Abstract

Aim: This study aimed to determine if flowable restorative light cure composites can be used effectively for routine orthodontic bracket bonding, thereby reducing 4 in the dental office and preserving the surface enamel. Materials and methods: Ninety extracted human premolars were divided into three equal groups. Pre-adjusted edgewise (PAE) brackets were bonded to prepared enamel surface using conventional orthodontic resin Transbond XT (control), GC-G-ænial, and Anabond Stedman. Debonding was performed with a shearing force using a universal testing machine to test shear bond strength (SBS). The residual adhesive on the enamel surface was evaluated using the adhesive remnant index (ARI). In addition, representative samples from each group were examined by scanning electron microscopy (SEM) and elemental composition was quantified with energy dispersive X-ray spectrometry (EDX). Results: There was a statistically significant difference (p = 0.000) between all three materials with respect to bond strength and ARI. The SBS values of Transbond XT, GC-G-ænial, and Anabond Stedman were found to be 13.10 ± 3.46, 9.8027 ± 2.05, and 6.2720 ± 1.39 MPa, respectively, signifying acceptable bond strength. The greatest frequency for Transbond XT and GC-G-ænial was observed at an ARI score of 1, whereas Anabond Stedman displayed an ARI score of 2. Morphologically different types of images were observed under the SEM. Similar elements with varied concentrations were detected in EDX. An insignificant amount of calcium was detected in all the samples evaluated under EDX indicating preservation of enamel. Conclusion: In this study, Transbond XT was found to be relatively better than GC-G-ænial Universal Flo and Anabond Stedman Flowable composite. The use of flowable restorative light cure composites can be advocated for orthodontic bracket bonding as acceptable SBS values were attained. Clinical significance: The rheological properties and esthetics of the flowable restorative materials make them versatile, economical, and favorable for orthodontic bracket bonding, thereby reducing the in-office armamentarium and the need for an additional orthodontic bonding material.
