Retentive Strength of Stainless-Steel Crown with Three Different Luting Cements - An In vitro Study
Year: 2025
Type: article
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).
