Abstract

Abstract: This study aimed to compare the surface roughness between different combinations of epoxy-coated and stainless-steel arch wires in ceramic and stainless-steel brackets.Materials and methods: Two types of arch wires with a gauge of 0.019x0.025were used in this study: Fantasia non-coated stainless steel arch wire (SSA) (n=18) and tooth tone Epoxy-coated stainless steel arch wires (ECSSA) (n=18). The two types of arch wires were slid on two types of brackets of premolars of slot size 0.022x0.030roth prescription (n=36) divided equally intomonocrystalline sapphire clear aesthetic ceramic brackets (CB) and Razor stainless steel bracket (SSB). The Ra surface roughness was measured using an atomic force microscope AFM to assess the wires before and after sliding them into ceramic and steel brackets. Six samples of wires received from the manufacturer were examined; additionally, six samples from each group of wires were taken after the friction test to examine the changes to the surface of the wires caused by the effect of the frictional force. For the statistical analysis, One-way ANOVA and Pairwise comparisons between groups, using the DUNCAN test at level of significance 0.05, by using SPSS software version 24.Results: ECSSA in CB had the highest value Ra (97 60.1), followed by epoxy wire in steel brackets Ra (96.152.9), followed by epoxy wire as received Ra (79 60.1), followed by steel wire in ceramic bracket Ra (50.6 24.3), followed by steel wire in steel bracket Ra (44.7 23.4), the lowest values shown in steel wire as received Ra (28.213.3). One-way ANOVA showed a significant difference between the tested groups (P=value: 0.05). Duncans test demonstrated significant differences among groups. Conclusion:Epoxy-coated SS arch wire combined with ceramic bracket shows the highest roughness properties, while SS arch wire combined with SS bracket and SS as received shows the lowest roughness properties.
