Abstract
Aim and background: The retention of the band and loop space maintainer over the stainless steel crowns (SSCs) dictates the success of the space maintainer. Using two widely used luting agents, this study assesses the binding strength between SS bands and the most popular SSCs as well as the recently released Bioflx crowns.
Materials and methods: This in vitro study consisted of 48 samples divided into four groups. Type I glass ionomer cement (GIC) and resin-modified glass ionomer cement (RMGIC) were used to cement stainless steel (SS) bands over SSCs and Bioflx crowns. The shear bond strength was tested using a universal testing apparatus. To determine the degree of significance, one-way analysis of variance (ANOVA), post-hoc Tukey's test, and a p-value maintained at ≤0.05 were utilized.
Results: The shear bond strength between the SSC and RMGIC (0.908 ± 0.20 MPa) was statistically significant and higher than between the SSC and GIC (0.362 ± 0.21 MPa). Though not statistically significant, the binding strength between Bioflx crowns and GIC was stronger than between Bioflx crowns and RMGIC.
Conclusion: The SS bands bonded well to the SSCs with RMGIC, and there was no significant difference between the SSCs and Bioflx crowns with GIC as the luting agent. Cohesive failures were common with GIC, and adhesive failures were common with RMGIC in both crowns.
Clinical significance: The present study's findings can help clinicians make informed decisions when choosing crowns and luting agents for teeth with SSCs.
