Brief 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.

Condition or disease Intervention/treatment Phase
Tooth Discoloration Device: ToothWave Device: powered toothbrush Not Applicable

Detailed 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.

Primary Outcome Measures :
  1. Extrinsic Stains [ Time Frame: 6 weeks ]

    Extrinsic Stains will be evaluated using the validated Lobene Stain Index (LSI)

    Stain Intensity score range is between 0 and 3, where:

    0 = no stain

    1. = light stain
    2. = moderate stain
    3. = heavy stain

    The mean stain intensity will be calculated for both the gingival and body regions of the incisor teeth for each subject.

    Stain Area score rage is between 0 and 3, where:

    0 = no stain

    1. = stain covering up to one third of region
    2. = stain covering up to two thirds of region
    3. = stain covering more than two thirds of region

    The mean stain area will be calculated for both the gingival and body regions of the incisor teeth for each subject.



Secondary Outcome Measures :
  1. Tooth color assessment [ Time Frame: 6 weeks ]
    VITA Bleachedguide 3D-Master shade guide, includes 29 shade levels defined by the American Dental Association (ADA). These shade levels represents the brightness of the tooth where 1 is the whitest and 29 is the darkest shade.
