When should the high volume evacuator be placed in relation to the hand piece and mouth mirror?

The high volume evacuator (HVE) should be positioned before utilizing the handpiece and mouth mirror for several essential reasons. First, placing the HVE in advance ensures that any debris, water, or excess moisture created during the procedure can be effectively managed right from the start. This preemptive setup helps maintain a clear operating field, which is critical for the dental practitioner to have good visibility and access to the treatment area.

Having the HVE ready beforehand also allows for efficient suctioning while working, minimizing the risk of the accumulation of fluids that could otherwise obstruct the view or create discomfort for the patient. This proactive approach promotes a smoother workflow and enhances the safety and effectiveness of the dental procedure.

In contrast, positioning the HVE during or after using the handpiece and mouth mirror might lead to delays or difficulties in maintaining a clean working environment, potentially compromising the overall quality of patient care.
