TI  - Shear bond strength of precoated and uncoated brackets using a self-etching 
      primer.

AB  - OBJECTIVE: To test the hypothesis that there are no significant differences in 
      the shear bond strength or the adhesive remaining on the tooth after debonding 
      between precoated and uncoated brackets using a self-etching primer. MATERIALS 
      AND METHODS: APC Plus precoated brackets and uncoated brackets were bonded with 
      Transbond XT adhesive using the self-etching primer Transbond Plus Self-Etching 
      Primer (TPSEP). The brackets were bonded to extracted human premolars and 
      categorized into two groups: (1) TPSEP/Transbond XT and (2) TPSEP/APC Plus. Shear 
      bond strength was measured with a universal testing machine. The adhesive remnant 
      on each tooth after debonding was quantified with image analysis equipment. 
      Scanning electron microscope (SEM) observations of enamel surfaces treated with 
      TPSEP were also carried out. RESULTS: No significant differences were observed in 
      the shear bond strengths for the two groups evaluated (P < .05). TPSEP/APC Plus 
      left significantly less adhesive on the tooth after debonding than did 
      TPSEP/Transbond XT (P < .05). It was observed that SEM left a porous and 
      potentially retentive surface. CONCLUSIONS: There was no significant difference 
      in the bond strength of the two systems tested, but there was a significant 
      difference in the percentage of area of adhesive remaining on the tooth.
