Shear bond strength of orthodontic brackets to aged resin composite surfaces: effect of surface conditioning.
The aim of this study was to investigate the effects of surface conditioning protocols on the shear bond strength (SBS) of metal brackets to aged composite resin surfaces in vitro. Ninety composite resin discs, 6 mm in diameter and 2 mm in height, were prepared and treated with an ageing procedure. After ageing, the specimens were randomly assigned to one of the following groups: (1) control wi...
متن کاملEffect of Bleaching on Shear Bond Strength of Orthodontic Brackets
The purpose of this in vitro study was to determine the effect of bleaching on shear bond strength of orthodontic brackets. This randomized control trial was performed over a period of 6 months in the department of orthodontics, de,Montmorency College of Dentistry, Lahore. A total of one hundred and forty extracted premolar teeth were included which were further divided into two groups. Group A...
متن کاملShear Bond Strength of Orthodontic Brackets to Tooth Enamel After Treatment With Different Tooth Bleaching Methods
BACKGROUND Bleaching treatments decrease shear bond strength between orthodontic brackets and teeth; although definite results have not been reported in this regard. OBJECTIVES This study determined the effects of different bleaching protocols on the shear bond strength of orthodontic brackets to teeth. MATERIALS AND METHODS This experimental study was performed in Iran. Forty-eight extract...
متن کاملEffect of surface treatment of prefabricated teeth on shear bond strength of orthodontic brackets
Objective: The aim of this in vitro study was to evaluate and compare the effects of grinding, drilling, sandblasting, and ageing prefabricated teeth (PfT) on the shear bond strength (SBS) of orthodontic brackets, as well as the effects of surface treatments on the adhesive remnant index (ARI). Methods: One-hundred-ninety-two PfT were divided into four groups (n = 48): Group 1, no surface tre...
متن کاملEffect of Four Methods of Surface Treatment on Shear Bond Strength of Orthodontic Brackets to Zirconium
OBJECTIVES Providing reliable attachment between bracket base and zirconia surface is a prerequisite for exertion of orthodontic force. The purpose of the present study was to evaluate the effect of four zirconium surface treatment methods on shear bond strength (SBS) of orthodontic brackets. MATERIALS AND METHODS One block of zirconium was trimmed into four zirconium surfaces, which served a...
