Cyclic shear fatigue of orthodontic brackets bonded to enamel using self-adhering flowable composites.

ABSTRACT:

Background

Self-adhering composites are claimed to bond to teeth without prior acid etching and bonding steps. This study aimed to evaluate the cyclic shear fatigue (CSF) of metal orthodontic brackets bonded to enamel using self-adhering flowable composites (Constic and Vertise^TM Flow) in comparison with that of total-etch and self-etch adhesives.

Materials and methods

Twenty-five human premolars comprising 100 surfaces were randomly divided into four groups (n = 25): total-etch, self-etch, Constic, and Vertise^TM Flow. A total of 10 surfaces were used per group for baseline static shear bond strength (SSBS) evaluation and 15 surfaces for CSF evaluation. Each tooth was treated with the four bonding agents. Both SSBS and CSF were evaluated using a univers
