Aspiration or just plain suckers.
Aspiration is one of the most essential services in the dental surgery, for patient comfort, clear vision and assistance with asepsis control, and is imperative during GA/RA procedures for the safety of the patient and for the removal of anaesthetic gases from the working environment. It should be noted that not all vacuum motors are suitable for this application as some brush by-pass motors could present sparking problems if used with these gases.
