“…McCabe et al [ 15 ] stipulated that, when compared to other materials, giomers tend to absorb more water—due to the osmotic effect generated by the presence of poly-acidic area inside the pre-reacted glass filler in the resin matrix. In another study, EL-Sharkawy et al observed that water sorption has a significant influence on the color and marginal seal of the direct resin-based restoration [ 5 , 16 , 17 ]. At the same time, the functional particles, hydroxyl, carboxyl, and phosphate tend to bind to water by hydrogen bonds, further leading to inflating and plasticizing the polymer resin matrix [ 18 , 19 ].…”

“…Heterogeneity in the matrix allows larger micro-pores to be formed between polymers, leading to a significantly higher water sorption. These characteristics might explain the predisposition to absorb water that TEDGMA-based materials exhibit [ 5 ]. High water sorption values of giomer materials can be further explained by the acid–base reaction that takes place [ 20 ].…”

“…Distilled water was found to increase the surface roughness in relation to the water sorption and solubility process [ 5 ]. After 30 days of exposure, the samples are affected in a similar manner.…”

“…Commercially, giomers have been introduced on the market by Shofu Dental (Japan) which provided different consistencies, adapted for various clinical situations: conventional (indicated for reconstruction of tooth anatomy when important portions of the dental structure are missing) and flowable giomers, with more specific indications, according to their individual consistencies: high stress areas, like class V restorations, or marginal ridges, cavity liners, and small restorations [ 3 , 4 , 5 , 6 ].…”

“…This complex process is influenced by the quantity of the residual monomer as consequence of the polymerization process, elutable components, type of solvent and the composition of the leached material. It is therefore necessary to thoroughly investigate the sorption and solubility of a resin-based material, given the influence these can have on the stability and performance of the restoration over time [ 4 , 5 , 11 ].…”

The objective of this study is the characterization of a novel experimental flowable giomer (G) regarding water sorption, water solubility, and the microstructural characteristics, in comparison to three commercial giomers: Beautifil flow Plus X F00 (B-F00), Beautifil flow F02 (B-F02) and Beautifil flow Plus X F03 (B-F03), Shofu, Kyoto, Japan. Methods: Water sorption/solubility was performed by weighing the specimens before and after water immersion for 1, 2, 3, 14, 21 and 30 days. Data analysis was carried out with the software Origin2019b Graphing & Analysis using the ANOVA test and the Tukey test for post hoc comparison of the groups of materials. The microstructural analyses were done with a scanning electron microscope (SEM) and an atomic force microscope (AFM). The results showed significant differences between the tested materials (p < 0.05). For sorption, the Tukey test indicated differences between all four sample groups, except between B-F02 and B-F03, which exhibited no differences in any of the investigation days. The Tukey test also showed significant differences regarding solubility between all sample groups in the 30-day interval. SEM images and roughness showed that after 30 days of immersion in water, the experimental giomer G had the roughest surface.

Introduction: Giomer is a resin-based restorative material consisting of prereacted glass ionomer (PRG) filler which can release fluoride. Carbonated beverages, popular beverages which contain acids that rich in H+ ions, can diffuse into the resin-based restoration and cause high solubility. Objective: To analyze the effect of immersion in carbonated drinks on water absorption and diametral tensile strength of giomer. Methods: Giomer was packed into a stainless-steel mold to obtain sample with diameter of 6.0±0.03mm and height of 3.0±0.09mm. The samples were divided into 2 groups for water absorption test and 3 groups for diametrical tensile strength test. Ten samples of giomer were soaked in artificial saliva for 4 days as a control group, 10 giomer samples were immersed in carbonated drinks for 6 hours, then replaced with artificial saliva for 18 hours and repeated for 4 days as a treatment group, and 10 samples of giomer were used as immediate group for direct diametral tensile strength test. Samples were incubated at 37°C. Results: Mann-Whitney test showed no significant difference (p>0.05) in giomer absorption between the control group (0.99±0.54%) and the treatment group (2.37±2.62%). One Way ANOVA test showed significant difference (p<0.05) in giomer diametral tensile strength among the immediate group (29.6±3.7MPa), the control group (51.1±3.9MPa) and the treatment group (44.8±5.3MPa). Conclusion: Immersion in carbonated beverages did not show significant difference with artificial saliva for the water absorption ability of giomer. However, the diametral tensile strength of giomer decreased after immersion in carbonated beverages for 24 hours.
