For use in the anterior portion of the mouth, the HVE tip is placed on the ________.

  1. Same side where the dentist is working

  2. Opposite of where the dentist is working

  3. Directly in front of the dentist

  4. Anywhere, as long as it is steady

The correct answer is: Opposite of where the dentist is working

When using the HVE tip in the anterior portion of the mouth, it is important to place it on the opposite side of where the dentist is working. This allows for better suction and control of saliva and debris in the area being worked on. Placing the HVE tip on the same side as the dentist may lead to obstruction or accidental suction of dental instruments, while placing it directly in front of the dentist may not effectively remove saliva and debris from the working area. Option D is incorrect because the HVE tip should be placed in a specific location for optimal function, rather than anywhere on the patient's mouth.
