Resources on Dental fillings

Much of the leaching and toxicity of the plastic filling actually has to do with how the dentist mixes the monomer & ingredients in office - and also how they apply it.

So if your dentist is aware of the risks, and many are, then they may take precautions that can really reduce the amount that you end up ingesting in your body.

Here are some studies you can share with youe dentist - on how to reduce your exposure to BPA and monomers in the application of composite resin fillings: 

• Once Resin Composites and Dental Sealants Release Bisphenol-A, How Might This Affect Our Clinical Management?—A Systematic Review
• Conclusions: Some clinical precautions should be taken to decrease the release of BPA, namely the use of rubber dam, the immediate polishing of all resins used, or the use of glycerin gel to avoid non-polymerization of the last resin layer, and mouthwash after treatment. Another preventive measure in addition to the above-mentioned is the use of the smallest possible number of restorations or sealants, a maximum of four per appointment. These measures are even more important in children, adolescents and pregnant women.

• A Look Into the Cytotoxicity of Composite Fillings: Friend or Foe?
• Greater cytotoxicity is produced by shorter curing times at higher light intensities emitted by the curing light source than by longer curing times at lower intensities [51].
• The addition of ceramic fillers has been shown to reduce the amount of monomer release and, as a result, can be considered for use in the composite composition for application in the oral cavity.
• Due to the lack of cytotoxicity of Admira Fusion (VOCO GmbH, Cuxhaven, Germany) on hGF and hPDLF cells, ormocer composites can be considered as a biocompatible alternative in clinical situations where a restoration in close association with the gingiva and periodontal ligament is required. It is possible to draw the conclusion that the supra-nano-hybrid resin-based composite material Estelite Quick Sigma (EQS) (Tokuyama Dental Corporation, Tokyo, Japan), which contains Bis-GMA and TEGDMA, is not cytotoxic to hGF and hPDLF cells. This is most likely a result of decreased monomer releases due to the improved polymerization technology.
•  Removal of the oxygen-inhibition layer results in the least quantity of cytotoxicity. To improve the biocompatibility of dental composites, clinicians should immediately remove the unreacted monomer particles from the resin surface after restoring the tooth with light-curing resin [49].

• Effect of various light curing times on the elution of composite components
• Conclusion Increasing the curing time compared to recommendation of the manufacturer reduces the release of most composite components. This could result in less exposure to human due to these substances.

Share them with your dentist so that they can help you avoid leaching of monomers & Bisphenols as much as possible
