Local anesthetics are chemical substances given infiltrative or at the surface, which temporarily block the implementation of pulses through nerve fibers. Thus they cause anesthesia of the tissue that is innervated by that nerve without damaging of the nerve. The aim of this study was to evaluate the role and benefits of local anesthetic buffering. Patients often complain of a burning sensation and burning in the area of anesthetic deposition due to the acidity of the anesthetic solution. With local anaestetic buffering these negative effects are removed. Latest advances in technology allow mixing of solutions for local anesthesia with alkaline substances immediately before injection of anesthetic, making the anesthetic’s onset quicker, more reliable, and more comfortable for the patient. The buffering process uses a sodium bicarbonate solution that is mixed with the cartridge of local anesthetic. The interaction between the NaHCO3 and HCL in the local anesthetic creates H2O and CO2. For buffering, Onpharma’s Onset Mixing Pen is most commonly used. The pen has cartridges of Onpharma bicarbonate solution and can be used to accurately buffer dental anesthesia. The process of buffering takes 5 seconds chairside and should be done immediately before the placement of a dental syringe and injection of the anesthesia. As a conclusion we can noted that buffering of the local anesthesia can have a lot of advantages in everyday dental practice for reducing the pain and discomfort caused by the injection process. Keywords: local anesthetics, anesthetic buffering, sodium bicarbonate solution.
