Comparative evaluation of retentive strength of Figaro crowns and stainless steel crowns luted with glass ionomer cement and resin-modified glass ionomer cement – An in vitro study

Abstract

Aims: To compare the tensile strength of Figaro crowns and SSC using two different kinds of luting cements, i.e. GIC and RM-GIC. Methods and Material: Forty extracted human deciduous molars are used in this study; tooth preparation was done to receive the crowns and were categorized into two groups: stainless steel crowns and Figaro crowns that were further divided into two subgroups, one that was luted with GIC and the other with RM-GIC. Then, the tensile strength of the crowns was evaluated with a universal testing machine. Statistical analysis used: Data were analyzed by one-way ANOVA and post hoc Tukey’s multiple comparison tests. Results: Stainless steel crowns had showed greater tensile strength than Figaro when luted with GIC; in contrast with RMGIC, Figaro exhibited greater retentive strength. Conclusions: GIC exhibited highest retentive strength as luting agents for stainless steel crowns.
