Am: The purpose of ths study was to evaluate the effect of etdronc acd on bond strength to coronal dentn. Materals and Methods: A total of 75 human mandbular molars were sectoned 3 mm below the occlusal surface and then randomly dvded nto fve groups accordng to rrgaton soluton used (n = 15): Group 1: 5 ml 2.5% sodum hypochlorte (NaOCl) +5 ml dstlled water; Group 2: 5 ml 2.5% NaOCl + 5 ml 17% ethylenedamnetetraacetc acd (EDTA); Group 3: 10 ml mxture of 5% NaOCl and 18% 1-hydroxyethyldene-1,1bsphosphonate (HEBP); Group 4: 5 ml mxture of 5% NaOCl and 18% HEBP + 5 ml 17% EDTA; and Group 5: 5 ml mxture of 5% NaOCl and 18% HEBP + 5 ml dstlled water. Thereafter, Clearfl SE bond was appled to the dentn surfaces and then, composte buld-ups were created usng Tygon tubes for the mcroshear bond strength test. Data were analyzed usng the one-way analyss of varance and Tukey test. Results: When compared to Groups 3, 4, and 5, Groups 1 and 2 showed sgnfcantly hgher bond strength values (P < 0.05). However, there was no statstcally sgnfcant dfference between Groups 1 and 2 and between Groups 3, 4, and 5 (P > 0.05). Concluson: HEBP adversely affected the bond strength of the tested adhesve to coronal dentn.
