GC Fuji Ⅸ and reinforced glass-ionomer cements for repairing wedge-shaped defects in old people: 1-year follow-up comparison / 中国组织工程研究

ABSTRACT

BACKGROUND: As a kind of filling material for wedge-shaped defects, GC Fuji Ⅸ glass-ionomer cement has arose more and more attention. However, the comparison of repair results between GC Fuji Ⅸ glass-ionomer cement and reinforced glass-ionomer cement are poorly understood. OBJECTIVE: To compare the clinical effect of GC Fuji Ⅸ glass-ionomer cement and reinforced gtass-ionomer cement for repairing wedge-shaped defects of old people. METHODS: Totally 80 teeth were randomly divided into 2 groups, and filled by GC Fuji Ⅸ glass-ionomer cement (experimental group) and reinforced glass-ionomer cement (control group), respectively. The clinical effect of 2 materials were evaluated on color match, edge density heterozygosity, restoration integrity, occurrence of secondary caries and pulp symptom at immediately, 3 months, 6 months and 1 year after placement. RESULTS AND CONCLUSION: The color match of the experimental group was better than that of the control group at 3 months, 6 months and 1 year after placement (P < 0.05); and the edge density heterozygosity of the experimental group was superior to the control group at 6 months and 1 year after placement (P < 0.05); in addition, the restoration integrity of the experimental group was surpass the control group at 1 year after placement (P < 0.05). It demonstrated that GC Fuji IX glass-ionomer cement is an ideal choice for wedge-shaped defects of old people, which exhibits superior effects to reinforced glass-ionomer cement in 1-year follow-up.
