【 摘 要 】

Despite rapid developments in adhesive technology, contamination of bonding surfaces remains a major problem. The aim of this study was to evaluate the influence of contamination on shear bond strength of two adhesive systems: resin-modified glass ionomer cement (Fuji Ortho LC; GC America Corp) and Moist Insensitive Primer (Transbond MIP, 3M Unitek) combination with Transbond XT (light-activated), under different enamel conditions. Metal brackets were bonded to the buccal surfaces of 42 human premolars. The total sample was divided into 6 groups (n = 7 teeth) and brackets were bonded with one of the 2 adhesives under 3 enamel surface conditions: (1) dry (2) saliva-contaminated (3) saliva and blood-contaminated. The shear bond strength was tested using Universal Strength Tester Autograph Shimadzu Corp. There was no significant difference in the shear bond strength between dry, saliva, and saliva-blood contamination bonded with MIP combined Transbond XT. There were significant differences in the shear bond strengths between dry and saliva -blood contaminated enamel bonded with Fuji Ortho LC. In conclusion, Fuji Ortho LC is not recommended for clinical bonding application under saliva-blood contaminated enamel conditions.
