Health hazard from resin-modified glass ionomer materials in pediatric dentistry. -

Resin-modified glass ionomer fillings are commonly used in pediatric dentistry. We have investigated possible exposure of monomers from such materials in vivo. Saliva was collected at three time points, pre-treatment, immediately after placement, and one week post-placement, from 20 patients aged seven to ten that had their first resin-based glass ionomer filling placed.

Effect of polymerization temperature and time on the residual monomer content of denture base polymers. -

The polymerization temperature and polymerization time considerably affect the residual MMA content of denture base polymers.
