Understanding interactions between graphene and local anesthetic molecules applied in dentistry – Towards the prolonged effects of local anesthesia - ScienceDirect
September 10, 2022 - It was synthesized in 1905 by Alfred Einhorn, and introduced in clinical practice by Heinrich Braun [7]. From the aspect of chemical structure, it belongs to the amino ester group of compounds. Among other things, this anesthetic was the first local anesthetic that obtained general acceptance in the United States. It remained a popular choice of dentists until 1948 when lidocaine (LID) suppressed it.

r/Dentists on Reddit: Problem of Graphene Oxide Being Found in Dental Anesthesia
March 20, 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.

Lidocaine-loaded reduced graphene oxide hydrogel for prolongation of effects of local anesthesia: In vitro and in vivo analyses - PubMed
The ex vivo release study demonstrated the ability of the Pluronic® F68-reduced graphene oxide hydrogel to prolong release up to 10 h, owing to the strong π-π interactions between the graphene oxide and the lidocaine. In comparison with a commercial lidocaine ointment, the developed graphene oxide hydrogel showed sustained anesthetic effect in the radiant heat tail flick test and sciatic nerve block model.
