Quantitative analysis of peroxides in restorative resins.
It has been demonstrated previously by other authors that the quantity of benzoyl-peroxide influences the properties of restorative resins. The purpose of the present work was to analyse quantitatively peroxides in commercial restorative resins. The analysis was performed by iodometric titration. Sixteen brands were investigated, and it was found that the amount of peroxide varied between 0.3% and 2.6% by weight of the monomer. It is possible that the information obtained will lead to a better understanding of the nature of restorative resins.
