Composite resins Physical properties Tensile strength
2009/10/19
The aim of this study was to evaluate the diametral tensile strength (DTS) of composite resins submitted to different curing techniques. Four composite resins were tested in this study: Targis (Ivocla...
Flexural and diametral tensile strength of composite resins
Composite resins Tensile strength Physical properties
2009/10/16
This study evaluated the flexural strength (sf) and the diametral tensile strength (st) of light-cured composite resins, testing the hypothesis that there is a positive relation between these properti...

Flat rectangular tabs (n=270) prepared from spherical (Tytin), admixed (Dispersalloy) or lathe-cut amalgam (ANA 2000) were subjected to aluminum oxide sandblasting with either 50-µ or 90-&mi...
Combinations of etchants, composite resins, and bracket systems:An important choice in orthodontic bonding procedures
Orthodontic bonding Acid concentrations
2009/1/7
The objectives of this investigation were: (1) to compare the shear bond strengths (SBS) of metal, ceramic, and plastic brackets using different concentrations of maleic and phosphoric acid gels and...
In Vitro Evaluation of Shear Bond Strengths and In Vivo Analysis of Bond Survival of Indirect-Bonding Resins
Indirect bonding Shear bond strength In vivo bond survival
2008/12/12
In this study we evaluate the shear bond strengths (SBS) of indirect-bonding systems available on the market. For the in vitro study, 60 extracted premolars were divided into three groups. In indi...
Color alteration of adhesive during treatment and after debonding may be implicated in long- term enamel discoloration. The aim of this study was to assess the color stability of light-cured and c...
