To determine the enamel shear bond strength (SBS) of various established (Resulcin Aqua Prime & Monobond N [RA], Prompt L-Pot III [PLP]) and experimental (AC-Bond [AC], AC-Bond + Desensitizer [ACD]) self-etching adhesives in comparison to fourth (Total Etch, Primer and Bonding have separate liquids; OptiBond FL [FL]) and fifth-generation (Total Etch, Primer and Bonding "One Bottle"; Excite [EX], Gluma Comfort Bond [CB]) adhesives.
All adhesives were applied on flattened human enamel surfaces following the manufacturers' instructions and light-cured using a quartz-tungsten-halogen curing device. 3.5 x 2.0 mm Tetric Ceram A2 composite cylinders were sheared off (Zwick Universal-testing-machine 1445, 1 mm/min) after thermocycling (5-55 degrees C, 5000x). Normal distribution was tested for all groups and analysis of variance was conducted. The t-test (5% level, Bonferroni-correction) was used for statistical analysis to evaluate intergroup differences.
Shear bond strength in enamel: Resulcin Aqua Prime & Monobond N: 27.0 +/- 5.8 MPa, Prompt L-Pop III: 15.9 +/- 3.4 MPa, AC-Bond: 28.1 +/- 4.4 MPa, AC-Bond + Desensitizer: 22.2 +/- 4.1 MPa, OptiBond FL: 33.2 +/- 3.2 MPa, Excite: 30.5 +/- 5.1 MPa, Gluma Comfort Bond: 30.1 +/- 3.7 MPa. OptiBond FL demonstrated significantly higher SBS (p < 0.002) in enamel than Resulcin Aqua Prime & Monobond N, AC-Bond, AC-Bond + Desensitizer and Prompt L-Pop III. Resulcin Aqua Prime & Monobond N performed significantly better than Prompt L-Pop III, but did not differ from AC-Bond or AC-Bond + Desensitizer. The SBS values of Excite and Gluma Comfort Bond were both on the same level of significance as AC-Bond and Resulcin Aqua Prime & Monobond N, but the former showed superior results to AC-Bond + Desensitizer and Prompt L-Pop III. Prompt L-Pop III yielded significantly lower SBS-values than all the other products evaluated.
Resulcin Aqua Prime & Monobond N and AC-Bond did not differ significantly from established 5th-generation products. Further in-vivo studies are required to investigate intra-oral stability and resistance against changing forces and force directions.
测定各种已确立的(Resulcin Aqua Prime和Monobond N [RA]、Prompt L-Pot III [PLP])和实验性的(AC-Bond [AC]、AC-Bond +脱敏剂[ACD])自酸蚀粘结剂的釉质剪切粘结强度(SBS),并与第四代(全酸蚀,底漆和粘结剂有单独液体;OptiBond FL [FL])和第五代(全酸蚀,底漆和粘结剂“一瓶装”;Excite [EX]、Gluma Comfort Bond [CB])粘结剂进行比较。
按照制造商的说明,将所有粘结剂应用于平整的人釉质表面,并用石英-钨-卤素固化装置进行光固化。在热循环(5-55℃,5000次)后,将3.5×2.0 mm的Tetric Ceram A2复合圆柱体剪切下来(Zwick万能试验机1445,1 mm/min)。对所有组进行正态分布检验,并进行方差分析。采用t检验(5%水平,Bonferroni校正)进行统计分析,以评估组间差异。
釉质中的剪切粘结强度:Resulcin Aqua Prime和Monobond N:27.0±5.8 MPa,Prompt L-Pop III:15.9±3.4 MPa,AC-Bond:28.1±4.4 MPa,AC-Bond +脱敏剂:22.2±4.1 MPa,OptiBond FL:33.2±3.2 MPa,Excite:30.5±5.1 MPa,Gluma Comfort Bond:30.1±3.7 MPa。OptiBond FL在釉质中的SBS显著高于Resulcin Aqua Prime和Monobond N、AC-Bond、AC-Bond +脱敏剂和Prompt L-Pop III(p < 0.002)。Resulcin Aqua Prime和Monobond N的性能明显优于Prompt L-Pop III,但与AC-Bond或AC-Bond +脱敏剂没有差异。Excite和Gluma Comfort Bond的SBS值与AC-Bond和Resulcin Aqua Prime和Monobond N处于同一显著水平,但前者的结果优于AC-Bond +脱敏剂和Prompt L-Pop III。Prompt L-Pop III产生的SBS值明显低于所有其他评估产品。
Resulcin Aqua Prime和Monobond N以及AC-Bond与已确立的第五代产品没有显著差异。需要进一步的体内研究来调查口腔内的稳定性以及对变化的力和力方向的抵抗力。
