The use of fiber posts in endodontically treated primary maxillary central incisors improves the retention of composite resin restorations. The purpose of this study was to evaluate the effect of 4 different luting cements on fracture resistance of primary maxillary central incisors with fiber posts. In this in vitro study, 40 primary maxillary central incisors were endodontically treated and obturated with Metapex. They were then randomly divided into four groups (n=10) for cementation of fiber posts with GC Fuji I glass ionomer luting cement, Panavia F2.0 dual-cure luting cement, Panavia SA Luting Plus cement (self-adhesive), and TotalCem self-adhesive cement. After 1000 thermal cycles, the fracture resistance was measured. Data were statistically analyzed using ANOVA (alpha=0.05). The mean fracture resistance was 267.07±130.01N in TotalCem, 257.27±102.56N in Panavia F2.0 dual-cure cement, 227.82±110.40N in Panavia SA Luting Plus self-adhesive cement, and 220.89±59.96N in GC Fuji I glass ionomer group. There was no statistically significant difference in fracture resistance among the four groups (P=0.714). Type of luting cement had no significant effect on fracture resistance of primary maxillary central incisors with fiber posts. Nonetheless, TotalCem yielded the highest fracture resistance. Considering its self-adhesive property and easy workability, it can be a good option for cementation of fiber posts in endodontically treated primary central incisors.
在牙髓治疗后的上颌乳中切牙中使用纤维桩可提高复合树脂修复体的固位力。本研究的目的是评估4种不同的粘结水门汀对带纤维桩的上颌乳中切牙抗折性能的影响。在这项体外研究中，40颗上颌乳中切牙接受了牙髓治疗并用Metapex进行了根管充填。然后将它们随机分为四组（n = 10），分别用GC Fuji I玻璃离子粘结水门汀、Panavia F2.0双固化粘结水门汀、Panavia SA Luting Plus粘结剂（自粘结型）和TotalCem自粘结水门汀粘结纤维桩。经过1000次热循环后，测量抗折性能。数据采用方差分析进行统计学分析（α = 0.05）。TotalCem组的平均抗折力为267.07±130.01N，Panavia F2.0双固化水门汀组为257.27±102.56N，Panavia SA Luting Plus自粘结水门汀组为227.82±110.40N，GC Fuji I玻璃离子组为220.89±59.96N。四组之间的抗折性能无统计学显著差异（P = 0.714）。粘结水门汀的类型对带纤维桩的上颌乳中切牙的抗折性能没有显著影响。尽管如此，TotalCem的抗折力最高。考虑到其自粘结性能和易于操作性，它可以是牙髓治疗后的乳中切牙纤维桩粘结的一个良好选择。
