Brief Summary:
The objective of the study is to evaluate the safety and efficacy of the home-use device Silk'n toothbrush (ToothWave) for the improvement in dental health through the reduction of plaque, gingivitis, and calculus.

Condition or disease Intervention/treatment Phase
Gingivitis Plaque Calculus, Dental Device: RF-utilizing powered toothbrush Device: Control placebo with no RF Not Applicable

Detailed Description:

This is a single blind, prospective study aimed to evaluate the safety and efficacy of the Silk'n toothbrush in reduction of gingivitis, dental plaque and calculus.

The study includes a total of 168 treatment sessions, twice a day, and 5 clinic visits over a period of 12 weeks.

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

For each patient, assessment data will be collected at baseline, 4 weeks, and at 6 weeks. Calculus condition will be measured after 12 weeks in addition to the other timepoints. The average data sets will be calculated for each group.

Treatment is defined as a timed 2 minutes of teeth brushing in a regular manner, twice a day (morning and evening). Brushing will be undertaken using the Silk'n toothbrush and standard fluoride toothpaste. The control group will use a regular PTB and standard fluoride toothpaste.
