Bond strength of adhesive systems to human tooth enamel
Shear strength Dentin-bonding agents Dental enamel
2009/10/16
The purpose of this study was to evaluate in vitro three adhesive systems: a total etching single-component system (G1 Prime & Bond 2.1), a self-etching primer (G2 Clearfil SE Bond), and a self-etchin...
This in vitro study evaluated the effectiveness of whitening dentifrices for the removal of extrinsic tooth stains. Twenty dental blocks (4 x 4 mm), including enamel and dentine, removed from freshly ...
Effect of Adhesive Primer Developed Exclusively for Heat-curing Resin on Adhesive Strength between Plastic Artificial Tooth and Acrylic Denture Base Resin
Adhesive primer Adhesion Artificial tooth
2009/9/14
Despite progress in the development of denture base resin and artificial tooth materials, dental clinics are still plagued with artificial teeth falling off the denture base - due to poor bond strengt...
Shear Bond Strength of Tooth-colored Indirect Restorations Bonded to Mid-coronal and Cervical Dentin
Resin inlay Resin cement Cervical dentin Micro-shear bond strength
2009/9/14
To investigate the bonding of tooth-colored indirect restorations to cervical dentin, shear bond strengths of bonded resin inlays to cervical dentin and mid-coronal dentin were investigated and compar...
Development of Three-dimensional FE Modeling System from the Limited Cone Beam CT Images for Orthodontic Tipping Tooth Movement
Three-dimensional FE model Orthodontic tooth movement Limited cone beam CT
2009/9/14
Previously, numerous three-dimensional finite element (FE) models of the dentoalveolar complex have been developed and stress analyses of orthodontic tooth movements were reported. Most of the models ...
