Effects of dentin permeability and hydration on the bond strengths of dentin bonding systems.

This in vitro study evaluated the shear bond strengths of five adhesive systems bonded to dentin with and without simulated physiologic hydrostatic pressure. To simulate pulpal pressure, bonding procedures were done on extracted teeth connected to a hydration apparatus. Bond strengths were significantly less for each adhesive system under simulated physiologic conditions. Amalgambond had significantly higher bond strengths than Clearfil Photo Bond, Gluma, Scotchbond 2, or Tenure, either with or without simulated pulpal pressure.

Effects of time after extraction and depth of dentin on resin dentin adhesives.

An adhesive shear test has proved to be reproducible and potentially usable for screening new systems. When evaluating current resin dentin adhesives, it appears that the length of time elapsed since extraction of the tooth has little effect on adhesion. Conversely, adhesion significantly decreases as the pulp is approached.

Improving bond strength through acid etching of dentin and bonding to wet dentin surfaces.

A bonding system using moisture on the tooth surface can be an enormous benefit as obtaining dentin dryness in the mouth is nearly impossible. The author describes a system that bonds to both wet and dry surfaces.

[The influence of dentin conditioning on permeability of dentin].

In this study the influence of four different pretreatments showed significant differences on the permeability of cut dentin. On the average the application of 25% polyacrylic acid increased the permeability by approximately 10 percent, the application of 34% polyacrylic acid by 30 percent. The treatment with 0.1% chlorhexidin-digluconate produced no change of permeability. Calciumhydroxide suspension reduced the permeability by 15 percent and diminished the increase caused by phosphoric acid significantly.

Factors in dentin bonding. Part 1: A review of the morphology and physiology of human dentin.

Dentin bonding has been the object of intensive research for many years. If a substance is expected to bond to a natural tooth surface, the morphologic and physiologic characteristics of the substrate determine both the bonding applications and testing methods used.
