Comparative Evaluation of Bond Strength of Different Luting Cements for Cementation of Stainless Steel Bands on Primary Molar Crowns (Stainless Steel and Zirconia Crowns): An In Vitro Study.

Abstract

Aim and backgroundPrimary teeth are the valuable assets of a child. Apart from the obvious function of delivering esthetics, their most important function is space maintenance for the succeeding permanent teeth. At times, due to unavoidable pathological conditions, there is premature loss of primary teeth. Space maintainers can either be banded to the enamel surfaces of healthy adjacent teeth or to the surfaces of full coronal restorations, the most common ones being stainless steel crowns (SSCs) and zirconia crowns (ZCs). Due to esthetic demands, ZCs have started replacing SSCs and therefore, there needs to be data on the banding of space maintainers on ZCs and the bond strengths obtained on cementations. Thus, the present study planned to evaluate and compare the bond strengths obtained by the banding of stainless steel bands (SSBs) over SSCs and ZCs using type I glass ionomer cement (GIC) and self-adhesive resins.Materials and methodsSixty primary right mandibular molars were divided into four groups, group I, with cementation of SSB on SSC with type I GIC; group II, with cementation of SSB on SSC with self-adhesive resin cement; group III, with cementation of SSB on ZC with type I GIC; and group IV, with cementation of SSB on ZC with self-adhesive resin cement.ResultsThe mean bond strength value of GIC as luting cements in group I is 1.13 ± 0.075 MPa. The mean bond strength value of self-adhesive resin as luting cements in group II is 1.70 ± 0.104 MPa. The mean bond strength value of GIC as luting cements in group III is 1.38 ± 0.100 MPa. The mean bond strength value of self-adhesive resin as luting cements in group IV is 2.06 ± 0.119 MPa.ConclusionThe bond strength of self-adhesive resin was higher when SSB was cemented over SSC when compared with the bond strength of GIC when SSB was cemented over ZC.How to cite this articleKalaskar R, Ijalkar R, Kalaskar A, et al.
