During the loading of an anesthetic syringe, what should be loaded first?

Needle
Anesthetic cartridge
Plunger
Barrel

The correct answer is: Anesthetic cartridge

When loading an anesthetic syringe, the anesthetic cartridge should be loaded first. This procedure is crucial because it simplifies the assembly and ensures the safe handling of the syringe. By inserting the cartridge first, the practitioner minimizes the risk of contamination and ensures that the cartridge is properly aligned and seated within the syringe before securing any other components. Once the cartridge is in place, the plunger can be loaded to complete the assembly, allowing for proper aspiration and injection protocols later on. Loading the other components out of order could lead to complications, such as difficulty securing the cartridge or accidental contamination of the needle or plunger. Therefore, following the recommended protocol of inserting the anesthetic cartridge first is essential for maintaining both safety and efficacy in dental procedures.
