Intoduction: Fixed orthodontic treatment has a high risk of enamel demineralization. Sealant containing
selenium is a material that has been developed to prevent enamel demineralization and stated to be
applicable as a primer bracket adhesion. Aim and Objective: This aim of this study was to investigate
the shear bond strength (SBS) of an orthodontic bracket after application of sealant containing selenium
as a primer. Materials and Methods: A total of 100 extracted human premolars were used in this study,
which were randomly divided into two groups. Group I consisted of 50 teeth as the control group, to
which a conventional primer (CP) was applied, whereas for group II comprising 50 teeth, a sealant
containing selenium selenium primer (SP) was applied. SBS of the orthodontic brackets was measured
using a universal testing machine. The adhesive remnant index (ARI) scores were calculated to
determine the location of the bond failure using a stereomicroscope. A t test was used for analyzing
the SBS data, whereas the Mann–Whitney test was used for analyzing the ARI scores. Results: There
was no significant SBS difference (P > 0.05) between CP and SP groups. CP groups showed slightly
higher SBS [9.05 ± 3.10 megapascal (MPa)] than that in the SP groups (8.21 ± 3.78 MPa). The bond
failures of both the groups occurred at the adhesive–adhesive interface. Conclusion: The results showed
that sealant containing selenium can be used as a primer within orthodontic adhesive material, as the
physical–mechanical properties remained unchanged.
