The Effect of Conditioning on Adhesion to Human Dentin *

The Journal of Adhesion, 1994
Abstract The effect of conditioning dentin was investigated using ethyleneglycol bis(aminoethylether) tetraacetic acid (EGTA) and three proprietary agents containing ethylenediamine tetraacetic acid (EDTA), maleic acid and dipentaerythritol pentaacrylate phsophoric acid ester (PENTA).

Microleakage of Dentin Adhesive Systems

Journal of Esthetic and Restorative Dentistry, 1991
Five different dentin adhesives were evaluated under various experimental conditions (using different restorative materials, placement techniques, and specimen storage). A silver‐staining technique was used to detect microleakage. Pentra Bond II was less effective than Tenure in prevention of marginal leakage, but similar to Scotchbond 2 and Gluma.

Adhesion between collagen depleted dentin and dentin adhesives.

American journal of dentistry, 1998
To determine the influence of sodium hypochlorite treatment of dentin on shear bond strength and morphology.Shear bond strengths of several dentin bonding agents were compared following specific surface treatments that included manufacturer's directions, etching plus sodium hypochlorite, and sodium hypochlorite alone.

Dentin/Adhesive Interface in Teeth

2012
Clinical studies have demonstrated an alarmingly high failure rate for posterior composite dental restorations. The premature failure of moderate-to-large composite restorations can be traced to a breakdown of the bond at the tooth surface/composite material interface and increased levels of cariogenic bacteria at the perimeter of these materials.

Human dentin and the dentin-resin adhesive interface

Acta Materialia, 1998
Dentin, the inner hard tissue of teeth, is a complex hydrated composite and forms the substrate for much of restorative dentistry. Current efforts to improve restorative and preventive dentistry involve the development of effective bonds to this tissue.

[Dentin adhesives].

Den Norske tannlaegeforenings tidende, 1990
Chemical adhesion of resin based restorative materials to dentin using adhesives presents a complex problem due to the different nature of polymeric materials and tooth substance. It is indicated that the problems arise mainly from properties of the filling material, eg polymerization shrinkage.

[Dentin adhesives. An update].

Minerva stomatologica, 1992
Even if mechanical bonding to enamel utilizing the acid-etch technique has been very successful, adhesion to dentin is still a challenge to researchers and clinicians. Dentin is a vital tissue and differs in composition from enamel: acid-etching does not enhance the bond strength of composite resins to dentin and may elicit a severe pulpal response ...

Adhesion to enamel and dentin.

American journal of dentistry, 1990
The physical and chemical properties of restorative materials and procedures that influence the extent of microleakage at the tooth/restoration interface are discussed. Adhesion to enamel is achieved and microleakage at the enamel/restoration interface has been controlled by acid etching enamel surfaces with orthophosphoric acid. The acid concentration

Advances in dentin adhesion.

Compendium of continuing education in dentistry (Jamesburg, N.J. : 1995), 2004
While bonding to enamel has been a dependable technique, bonding to dentin is still an overwhelming task--dentin is a naturally soaked organic tissue. The enamel bonding agents of the 1960s and 1970s progressively evolved into complex multibottle or universal adhesives in the early 1990s.

[Dentin-dentinal adhesive interaction. Calorimetric measurement].

Dental Cadmos, 1990
Among the tests employed to evaluate the bond strength between dentine and dental adhesives (tensile or shear bond strength measurements, marginal leakage measurements) a general accordance on their reliability cannot be found. Calorimetric measurement may be useful in deciding if the adhesion is mechanical or chemical.
