Bond Strength of Orthodontic Adhesives
The objective of this study was to evaluate and compare bond strength of four adhesives used in orthodontics for bonding brackets to tooth enamel. The adhesives used in this investigation were resin-reinforced glass-ionomer cement (Fuji Ortho LC-GC Corporation, Japan), light cured composite resin adhesives (ConTec LC-Dentaurum, Germany and Enlight Bonding system-Ormco, USA) and dual cured compo...
متن کاملBacterial adhesion of Streptococcus mutans to orthodontic adhesives with various filler-volume fractions.
INTRODUCTION The aim of this in-vitro study was to investigate the effect of the filler-volume fraction of experimental composite adhesives on the bacterial adhesion of Streptococcus mutans. METHODS Three experimental adhesive groups were created: an unfilled urethane-dimethacrylate (UDMA) adhesive, UDMA and a filler-volume fraction of 35%, and UDMA and a filler-volume fraction of 70%. The em...
متن کاملPolymerization of the Dental Adhesives
Objective: The bonding adhesive holds the composite filling to the residual tooth, creating a chain cross-–link during the photo polymerization process. In this article we will be discussing the polymerization process under a thermodynamic viewpoint between amorphous structures of the dental market adhesives, the hybrid layer of the residual tooth and the white polymers filling. The thermodynam...
متن کاملConventional and high-intensity halogen light effects on polymerization shrinkage of orthodontic adhesives.
The objectives of this study were to compare the polymerization shrinkage of three orthodontic adhesives. In addition we wanted to determine the effectiveness of the high-intensity quartz tungsten halogen (HQTH) in curing orthodontic adhesives on polymerization shrinkage with that of the quartz tungsten halogen (QTH). A total of 120 glass ring molds were prepared using a low-speed saw. The inte...
متن کاملEvaluation of Cytotoxicity and Degree of Conversion of Orthodontic Adhesives over Different Time Periods
As new orthodontic resin adhesives continue to be marketed, rapid and sensitive tests for examining their toxic effects at the ‘ cell and tissue level ’ are needed because patient safety has been identifi ed as a legal concept. The objective of the present study was to evaluate the cytotoxicity and degree of monomer conversion of orthodontic adhesives over different time periods. Seven adhesive...
