Clinical Trial Summary

This study is a single blind, prospective study aimed to evaluate the safety and efficacy of the Silk'n ToothWave Power Toothbrush for stains reduction and improvement of teeth shade.

Description:

The study includes 84 treatment sessions, twice a day, and 4 clinic visits over a period of 6 weeks.

One treatment group (Silk'n power toothbrush - ToothWave) and 1 control group (an ADA approved power toothbrush (PTB)) will participate in the study.

For each patient, efficacy assessment data will be collected at baseline, 4 weeks, and at 6 weeks. The average stain data will be calculated for each group.

Treatment is defined as a timed, 2 minute brushing of the teeth according to the manufactur-er's instructions, twice daily (morning and evening). Brushing will be undertaken using the Silk'n toothbrush and standard fluoride toothpaste. The control group will use an ADA ac-cepted PTB and the same standard fluoride toothpaste.
