The purpose of this study was to evaluate the effect of etidronic acid on bond strength to coronal dentin.
A total of 75 human mandibular molars were sectioned 3 mm below the occlusal surface and then randomly divided into five groups according to irrigation solution used ( = 15): Group 1: 5 ml 2.5% sodium hypochlorite (NaOCl) +5 ml distilled water; Group 2: 5 ml 2.5% NaOCl + 5 ml 17% ethylenediaminetetraacetic acid (EDTA); Group 3: 10 ml mixture of 5% NaOCl and 18% 1-hydroxyethylidene-1,1-bisphosphonate (HEBP); Group 4: 5 ml mixture of 5% NaOCl and 18% HEBP + 5 ml 17% EDTA; and Group 5: 5 ml mixture of 5% NaOCl and 18% HEBP + 5 ml distilled water. Thereafter, Clearfil SE bond was applied to the dentin surfaces and then, composite build-ups were created using Tygon tubes for the microshear bond strength test. Data were analyzed using the one-way analysis of variance and Tukey test.
When compared to Groups 3, 4, and 5, Groups 1 and 2 showed significantly higher bond strength values ( < 0.05). However, there was no statistically significant difference between Groups 1 and 2 and between Groups 3, 4, and 5 ( > 0.05).
HEBP adversely affected the bond strength of the tested adhesive to coronal dentin.
本研究旨在评估依替膦酸对牙冠部牙本质粘结强度的影响。
总共75颗人类下颌磨牙在咬合面下方3毫米处进行切片，然后根据使用的冲洗液随机分为五组（每组n = 15）：第1组：5毫升2.5%次氯酸钠（NaOCl）+ 5毫升蒸馏水；第2组：5毫升2.5% NaOCl + 5毫升17%乙二胺四乙酸（EDTA）；第3组：10毫升5% NaOCl和18% 1-羟基亚乙基-1,1-二膦酸（HEBP）的混合液；第4组：5毫升5% NaOCl和18% HEBP的混合液+ 5毫升17% EDTA；第5组：5毫升5% NaOCl和18% HEBP的混合液+ 5毫升蒸馏水。此后，将Clearfil SE粘结剂应用于牙本质表面，然后使用泰贡管制作复合树脂堆积体进行微拉伸粘结强度测试。数据采用单因素方差分析和Tukey检验进行分析。
与第3、4和5组相比，第1和2组显示出显著更高的粘结强度值（P < 0.05）。然而，第1和2组之间以及第3、4和5组之间没有统计学上的显著差异（P > 0.05）。
HEBP对测试粘结剂与牙冠部牙本质的粘结强度有不利影响。
