A dental patient of ours has positional dizziness (for years). He is unmedicated. Is it safe to give him nitrous oxide?
Checkup. Ofcourse, your patient has been thoroughly checked by his physician for a thorough checkup. The gambit could run to uncontrolled blood pressure to a brain tumor. I would try at all possibilities not to use nitrous. If he is not extremely fearfully, just use local anesthesia and gentleness. Take the patients mind off of where he is and talk about his or your favorite subject.
