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.
