Understanding interactions between graphene and local anesthetic molecules applied in dentistry – Towards the prolonged effects of local anesthesia - ScienceDirect
September 10, 2022 - However, to understand the role of those modifications in the interactions with selected anesthetic molecules at the molecular level, it is necessary first to understand the interaction with the pristine graphene. We hope that the results of this study serve as a sound foundation for further studies in which modified graphene nanostructures will be considered as possible adsorbents of the anesthetic molecules applied in dentistry.

r/Dentists on Reddit: Problem of Graphene Oxide Being Found in Dental Anesthesia
May 12, 2024 -
Dr Ricardo Delgado and a team of scientists around the world using microscopes is finding what is called "graphene oxide" in anesthesia being used in dentistry. Now, generally dentists in Spain are using the "Delgado Method" using heat and magnets to pull the graphene out of the indivual vials, and The American Bio Dental Center in Mexico is sending the various anesthetics out to the University of Mexico labs for testing of the graphene oxide. Why is that here in America, the dentists are not aware of or want to help in testing for this, instead pushing patients away who bring up the subject?

The reason is that it is a bogus claim. They have started testing long-lasting anesthetic that graphene oxide would help prolong the effect of in cases of surgery, but this is not the case with the shorter acting lidocaine and articaine used in dental offices. If there was graphene oxide that stuff would last for days. Also, using a lighter and magnet would in no way cause graphene oxide to precipitate. They say it’s safe to inject over half once you use a lighter and magnet. There’s no way anyone would inject something contaminated that way. That “scientist” would never inject anesthetic with a visible precipitate, or he’d be sued and lose. This is the new urban myth like needles in candy. Don’t be scared by what Tik Tok “experts” throw around.

If this was true the doctors involved would say that dental anesthetic is not safe to inject into anyone. They wouldn’t say, heat it up with a lighter, and pass a magnet over it, and now it’s safe. If they were legitimate it would say, heat anesthetic to the precipitation temperature of “x” for a time of “y” minutes, then remove anesthetic and deposit in an uncontaminated carpule leaving the foreign substance behind. There’s no way it’s safe to inject a portion of a carpule if it was contaminated. That shows that they are not a reliable source.

One spectrum also displays a broad, low-intensity feature in the ~2700 cm-1 range that may represent a weak 2D band, however, the remaining spectra lack a discernible 2D feature. Although some studies have identified materials as graphene oxide in the absence of resolved 2D band, its structural heterogeneity inhibits confident classification by Raman spectroscopy alone.
