What is the primary reason for placing the High Volume Evacuator tips slightly distal to the tooth?

Placing the High Volume Evacuator (HVE) tips slightly distal to the tooth enhances the operator's line of sight during procedures. This positioning allows the dental assistant or operator to have a clearer view of the working field, which is crucial for effective diagnostics and treatment. A clear line of sight aids in precise operation, particularly when performing intricate procedures where visibility is key to avoiding damage to adjacent teeth, tissues, or dental materials. Maintaining an unobstructed view helps the dental professional ensure that everything is executed correctly and safely.

While patient comfort and suction efficiency are important considerations, they are secondary to the critical need for visibility in the dental setting, particularly during procedures involving restorative work, extractions, and other detailed treatments.
