Abstract

OBJECTIVES

Long-term survival of two highly viscous glass ionomer cements (Fuji IX GP Fast and Equia Fil) over a period of 6 years in vivo.

METHODS

A total of 85 two- or three-surface class II restorations, comprising 43 Equia Fil / Equia Coat and 42 Fuji IX GP Fast / Fuji Coat LC, were placed in 34 patients. The restorations were re-evaluated after 6 years using the FDI criteria. The statistical analysis was performed with Fisher's exact test, the Wilcoxon signed-rank test, the Mann-Whitney U test and the Kaplan-Meier method.

RESULTS

Forty-four restorations (22 Equia Fil and 22 Fuji IX GP Fast) could be assessed at the 6-year follow-up. During the whole study period, eight failures, four for each material, were observed. The main reasons for failure were material fractures and retention loss, which were partly combined with poor marginal adaptation or poor proximal anatomical form. Two failures may be attributed to insufficient application of the materials, as suspected according to the radiographs. The Kaplan-Meier survival proportion for Equia Fil restorations at 6 years was 86.5% and that for Fuji IX GP Fast at 6 years was 86.8% (log-rank p = 0.907). During the period from 3 to 6 years, only one filling in each group failed.

CONCLUSION

Both materials showed acceptable and comparable survival rates after 6 years.

CLINICAL SIGNIFICANCE

Highly viscous glass ionomer cement can be an acceptable restoration material for smaller class II cavities.

摘要

目的

研究两种高粘性玻璃离子水门汀（Fuji IX GP Fast 和 Equia Fil）在体内长达 6 年的长期生存情况。

方法

共有 85 例 2 或 3 面 II 类修复体，包括 43 例 Equia Fil/Equia Coat 和 42 例 Fuji IX GP Fast/Fuji Coat LC，在 34 例患者中进行了放置。6 年后，采用 FDI 标准对修复体进行重新评估。采用 Fisher 确切检验、Wilcoxon 符号秩检验、Mann-Whitney U 检验和 Kaplan-Meier 法进行统计学分析。

结果

44 例修复体（22 例 Equia Fil 和 22 例 Fuji IX GP Fast）可在 6 年随访时进行评估。在整个研究期间，观察到 8 例失败，每种材料各有 4 例。失败的主要原因是材料断裂和保留损失，部分与边缘适应性差或近中解剖形态不良有关。2 例失败可能归因于材料应用不足，根据射线照片怀疑如此。6 年时 Equia Fil 修复体的 Kaplan-Meier 生存比例为 86.5%，6 年时 Fuji IX GP Fast 的生存比例为 86.8%（对数秩检验 p=0.907）。在 3 至 6 年期间，每组只有 1 例填充物失败。
