Sorption and solubility of luting cements in different solutions

Abstract

This study examined the solubility, sorption, and dimensional change of eight luting cements in two different solutions: 50% ethanol:water and distilled water. Ten disk specimens were prepared of each material following the manufacturers ' instructions, and then ground with silicone carbide paper. Sorption and solubility were calculated by weighing the specimens before and after immersion and desiccation. Data were analyzed by two-way ANOVA, Tukey ' s HSD and Fisher ' s PLSD tests. GC Fuji Plus and RelyX Luting2 showed the highest values of sorption and solubility both in water and ethanol:water. The percentage changes in volume for Maxcem, Nexus 2, Panavia F, RelyX Veneer, and VariolinkII were considerably smaller than for GC Fuji Plus, RelyX Luting2, and seT in both water and ethanol:water and after desiccation. Stability occurred within 2 weeks for all the eight materials when in water, while GC Fuji Plus, Maxcem, Panavia F and seT took 3 to 4 weeks to stabilize in ethanol:water.

Effects of curing protocols on fluid kinetics and hardness of resin cements

“…These values ranged from 0.89% to 7.32% among the different experimental groups. In a previous study 4) , in which the water sorption and solubility of a variety of commercial cements were evaluated, a similar fluid kinetics behavior was noted when the specimens were subjected to the same environment. Despite the differences in the methodology, water sorption and solubility results were found to be dependent on filler parameters such as type, size, content, and concentration.…”

“…A lower organic matrix content also helps to explain the lowest water uptake. Lower water sorption in high filler-loaded resins has previously been reported in the literature 4,35) . A highly filler-loaded composite may be more susceptible to disintegration once the matrix has degraded and a stable structure is no longer provided for the filler particles 26) .…”

“…Currently, many discussions in the literature address the degradation and leaching of monomers after simulated aging in various solvents, including saliva, water, and ethanol [1][2][3][4] . Water absorption was previously deemed beneficial to filling materials, as the consequent swelling was believed to compensate for polymerization shrinkage [5][6] .…”

Effect of adhesive hydrophobicity on microtensile bond strength of low-shrinkage silorane resin to dentin

“…20 Braden and Clarke and Mese et al reported that filler volume is also related to water sorption, which means that resins contains higher filler volumes absorb less water. 21,22 If an adhesive monomer has a polarity and a solubility which are similar to those of a polymer substrate, the monomer may act as a solvent for the polymer and may infiltrate it. If both parameters are sufficiently different, the monomer and polymer are immiscible.…”

Kinetic of water diffusion and color stability of a resin composite as a function of the curing tip distance

“…Currently, many discussions in the literature address the degradation 1 , color-change 2,3 , and leaching of monomers after simulated aging in various solvents, including saliva, water, and ethanol 4,5 . Water absorption was previously deemed beneficial to filling materials, as the consequent swelling was believed to compensate for polymerization shrinkage 6 .…”
