title: Effect of Self-etch Primer-adhesive and Conventional Adhesive Systems on the Shear Bond Strength and Bond Failure of Orthodontic Brackets: A Comparative Study.
abstract: 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.
  
  
  
  In this in vitro experimental study, 60 human premolar teeth extracted for orthodontic treatment were collected. The samples were randomly divided into three groups comprising of 20 teeth in each group. Shear bond strength and ARI scores for the specimens were measured. Comparison was done using one way ANOVA and Chi-square test.
  
  
  
  Fourth generation bonding adhesive system depicted similar bond strength to fifth generation bonding adhesive system. Both fourth and fifth generation exhibited higher shear bond strength as compared to sixth generation bonding adhesive system.
  
  
  
  Fourth and fifth generation exhibited higher shear bond strength as compared to sixth generation bonding adhesive system but the sixth generation has clinically acceptable shear bond strength. Also, it was found that sixth generation leaves less residual adhesive on the tooth after bracket removal.
