Modifications of Glass Ionomer Cements Using Nanotechnology: Recent Advances

Glass ionomer cements (GICs) are dental materials that were invented by Wilson & Kent in 1972. They can chemically bond to enamel and dentin exhibit anti-cariogenic activity allows the release uptake of fluoride ions. also possess ability render color. The setting reaction GICs is a neutralization results formation polycarboxylate salts. most important GIC modification process involves addition resin components, resulting development resin-modified glass (RMGICs), which contain self-and photo-curing systems. Modification conventional RMGICs be achieved incorporation nano-sized fillers into materials. This helps reduce size RMGICs. Conventional modified introducing bioceramics powder. It has been previously reported particles improve mechanical properties GICs. Conversely, commercially available nano-filled do not hold any significant advantage over as far adhesive concerned. carbomer novel material, bioactivity better than However, it more brittle less strong modern Additionally, clinical techniques used transfer external energy on surface have for modification. These duration initial stage rate reactions, faster properties. Premature failure restorations avoided under these conditions. lack long-term studies limits use nano-modified ionomers carbomers daily practice. More randomized trials required justify
