Question 10 of 35
That answer is correct.
An anesthetic cartridge can contain the following:
local anesthetic drug
For example, lidocaine
Also called a vasopressor, these will lower the pH of the solution and are only found in cartridges that indicate that a vasoconstrictor is present
This serves as an antioxidant for the vasoconstrictor to prevent it from being biodegraded by oxygen. Sodium bisulfite is used for this purpose.
This provides volume to the solution.
Sodium chloride helps to make the solution isotonic (similar) with the body's tissues
Methylparaben has NOT been added to dental cartridges since 1984 due to reports of increased allergic reactions.
