The effect of enamel preparation on the tensile bond strength of orthodontic composite resin
Tensile bond strength Orthodontic brackets Air-powder polisher Enamel surface preparation Sodium bicarbonate residue Orthodontic composite resin
2009/1/13
The bonding of orthodontic brackets to enamel surface using bis-GMA composite resin is usually accomplished by first cleaning the tooth surface then etching with phosphoric acid. This study compar...
Sealant and resin viscosity and their influence on the formation of resin tags
Bonding Resin Sealant Tags
2009/1/12
The ability of resin to penetrate tooth enamel during orthodontic bonding may be affected by the viscosity of the resin and the presence of a sealant. Twenty-four extracted molars were randomly di...
Orthodontic resin under water immersion
Bond strength Debonding interface Orthodontic resin Water immersion
