The application study with the ultrasonic toothbrush Emmi-dental Professional was carried out with 20 subjects. The age
The subjects were between 7 and 43 years old. I have the subjects' personal data.
For data protection reasons, the test subjects are listed under identification numbers in this report.

- Orthodontic treatments (fixed or removable braces – 11 subjects)
- gingivitis (4 subjects)
- Bleeding gums (3 subjects)
- Bad breath (1 subject)
Material and Method
The subjects were randomly selected for the study (random procedure). Four examination appointments
were arranged at intervals of ± 4 weeks. 1. appointment (initial examination)
The use of the EMAG ultrasonic toothbrush was explained to the subjects and their parents and the associated

concluding remarks
a) Summary of the results of the application study
(Please insert a general summary statement here – including with reference to the effectiveness of the
Ultrasonic tooth cleaning for plaque, smooth tooth surfaces, brighter (whiter) teeth and the identified
Effects in cases of gingivitis, bleeding gums and bad breath)
b) Some comments from me:
From my perspective as a pediatric dentist, I have experienced and seen progress in the use of the ultrasonic toothbrush.
This study was a lot of fun, just to see how critical children and young people can be. They discuss things a lot and I even had to prove to two of the test subjects using photos that their teeth were not free of plaque even after brushing because they had not used the technique correctly.
Two mothers who have suffered from bleeding gums for years have adopted this tooth brushing technique and happily told me after the third appointment that they were finally free of it.
A thought on my part: How effective is this brush after surgery in the jaw area or in people with periodontal disease?
