Abstract：
UNASSIGNED: The objective of the study was to evaluate two translucent resin composite systems for customizing light-polymerized fiber posts with light-emitting diode (LED) curing units regarding adhesion using conventional cement at 24 h and 6 months.
UNASSIGNED: This was an experimental in vitro study.
UNASSIGNED: Forty roots were prepared and divided into four groups (n = 10): ZV-Z350 resin and LED Valo; ZR-Z350 resin and LED Radii-Cal; OV-Opallis resin and LED Valo; and OR-Opallis resin and LED Radii-Cal. The fiber post was customized and cemented with conventional resin cement and was photoactivated by two different sources.
UNASSIGNED: The data were subjected to two-way ANOVA and Tukey\'s post hoc tests (P = 0.05). The data regarding the pattern of adhesive failures were described in terms of the frequency of occurrence in each third of the postspace.
UNASSIGNED: Both at 24 h and 6 months, bond strength among groups was similar, regardless of the analyzed postspace 3rd (P > 0.05). Adhesive failure Type 4 was the most frequent in all thirds.
UNASSIGNED: Customizing the fiber post with Z350 and Opallis has the same effect on bond strength and adhesive failure pattern, regardless of the LED curing units used for photopolymerization.

摘要：
■研究的目的是评估两种半透明树脂复合材料系统，用于定制具有发光二极管（LED）固化单元的光聚合纤维柱，其在24小时和6个月时使用常规水泥进行粘合。
■这是一项体外实验研究。
■制备40根并分成四组(n=10):ZV-Z350树脂和LEDValo;ZR-Z350树脂和LED半径-Cal;OV-Opallis树脂和LEDValo;和OR-Opallis树脂和LED半径-Cal。纤维桩是定制的，并用常规树脂水泥胶结，并通过两种不同的来源进行光活化。
■对数据进行了双向方差分析和Tukey的事后检验（P=0.05）。根据后空间的三分之一中发生的频率来描述有关粘合失效模式的数据。
■在24小时和6个月时，组间的粘结强度相似，无论分析后空间如何（P>0.05）。粘合剂失效类型4在所有三分之一中最常见。
■使用Z350和Opallis定制纤维桩对粘合强度和粘合失效模式具有相同的作用，无论用于光聚合的LED固化单元。
