The best choice is both options A and B, as they work together to ensure that the anesthetic solution is not injected into a blood vessel. Using an aspirating syringe allows the dentist to check for blood or other fluids before injecting the solution, while always aspirating before depositing any solution ensures that the dentist does not inadvertently inject into a blood vessel. Using a periodontal ligament syringe is not necessary for this purpose.
