Release of Monomers from Dental Composite Materials into Saliva and the Possibility of Reducing the Toxic Risk for the Patient

Background and Objectives: The objective of this study was (1) to measure the amount monomers released into saliva depending on time elapsed after hardening composite type monomer used; (2) with prolongation light-curing procedure, publish information whether it would be possible influence level leached monomers. Materials Methods: HPLC technique used monitor levels unpolymerized Bis-GMA, Bis/EMA, TEGDMA, UDMA from four commonly materials, a volunteer intact dentition. were monitored in 3 periods during 24 h hardening. From every material, 4 samples formed cured an LED lamp for 10 s, 20 40 60 s. After light curing, same polishing procedure blank samples. Results: We observed that material eluted its application. depended curing used. A s can reduce comparison standard especially higher molecular weight. Conclusions: Our confirmed hypothesis release gradually decreases increasing filling.
