Primary outcomePrimary: Concentration of Bisphenol A in Saliva — 0.25 ng/ml — p=<0.05
Summary
It has been reported that therapy with polymer-based dental filling materials was associated with higher concentrations of bisphenol A in saliva and urine directly after the treatment. The objective of the present project is to gain knowledge about the concentration of bisphenol A in saliva and urine before and after treatment with polymer-based dental filling materials, using sensitive analytical methods.
