Isn't it like helping droplets coming from the mouth of the parient to flow towards the dentist's face/mouth? (of course protected by a respiratory mask, still ...)
- somid3 6y agoNo, the head of the dentist is usually always 45-degrees from the patient. Dentists NEVER look into the mouth of a patient head on. The vacuum is head on in front of the patient, the dentist is 45-degrees off. Imagine a equi-distant triangle of patient, dentist, and vacuum.
- jaclaz 6y agoI see, thanks.
