TI  - Self-etching primer and a non-rinse conditioner versus phosphoric acid: 
      alternative methods for bonding brackets.
PG  - 173-8
AB  - The objective of this study was to evaluate the effectiveness of a self-etching 
      primer, Transbond Plus Self Etching Primer (TSEP, 3M Unitek), and a non-rinse 
      conditioner (NRC, Dentsply DeTrey) for bonding brackets, compared with the 
      acid-etch technique. The brackets were bonded to extracted premolars using 
      Transbond XT (3M Unitek). One of the following three conditioning protocols were 
      used: (1) 37 per cent phosphoric acid (n = 25), (2) TSEP (n = 25), and (3) NRC (n 
      = 15). Shear bond strength (SBS) was measured with a universal testing machine. 
      The adhesive remaining after debonding was determined using image analysis 
      equipment. Scanning electron microscope (SEM) observations were also carried out 
      on 12 premolars to observe the enamel surfaces. No significant differences were 
      observed in SBS between the three groups (P = 0.56). TSEP and NRC left 
      significantly less adhesive on the tooth than the traditional acid-etch technique 
      (P = 0.004 and P = 0.000, respectively). NRC left significantly less adhesive 
      than TSEP (P = 0.001). SEM observations showed that NRC produced a less 
      aggressive etch pattern than TSEP, and that the etching effect of TSEP 
      approximated that of phosphoric acid.
