The Experiment Contents Confirmation

  1. Title: The effect of LED electric toothbrush on gingivitis
  2. Material, Target and Method

Material: Test Group - Normally operating Pro-Medic Multiplex (VIS-IR-Ultrasonic)
Control Group - with LED not operating Pro-Medic Multiplex

 

      Target: 30 patients with gingival bleeding and gingivitis who have visited Dental Hospital of Dankook University, South Korea
Method: 30 patients divided by 15 in Test & 15 in Control Group to brush the gums for 4 weeks using the respective
toothbrushes above. By measuring the Gingival index (GI) and Plaque index (PI) before the experiment (baseline),
2nd week and 4th week after the experiment to calculate the gingivitis reduction effect

  1. The Result
  2. GI: Compared to the Control Group, the Test Group of the 2nd and 4th week showed a

statistically significant reduction in GI.

 

* Inflammation
   Standard → Normal

 

  1. PI: There are no significant differences between the two groups,

The Test Group shows a significant difference between baseline and 4th week,
   and the plaque has been continuously reduced. (plaque prevented).

 

* Statistical significance carried out by Mann-Whitney test and Wilcoxon signed test

 

  1. The Conclusion

LED electric toothbrush shows a statistically significant GI reduction effect,
And PI is anticipated to continuously decrease by its long-term use
Thus confirmed effective on gingivitis reduction.

The protocol was reviewed and approved by the Institutional Review Board(IRB) of
