My periodontal hygienist wears high powered lenses that she removes when finished. others tell me their hygienists do not use them. benefits?

Better vision: Magnification loupes allow your hygienist to see better--it's the difference between her looking at teeth at normal size vs baseball size. That means she can see more detail, which should allow her to provide a more detailed cleaning. Cleaning teeth is not just visual, though--a lot is done by feel, especially between the teeth. So the loupes can provide a benefit, just not on all areas of teeth.

Good Job: If the hygienist feels she can do a better job with the lenses, good. If others do not, also good.

Detailed : Loopes are what you are referring to. Anyone involved doing dental procedures benefits when magnification is used. Detail are seen! and you can't treat what you don't see!

Loopes: High powered lease that act as a magnifying glass. May improve the detail available to the practitioner. Some practitioners prefer them, some do not. Individual decision. A personal decision.
