“…Indeed, both monomers are reported to be highly cytotoxic in primary and immortal cell cultures, such as fibroblasts derived from the human pulp, periodontal ligament or gingiva 28) . Polydorou et al 16) investigated the degree of polymerization by analyzing monomers with curing times ranging from 0 to 80 s. Price et al 19) investigated the Knoop hardness of composite resins after curing at different distances. We measured the amounts of unreacted monomers using two hybrid types and two flowable types of resins to find the optimal curing time and distance in a bid to minimize the release of harmful substances.…”

“…The amounts of monomers released from commercial dental resins under different polymerization conditions (e.g., light source, curing intensity) have been principally investigated using HPLC-UV [12][13][14] or HPLC-mass spectrometry 15,16) . The safe use of composite resins with aesthetically pleasing results is dependent on several factors such as light wavelength 17) , exposure time 18) , distance from light guide exit 19) , light source 13) , and light intensity 20) .…”

The aim of this study was to analyze the unreacted monomers of four commonly used composite resins, which were released after curing with different polymerization conditions. Four composite resins, consisting of two hybrid types and two flowable types from two manufacturers, were photopolymerized using different curing times and curing distances. After polymerization, samples were extracted for analysis at different time points up to 24 h. Released monomers were analyzed by reversed-phase liquid chromatography at UV 210 nm. Longer curing times and shorter curing distances resulted in higher polymerization rates and decreased release of TEGDMA and UDMA, but changes in curing time and distance had no significant effect on Bis-GMA. Release of BPA increased with increase in curing time or decrease in curing distance, in contrast to the results of TEGDMA and UDMA. Polymerization conditions need to be differently applied according to both monomer and resin types.

“…It has been reported that the type of light curing unit and light parameters such as light spectrum and intensity afect the cytotoxic properties of dental adhesives, as well as polymerization time and application mode [66,3]. "ll these parameters inluence directly the degree of monomer conversion and consequently the release of residual monomers.…”

“…The determinant factor of the death was the monomer concentration, given that low concentrations of "is-GM" induced apoptosis, whereas high concentrations induced death by necrosis or late apoptosis. "is-GM" dissolves easily and may cause irritation or a lichenoid reaction of the oral mucosa in close and prolonged contact with gingival tissues, especially after cervical illing procedures [12,66]. TEGDM" is a copolymer used in major recent biomaterials with resin phase as a diluent.…”

The accomplishment of developing a truly adhesive bond between a restorative material and the natural tooth structures is the goal of adhesive dentistry. Dentine adhesive systems come into close contact with dental and oral tissue, especially the pulp and gingival cells. Due to this close and long-term contact, adhesives should exhibit a high degree of biocompatibility. "iocompatibility is one of the most important properties of dental materials, and adhesives are no exception. It has been long demonstrated that diferent components of adhesives can be released. Numerous in vitro investigations have shown that released monomers and other components can cause damage to cultured cells. In addition, many in vivo studies have shown that uncured components which reach the pulpal space cause inlammatory response and tissue disorganization. Only a combination of various in vitro and in vivo tests can provide an overview of the interaction of biomaterials with the host. Therefore, it is necessary on a regular basis to carry out and re-verify the biological compatibility of the increasing number of new dental materials. "dhesives should be biofunctional, protective, and preventive, with health-promoting efects that contribute to a beter prognosis for restorative treatments and its biocompatibility.

“…The release may remain on a high level for some days (Polydorou et al 2007). In addition, as noted above, chemical, microbiological and wear impacts are observed over time, and occlusal or approximal degradation of composites restorations occurs (Groger et al 2006, Söderholm 2003.…”
