I can’t answer that.
But I can tell you that the nasal spray of “midazolam” along with nitrous oxide gas- inhalation sedation (IHS) - was studied on 100 children between the ages of 3 and 13, who were originally referred for “general anesthesia” and 96% of the required dental treatment was completed successfully. There was no need for general anesthesia and parents were present with the children during the procedure.
The National Institute of Health recommends this technique instead of Dental General Anesthesia. (DGA)
You can read the study for yourself here:

Of course skilled dentists and staff as well as life saving equipment and medication is a must!
I can tell you general anesthesia is close to death, and I’ve lost count of the number of children who have died in the last two years. (8) and rising.
I can tell you seven studies of Inhalation sedation, using nothing but nitrous oxide (along with local numbing), without the nasal spray have taken place. These studies also used children who had been referred for general anesthesia.
The studies were reported to have a “remarkable degree of consistency in the reported treatment effectiveness despite other differences in patients”.
What were the results?
