Effect of Self-etch Primer-adhesive and Conventional Adhesive Systems on the Shear Bond Strength and Bond Failure of Orthodontic Brackets: A Comparative Study.

Background: Prompt-L-Pop is a sixth generation bonding system contains methacrylated phosphoric acid esters that combine an acidic component for etching the enamel and a primer, is an all-in-one adhesive. This study was undertaken to compare the bonding strength of brackets to enamel with traditional bonding technique and the new Prompt-L-Pop system using the same composite resin.

Materials And Methods: In this in vitro experimental study, 60 human premolar teeth extracted for orthodontic treatment were collected.

Comparison of Bond Strength of Brackets with Foil Mesh and Laser Structure Base using Light Cure Composite Resin: An in vitro Study.

Background And Objectives: The purpose of this in vitro study was to evaluate the bond strength of the laser-etched base bracket, site of bond failure, and evaluate for enamel remnants on the bracket base after debonding, when compared to foil mesh base bracket.

Materials And Methods: Sixty noncarious, human premolar extracted for the orthodontic treatment were used for this study. The teeth were randomly divided into two groups containing 30 teeth each, which were bonded with laser-etched base bracket and mesh base bracket using light cure resin.
