2. Place the HVE tip first, then the operator places the handpiece

3. Both placed simultaneously

4. Operator places HVE before assistant positions handpiece

The correct answer is: Place the HVE tip first, then the operator places the handpiece

The correct technique for placing the HVE (High-Volume Evacuator) oral evacuator is to place the HVE tip first, followed by the operator positioning the handpiece. This method ensures that the suction is established at the site of the procedure before any debris or fluids can become a problem. By positioning the evacuator tip first, the assistant can effectively manage any excess fluids or debris that may be generated during the procedure, thus keeping the working area clear and allowing the operator to maintain a clear line of sight. Additionally, placing the HVE tip first helps to prevent any obstruction or distraction to the operator who is handling the handpiece. This sequential placement fosters a more efficient workflow in the dental procedure, as it allows for coordinated teamwork between the assistant and the operator. Establishing the evacuator's position before the operator begins work is essential for maintaining a clean and dry field, which is crucial for many dental treatments.
