AIM: The aim of this study was to compare the shear bond strength of two techniques for bonding lingual orthodontic retainer; the chairside modified bonding technique introduced by Al-Emran and Hashim, and the chairside manual bonding technique currently used in orthodontic practice. MATERIALS AND METHODS: Sixty-four extracted cariesfree premolars were divided into two equal groups. Group A rep...

objective: the purpose of the study was to evaluate the influence of adding nanofiller particles to a dentin bonding agent on resin-dentin bond strength. materials and methods: fifty-four human intact premolar teeth were divided in to 6 groups of nine. the teeth were ground on occlusal surfaces and polished with 320 and then 600 grit silicon carbide papers. an experimental bonding system based ...

The aim of this study is to “evaluate the shear bond strength of immediately repaired light cured composite resin using different bonding agents”. Forty recently extracted human incisors were mounted on acrylic resin blocks and cavity (5 × 3mm) was prepared at the middle third of the crown. The prepared cavity was etched, rinsed, dried and restored using Single bond adhesive (3M), composite and...

AIM To find an alternative to popular orthodontic bonding agent composite resin and elimination of acid etching. To assess GC Fuji Ortho as an orthodontic bonding agent under different enamel conditions and evaluate the shear bond strength. Enamel surfaces intentionally contaminated with saliva, conditioned enamel using Fuji dentin conditioner and conventional 37% phosphoric acid/60 seconds. To...

Written and clinical tests compared the change in clinical knowledge and practical clinical skill of first-year dental students watching a clinical video recording of the three-step etch-and-rinse resin bonding system to those using an interactive dental video game teaching the same procedure. The research design was a randomized controlled trial with eighty first-year dental students enrolled ...

In vitro bond strengths of three resin adhesive systems were tested using 111 primary teeth. Ninety-six flat dentin surface specimens were divided into six groups consisting of 16 primed or 16 unprimed samples for each adhesive system. The remaining 15 tooth samples were divided into three groups of five to determine each adhesive system's bond strength to primary etched enamel. Resin buttons w...

The aim of this study was to compare the in vitro bond strength to enamel measured in shear of the light-activated bonding agent Heliosit-Orthodontic with the shear bond strength of the two-paste bonding resin Concise and the 'no-mix' bonding resin Right-On. In a number of separate tests involving 205 teeth and 267 bonds, the Heliosit-Orthodontic is shown to form a stronger bond to canine teeth...
