We know that palatal injections can be very uncomfortable for some patients. I would like to describe my technique for anesthetizing an upper first molar region when palatal numbness is needed. Using this technique, I have found that effective palatal anesthesia can be achieved with minimal discomfort.
First, inject one carpule of 2 percent lidocaine with 1:100,000 epinephrine, following the textbook technique for buccal infiltration in the molar region. Then click once with the intraligamentary syringe (such as N-Tralig, Miltex Instrument Co. Inc.) (containing 2 percent lidocaine with 1:100,000 epinephrine) into the distal buccal gingival papilla and once more into the mesiobuccal gingival papilla. Look for blanching of the lingual palatal tissue. Next, administer a normal palatal injection or inject into the blanched palatal area, which usually is gingival to the preferred injection site, and follow with a normal palatal injection.
This technique can be used for all maxillary teeth.
This technique can be used for all maxillary teeth, and any pressure syringe should be effective.
