Evaluation of Monomers and Photoinitiators for Dental Composites

Table 1 lists the materials used. PEM and BisGMA were evaluated as the primary monomers. TEGDMA, a monomer used in many commercial composite resins, was used as a diluent monomer for both. Figure 1(A)–(C) shows the monomer molecular structures. Two monomer/diluent proportions (70/30 and 50/50 by weight) were used for the comparison. These monomer mixtures are designated 70PT and 50 PT for solutions containing PEM-TEGDMA, and 70BT and 50BT for those containing BisGMA and TEGDMA, respectively. Camphoroquinone (CQ) with ethyl-4-dimethylaminobenzoate (EDMAB) as co-initiator, and diphenyl(2,4,6-trimethoxybenzoyl) phosphinoxide (DPO) were evaluated as visible light photo initiators for both monomer groups. 1(w)% Initiator was added in both cases.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
