Abstract
Background and aim: Over the years, improvments have been done to simplify clinical bonding procedure. One of these material is Transbond™ Plus Self Etching. The aim of this study was to evaluate the effect of saliva contamination and reusing Transbond™ Plus Self Etching Primer (SEP) on shear bond strength of orthodontic brackets.
Materials and Methods: Fifty premolars divided into five groups of 10. Orthodontic brackets were bonded with Transbond XT adhesive (3M, Unitek) using the following treatment: Group1- Transbond™ Plus Self Etching Primer(SEP)/ Transbond XT adhesive/ Curing. Group2- Self-Etching Primer/ Curing/ Transbond XT adhesive / Curing. Group3- Self-Etching Primer/ Curing/ saliva contamination/ Transbond XT adhesive/ Curing. Group4- Self-Etching Primer/ Curing / saliva contamination/ Self-Etching Primer/ Transbond XT adhesive/ Curing. Group5- Self-Etching Primer/ Curing/saliva contamination/ Self-Etching Primer/ Curing/ Transbond XT adhesive/ Curing. Samples were stored for 24h in distilled water at 37 ˚C, then thermocycled for 1000 cycles (5-55˚C). Shear bond strength of each sample was obtained using a universal testing machine. Data were analyzed statistically. Using one way anaylisis & variance, Tukeey and Scheffe.
Result: Clinically acceptable bond strength was in all groups. There was no statistically significant difference between the groups.
Conclusion: Saliva contamination has no statistically significant effect on the shear bond strength of Self etching primer, however light curing of Self etching primer, before saliva contamination, increased the bond strength.
