Abstract

Background: Although stainless-steel crowns (SSCs) have a high clinical success rate, a key reason for its clinical failure is loss of crown due to cementation failure. Therefore, the choice of cementation material has an important effect on SSC retention.

Aim: To evaluate the retention strength of SSCs luted on primary molars with glass ionomer cement (GIC), resin-modified glass ionomer cement (RMGIC) and resin-based cement.

Materials and methods: A total of 45 freshly extracted human primary molars were prepared to receive SSCs and randomly divided into three equal groups, to receive the different luting cements: conventional glass ionomer, resin-modified glass ionomer and resin luting cement. The teeth were then stored in artificial saliva for 24 h. The retentive strength of the crowns was determined using a specially designed Universal Testing Machine.

Statistical analysis: To compare the mean retentive strength between cements, ANOVA with post hoc test was applied.

Results: Mean retentive strength for GC GOLD Label 1 group was 230.30 ± 13.46; GC FujiCEM group was 194.78 ± 13.03; and 269.25 ± 11.28 for the GC G-CEM One group. A comparison of luting cement showed the retentive strength of GC G-CEM One cement significantly higher than the rest of the two cements (P < 0.001). The retentive strength of GC GOLD Label 1 cement was significantly higher than GC FujiCEM cement (P < 0.001).

Conclusion: Resin cement (GC G-CEM One) significantly improved crown retention when compared with RMGIC (GC FujiCem) and GIC (GC Gold label 1).

三种不同固位剂对不锈钢冠固位强度的体外研究。

背景：尽管不锈钢冠（ssc）具有很高的临床成功率，但其临床失败的一个关键原因是由于固相失败导致的冠脱落。因此，胶结材料的选择对SSC固位有重要影响。目的：评价玻璃离子水门合剂（GIC）、树脂改性玻璃离子水门合剂（RMGIC）和树脂基水门合剂在一磨牙上的固位强度。材料与方法：将45颗新鲜拔除的人一磨牙随机分为3组，分别接受常规玻璃离聚体、树脂改性玻璃离聚体和树脂离聚体粘结剂。然后将牙放在人工唾液中保存24小时。使用专门设计的通用试验机测定冠的固位强度。统计分析：采用方差分析和事后检验比较两种骨水泥的平均固位强度。结果：GC GOLD Label 1组的平均保持强度为230.30±13.46；GC FujiCEM组为194.78±13.03；GC - cem 1组为269.25±11.28。结果表明，GC - cem 1型水泥的固位强度显著高于其余两种水泥（P < 0.001）。GC GOLD Label 1水泥的固位强度显著高于GC FujiCEM水泥（P < 0.001）。结论：与RMGIC （GC FujiCem）和GIC （GC Gold label 1）相比，树脂水泥（GC G-CEM One）可显著改善冠固位。
