Where should the HVE be positioned on the operative tooth?

The correct answer is to position the High Volume Evacuator (HVE) closest to the dentist. This placement is important for maximizing efficiency during dental procedures. By positioning the HVE nearest to the dentist, the dentist can more easily control the working area and facilitate better visibility and access to the tooth being treated. This proximity allows for effective removal of debris, saliva, and any other fluids that could obstruct the view or the procedure itself, ensuring a cleaner and more manageable operatory environment.

Additionally, having the HVE close to the dentist helps diminish the risk of contamination and makes it easier to maintain a dry field, which is crucial for the success of many dental treatments. This approach also contributes to patient comfort, as it minimizes the potential for aspiration or swallowing of materials during the procedure.

The placement choices further from the dentist or at specific midpoints do not provide the same level of control and efficiency in managing moisture and debris in the operative field, which is critical for optimal outcomes in dental procedures.
