Bisphenol A Released From Composite Fillings does not alter serum hormone levels, Study finds
Composite resins are the most preferred filling material because of their excellent aesthetic qualities. However, a filling material should also be biocompatible as well as aesthetic.
The most widely used monomers in resin matrix are urethane dimethacrylate (UDMA), bisphenol A glycidyl methacrylate (BISGMA), and triethylene glycol dimethacrylate (TEGDMA).
According to the literature, only a few epidemiological studies have investigated the relationship between BPA exposure and health-related end points, and as a result, human studies on the possible health effects of BPA exposure are limited.
BPA in both serum and saliva released from composite resins was found, suggests a recent study conducted at the Department of Restorative Dentistry, Faculty of Dentistry, Atatürk University, Erzurum, Turkey. However, it was determined that the released BPA levels were below the toxic doses and did not alter hormonal balance.
The study is published in the International Dental Journal.
Pinar Gul and colleagues aimed to determine the serum and saliva bisphenol-A (BPA) levels and to examine the effects of serum BPA on reproductive hormone levels after healthy men were treated with composite fillings.
