OraPharma Onset

More Comfortable Injections at the Dental Office! 

Dr. Lais is always thinking of ways we can improve our patient care.  Many patients dread getting numb.  Now there is a new way to make e injection more comfortable and it is called Onset from Orapharma.

The acidity of the local anesthetic solution itself as it is deposited into the tissues that is now controlled by buffering the solution immediately prior to use

Local anesthetics are powders that are insoluble in water.  Because the anesthetics are weak bases, they must be packaged as an acid that is approximately the pH of lemon juice. When we give an injection of local anesthetic, then bathe the tissue (pH equal to lemon juice). Hence the “bee sting” effect for the patient.

Using the sodium bicarbonate buffered solution gives anesthetic more of a neutral pH, which makes it less irritating to the tissue without the burning while giving faster results.  Typically it takes 10 to 15 minutes for the “numb lip” sign of anesthesia.  Using the buffered solution, we normally have profound numbing signs within 2 to 5 minutes!

Onset has been a substantial investment for the practice, but Dr. Lais feels it is worth the investment, to make our patients more comfortable during their dental visits. This process has made a large difference for patients who have always feared the pain from the injection.
