Opis

The following conclusions are drawn from this comparative in-vitro study on the shear bond strength and debonding characters of Transbond XT, Esthet-X Flow and Filtek Z-350 using metal brackets Filtek Z-350 has a comparable mean bond strength value (11.07+/-1.03 MPa) like that of Transbond XT (11.58+/-1.3 MPa). Esthet-X Flow has slightly lower mean bond strength value (10.70+/-2.0 MPa) compared Filtek Z-350 and Transbond XT. All the three adhesives exhibited clinically acceptable bond strength. 60-70% of all the three adhesives exhibited cohesive type of bond failure. The efficacy of the flowable composites as a bonding agent needs invivo and clinical assessment through a survival analysis. Filtek Z-350 and Esthet-X flow exhibited problems with handling properties and flowability. Drifting of brackets was noted and pressure was needed for positioning the bracket with Filtek Z-350 and Esthet-X flow. The flow property and viscosity should be balanced to obtain optimal consistency to achieve optimal bond strength and improve handling property for Filtek Z-350 and Esthet-X flow.
