TL;DR: The water absorption characteristics of resins, upon which many composite filling materials are based, have been studied and it is found that the equilibrium uptake is less than that predicted from the water absorption of composite fill materials, if it is assumed that the polymer alone absorbs the water.

Hygroscopic and hydrolytic effects in dental polymer networks.
TL;DR: Dental polymer networks have been shown to be susceptible to hygroscopic and hydrolytic effects to varying extents dependent upon their chemistry and structure, and these effects on the clinical performance of polymer restoratives is largely unknown.

Water sorption and solubility of dental composites and identification of monomers released in an aqueous environment
TL;DR: Water sorption and solubility of six proprietary composite resin materials were assessed, and monomers eluted from the organic matrix during water storage identified, and triethyleneglycol dimethacrylate was the main monomer released.

Biodegradation of resin composites and adhesives by oral bacteria and saliva: a rationale for new material designs that consider the clinical environment and treatment challenges.
TL;DR: The field's current understanding of resin biodegradation in the oral cavity is just beginning to grasp the role of bacteria and enzymes in the failure of resin-based restorations, and the literature provides strong support that together, the above factors can breakdown the marginal interface and limit the longevity of resin composite restoration.

Water sorption and solubility of resin-based materials following inadequate polymerization by a visible-light curing system.
G. J. Pearson,C. M. Longman +1 more
TL;DR: The water sorption and solubility of three hybrid and one microfine composite are reported, with marked increased in both parameters, which will have clinical significance on the durability of the material.

The influence of resin chemistry on a dental composite's biodegradation.
Y. Finer,J. P. Santerre +1 more
TL;DR: Because both systems were identical except for their monomer systems, it was concluded that changes in biostability were associated with chemistry.

TL;DR: Water absorption characteristics have been studied in terms of diffusion coefficient, equilibrium uptake, and solubility as a function of the volume loading of pyrolytic silica filler, for two different resins.

The sorption and diffusion of water in silicone rubbers: Part I. Unfilled rubbers
J. A. Barrie,D. Machin +1 more
TL;DR: In this article, the authors measured the equilibrium sorption, permeation, and sorption kinetic measurements for water in polydimethylsiloxane rubbers containing various amounts of either sodium chloride or silica filler, and interpreted the results in terms of a model in which a fraction of the water sorbed is immobilized by the filler or by the formation of salt solution.

Water Absorption of Some Denture Base Polymers
G.D. Stafford,Michael Braden +1 more
TL;DR: The absorption of water by denture base polymers is of considerable importance since it is accompanied by dimensional changes and the rate at which water is absorbed, and hence the time to equilibrate, is governed by a physical parameter known as the diffusion coefficient.

Hydrolytic degradation of dental composites and effects of silane-treatment and filler fraction on compressive strength and thermal expansion of composites
Karl-Johan M. Söderholm
- 01 Jan 1984
TL;DR: In this paper, the weakest link of dental composites is the filler-matrix bond, due to incompleteness of information dealing with this bond and its stability in a hum...

Diffusion of Water in Composite Filling Materials
TL;DR: Although most materials showed reversible behavior during repeated sorption-desorption cycles, one material showed irreversible breakdown, with the magnitude of the diffusion coefficients consistent with diffusion occurring in the resin phase.
