“…Regarding the conventional composite possible eluting substances are the residual monomers of the matrix: BisGMA, BisEMA, and TEGDMA besides photoinitiator, pigments and further additives [50]. Residual monomers are suspected, for example, of causing allergies and hypersensitivities in patients or of having cytotoxic, mutagenic and estrogenic effects on cells [52][53][54][55][56]. The cytotoxic effect varies depending on the monomer type, and Kraus et al [57] observed that the cytotoxic effect of BisGMA is more pronounced than that of TEGDMA on osteoblast-like cells.…”

With the aim to design bioactive dental restorative material, the present study investigated the influence of the antimicrobial agents chlorhexidine diacetate (CHX) and octinidine (di)hydrochloride (ODH) when incorporated in two different materials. Selected parameters were polymerization enthalpy, short‐term drug release, and the effect on Streptococcus mutans as well as human gingival fibroblasts. Samples were made by mixing a nano‐hybrid ormocer (O) and a methacrylate‐based nano‐hybrid composite (C), each with a mass fraction of 2% CHX or ODH. Release profiles and concentrations of active agents from the resins were assessed, and the cell proliferation of human gingival fibroblasts as well as Streptococcus mutans cultured with the eluates were evaluated. The influence on polymerization was assessed by means of differential scanning calorimetry. Both drugs, especially ODH, showed a decreasing effect on polymerization enthalpies associated with a lowered crosslinking degree. At the same time ODH appeared to be released more persistently than CHX. Moreover, ODH was more efficient with regard to bacteria growth inhibition but also more cytotoxic in terms of reduction of cell viability. ODH is deemed more appropriate for application in a dental resin‐based drug delivery system, because of the more persistent drug release than seen for CHX.

“…The elution of non-crosslinked components from dental resin-based materials into saliva and thus potentially into the system of the human body is a critical factor in the development and application of these materials. Residual monomers are suspected, for example, of causing allergies and hypersensitivities [ 8 ] in patients or of having cytotoxic, mutagenic and estrogenic effects on cells [ 8 – 12 ]. The extent of the elution depends, for instance, on the elution medium, mechanical stress, aging, hydrolysis or enzymatic degradation [ 13 – 16 ].…”

The aim of this work was to investigate the elution of residual monomers as a function of the manufacturing process, which are CAD/CAM manufacturing, self-curing and 3D printing. The experimental materials used consisted of the base monomers TEGDMA, Bis-GMA and Bis-EMA and 50 wt.% fillers. Additionally, a 3D printing resin without fillers was tested. The elution of the base monomers into the different media (water, ethanol and ethanol/water (75/25 vol. %)) at 37 °C over a period of up to 120 d as well as the degree of conversion (DC) by FTIR were investigated. No monomer elution could be detected in water. Most residual monomers in both other media were released from the self-curing material whereas the 3D printing composite released relatively little. The CAD/CAM blanks released hardly any quantitatively detectable amounts of monomers. Relative to the base composition, TEGDMA eluted less than Bis-GMA and Bis-EMA. DC did not correlate with residual monomer release; thus, leaching was determined not only by the amount of residual monomers present but by further factors as possibly network density and structure. The CAD/CAM blanks and the 3D printing composite showed similar high DC but lower residual monomer release from the CAD/CAM blank, likewise the self-curing composite and the 3D printing resin exhibited similar DC but different monomer elution. In terms of residual monomer elution and DC, the 3D printing composite seems promising as a new material class for the use as temporary dental crowns and bridges. Graphical Abstract

“…Incomplete polymerization can cause tissue irritation. Kostic.et al, 2018 (53) and Mesquita et al, 2017 (54) revealed that monomer initiated inflammation in subcutaneous tissue-layer. Even the toxic could be subsided, but the inflammation continued for period.…”

This study evaluated the effect of ultrasonic treatment and surface treatments on transverse strength of denture bases which relined with auto-polymerizing acrylic resin. The study groups, ninety heat-polymerized acrylic resins (64×10×2 mm) were divided by three surface treatments: no surface treatment (N), applied MMA for 180 seconds (MM), applied MF-MA for 15 seconds (MF). They were relined with auto-polymerized acrylic resin to create 64×10×3.3 mm specimens. Then, they were divided further by ultrasonic which were no ultrasonic (X), ultrasonic in water (W), ultrasonic in 30% ethanol (E). As a result, all test groups were classified as NX, NW, NE, MMX, MMW, MME, MFX, MFW, MFE (n=10). All samples were performed three-point bending test. Two-way ANOVA presented that there was an interaction between ultrasonic and surface treatments. Then One-way ANOVA was analyzed. Ultrasonic could increase transverse strength of all relined specimens (p<0.05). Ultrasonic in ethanol increased strength superior to water (p<0.05) and presented the highest mean strength. In the same ultrasonic treatment, MMA and MF-MA increased the transverse strength of relined denture bases compared with no applying groups (N) (p<0.05). There was no difference between all MM and MF groups (p>0.05).
