“…This elution of unreacted monomers during the immersion in water period, results in mass loss and is calculated as solubility. In this study, solubility of the cement under three activation protocols was not significantly different and presented low levels (≤0.1%), even lower than some reported in the literature 12,21 . The average values of water sorption and solubility of the resin cement RelyX U200 for the three tested polymerization protocols were lower than 40 μg/mm 3 and 7.5 μg/mm 3 , respectively 20 .…”

“…According to Marghalani (2012), the percentage of the mass variation or the weight increase of the specimen by absorption of water does not include the free monomers, which are not bonded to the polymer chain and are eliminated simultaneously in water absorption, resulting in reduced mass of the specimen 21 . It was suggested that the structural parameters of the polymers that affect sorption and solubility are crosslinking density and porosity of the polymer chains 25 .…”

“…The greater density of inorganic filler reduces sorption 18 , but the reaction between filler particles and water can also promote water retention 5 . The sorption and release of residual monomers are related to the degree of polymerization, the composition of the material: organic matrix and filler particles; and also the solvents used for in vitro studies 5,21,[25][26][27] . Among the factors that affect the hygroscopic and hydrolytic properties of the cements, the degree of polymerization is linked to the sorption, solubility, hydrolytic degradation and the formed polymer, because the quality of the network formed by polymerization regulates the solvent sorption and expansion of the material 18 .…”

“…The high water sorption and solubility influence negatively the resinous materials, indicating lower chemical stability, lower biocompatibility, higher expansion and lower mechanical properties. Sorption, solubility and mass variation are considered indicators of the chemical, physical and mechanical properties observed in the structure of the polymeric network 12,21 . Alterations of these properties can lead to deleterious clinical effects.…”

“…The expansion resulting from water sorption favours the release of the monomers not linked into chains, reduction of mechanical properties 18 and the cement plasticisation can generate unsupported areas, causing fracture to indirect restorations 19 . Sorption and solubility tests are used for in vitro evaluation of resin-based materials 20 , including dual-cured resin cements 12 , to evaluate and recommend the materials with lower sorption and solubility for indirect restorations 21 . The water absorption measured by sorption, influences negatively the material, causing expansion, weakening of matrix and filler bonding, discoloration and reduction of mechanical properties 20 .…”

Aim: To evaluate the effect of different activation protocols on the polymerization of a self-adhesive dual cured resin-based cement. Methods: Thirty disc-shaped specimens were prepared with the resin cement RelyX U200 (3M ESPE) and divided according to three protocols: immediate light-activation for 40 s, delayed light-activation (10 min after manipulation, for 40 s) or self-curing without lightactivation. The specimens were desiccated, kept in water at 37 °C for 7 days and desiccated again to calculate water sorption, solubility and mass variation. Data were analyzed by Shapiro-Wilk Test and Wilcoxon tests (α=0.05). Images after the specimens' final desiccation were also made. Results: The Wilcoxon test revealed a significant difference for sorption and mass variation (p<0.05) and the highest value was observed in self-curing or chemical activation group (CA), followed by delayed light-activation (DL) and immediate light-activation (IL). Besides the water sorption parameters, there were also microvoids on the discs from the delayed and no light-activation groups. Conclusions: The light-activation immediately after manipulation is recommended for the evaluated resin cement.

The aim of this study was to evaluate radiographically and histologically the pulpal and periapical response to self-adhesive (Rely X™ Unicem) and self-etching and self-curing (Multilink(®)) resin-based luting materials in deep cavities in dogs' teeth. Deep class V cavities (0.5-mm-thick dentin) were prepared in 60 canine premolars and the following materials were applied on cavity floor: Groups I/V-RelyX™ Unicem; Groups II/VI-Multilink(®); Groups III/VII-zinc phosphate cement (control) and; Groups IV/VIII-gutta-percha (control). Cavities were restored with silver amalgam. Animals were euthanized after 10 days (groups I-IV) and 90 days (groups V-VIII). Tooth/bone blocks were radiographed and processed for histopathological evaluation of pulp and periapical tissue response to the materials. All materials presented similar histopathological features and radiographic findings at both periods. The pulp tissue was intact. The apical and periapical regions and periodontal ligament thickness were normal. No inflammatory cells, resorption of mineralized tissue (dentin, cementum, and alveolar bone) or bacteria were observed. The lamina dura was intact and no areas of periapical bone rarefaction or internal/external root resorption were observed radiographically. It can be concluded that Rely X™ Unicem and Multilink(®) caused no adverse tissue reactions and may be indicated for cementation of indirect restorations in deep dentin cavities without pulp exposure.
