Hello! I’m a 3rd year dental student and I have an assignment on “future trends in pain control”. I’m relying mainly on Stanley F. Malamed’s Handbook of Local Anesthesia (7th edition, 2020) as my main source, and in a chapter dedicated to this topic they mentioned longer and ultra long acting local anesthetics derived from shellfish and puffer fish toxins, liposomal bupivacaine, and light-activated and light-inactivated local anesthesia. Has any of you heard, read or saw another new technology in this topic, and does anyone know another source that I can check out for more ideas?
