bond Universal 获得的,其次是 Single Bond Universal 和 Prime&Bond Elect,然后是 Cavity Conditioner (p < 0.05)。无论表面预处理如何,放疗都会对 Fuji II LC 的粘合强度产生负面影响。通用粘合剂的预处理提高了Fuji II LC在放疗后的粘合性能。放疗导致所有实验组中富士 II LC 的粘合强度降低(p < 0.05)。所有表面预处理都增加了 Fuji II LC 与未辐照和辐照牙本质的粘合强度 (p < 0.05)。Fuji II LC 与辐照牙本质的最高粘合强度是使用 Gluma Bond Universal 获得的,其次是 Single Bond Universal 和 Prime&Bond Elect,然后是 Cavity Conditioner (p < 0.05)。无论表面预处理如何,放疗都会对 Fuji II LC 的粘合强度产生负面影响。通用粘合剂的预处理提高了Fuji II LC在放疗后的粘合性能。Fuji II LC 与辐照牙本质的最高粘合强度是使用 Gluma Bond Universal 获得的,其次是 Single Bond Universal 和 Prime&Bond Elect,然后是 Cavity Conditioner (p < 0.05)。无论表面预处理如何,放疗都会对 Fuji II LC 的粘合强度产生负面影响。通用粘合剂的预处理提高了Fuji II LC在放疗后的粘合性能。Fuji II LC 与辐照牙本质的最高粘合强度是使用 Gluma Bond Universal 获得的,其次是 Single Bond Universal 和 Prime&Bond Elect,然后是 Cavity Conditioner (p < 0.05)。无论表面预处理如何,放疗都会对 Fuji II LC 的粘合强度产生负面影响。通用粘合剂的预处理提高了Fuji II LC在放疗后的粘合性能。
