Here’s A Novel Direct Injection Buffering Technique for Local Anesthetics
We are pleased to welcome once again Dr. Mark Donaldson to CDA Oasis. In a previous study that Drs. Mark Donaldson and Jason Goodchild conducted, two options available for buffering local anesthetics in dentistry were compared. One using the Onpharma® mixing system (Onpharma), and the other by hand mixing with 8.4% sodium bicarbonate using a "remove and replace" technique. The results of that study showed no statistically significant difference in buffering outcomes between the two methods.
The present follow-up in vitro study introduces and examines a less complex, direct injection, chairside hand-mixing approach, using four commercially available dental local anesthetic preparations.
- The potential benefits of buffering local anesthetic solutions prior to injection, such as decreased injection pain, faster onset, and greater depth of anesthesia, may be particularly advantageous in patients who have difficulty achieving profound anesthesia for clinical dentistry, and for anesthetizing infected areas.
- Dentists can effectively buffer local anesthetic preparations, using commercially available mixing systems or by utilizing a hand-mixing technique.
- Rather than using a remove and replace technique, practitioners may consider a direct injection technique, adding 0.1 mL of 8.4% sodium bicarbonate directly into any local anesthetic cartridge regardless of local anesthetic concentration.
We hope you you find the presentation informative. We always look forward to hearing your thoughts and receiving your questions and/or suggestions about this post and other topics. Leave a comment in the box below or send us your feedback by email.
