“…A thin film system would exhibit an adequate photopolymerization as the thin film had little shield on light. It indicated that the migration stability of TX‐EA and TX‐BDA was enhanced in comparison to that of TX‐PA, especially TX‐BDA, which would have great potential applications in food packing or biomedical fields . Therefore, the more aminoalkyl groups and acryloxy groups may lead to lower extractability in the solidified resin.…”

Two thioxanthone based acrylated one‐component visible light photoinitiators, 2‐(methyl(4‐((methyl(9‐oxo‐9H‐thioxanthen‐2‐yl)amino)methyl)benzyl)amino)ethyl acrylate (TX‐EA) and ((4‐((methyl(9‐oxo‐9H‐thioxanthen‐2‐yl)amino)methyl)benzyl)azanediyl)bis(ethane‐2,1‐diyl)diacrylate (TX‐BDA), are designed and synthesized. The results of photopolymerization and migration study demonstrate that TX‐EA and TX‐BDA are more effective one‐component visible light photoinitiators for free radical polymerization with excellent migration stability than 4‐((methyl(9‐oxo‐9H‐thioxanthen‐2‐yl)amino)methyl)phenyl acrylate. The mass fraction of the extracted TX‐BDA in a cured 1,6‐hexanediol diacrylate polymer film is as low as 0.55% and the residual amount is estimated to be only 90 ppm. TX‐BDA would have great potential to be used in visible light curing systems, particularly in the food packing or biomedical fields. Results demonstrate that the synergistic effect of hydrogen donors and polymerizable groups in photoinitiator plays an important role in realizing high performance and low migration in photopolymerization system.

“…Camphorquinone (1,7,7 -trimethylbicyclo [2.2.1] heptane -2,3 -dione, CQ) belongs to the aliphatic α-diketones and is by far the most widely used photoinitiator for visible-light photocrosslinking in methacrylate-based dental restorative polymers and other biomedical applications (8)(9)(10). CQ absorbs light in the UV-region at 200-300 nm and in the visible light region at 467 nm (responsible for its yellow color) (11).…”

“…However, the chromosomal and genetic instability of exposed cells remains a concern when UV light is utilized [111, 112]. Visible light induced photopolymerization has been proposed for more biocompatible photopolymerization systems, which include camphorquinone [113], eosin-Y [114], lithium phenyl-2,4,6-trimethylbenzoylphosphinate [115], riboflavin [116], ruthenium/sodium persulfate [117] and Rose Bengal [118]. The photo-polymerization method exhibits multiple advantages, such as fast solidification, both spatial and temporal control over the solidification to form uniform hydrogels, and no requirement of high temperatures or extreme pH values.…”

Injectable scaffolds are appealing for tissue regeneration because they offer many advantages over pre-formed scaffolds. This article provides a comprehensive review of the injectable scaffolds currently being investigated for dental and craniofacial tissue regeneration. First, we provide an overview of injectable scaffolding materials, including natural, synthetic, and composite biomaterials. Next, we discuss a variety of characteristic parameters and gelation mechanisms of the injectable scaffolds. The advanced injectable scaffolding systems developed in recent years are then illustrated. Furthermore, we summarize the applications of the injectable scaffolds for the regeneration of dental and craniofacial tissues that include pulp, dentin, periodontal ligament, temporomandibular joint, and alveolar bone. Finally, our perspectives on the injectable scaffolds for dental and craniofacial tissue regeneration are offered as signposts for the future advancement of this field.
