Clinical Trial Summary

Study title: The Efficacy and Safety of tooth bleaching procedure using Y10 Whitening toothpaste and RF current

The Device: The Brighttonix Y10 Tooth Whitening system is indicated for use in painless non-invasive tooth whitening treatments.

Design: Single center, randomized, controlled, double blind, two-arm, prospective clinical study.

Follow up visits at 7 days (phone visit), 12 weeks and 26 weeks.


Description:

Purpose: To assess the efficacy and the safety of tooth bleaching procedure using Y10 Whitening toothpaste and RF current (Y10 Device), versus placebo (no RF current and off- the -shelf non bleaching toothpaste) in healthy patients seeking tooth bleaching.

No. of Subjects/Sites: A total of 60 patients at Hadassah Medical Center will be randomized, 30 patients for the test arm, and 30 patients for the placebo arm.

A 40% to 60% male (or female) ratio will be maintained.

Target teeth: At least 4 teeth between teeth 13-23 (Upper front teeth) according to the international teeth numbering system.

Upper and lower teeth will be treated with the same treatment arm as described.

Endpoints:

Primary endpoint:

• At the end of the treatment (V3), compared to prior of treatment, the mean shade change will be at least two shades (Vita Bleachguide 3D Master, Vita P/N: B361) as measured at the middle one-third area of the labial surface of the selected target teeth.

Secondary endpoints:

- Compared to prior of treatment, the mean shade change at 3 and 6 months will be at least one shade (Vita Bleachguide 3D Master, Vita P/N: B361) as measured at the middle one-third area of the labial surface of the selected target teeth.

- Compared to prior of treatment, color change evaluates with a spectrophotometer (VITA Easyshade Advance 4; VITA Zahnfabrik, Bad Sackingen, Germany), before and after treatment, at 3 and 6 months will be at least one shade. (Device with a high reliability, over 96%, Kim-Pusateri Et al. Reliability and accuracy of four dental shade-matching devices. Journal of Prosthetic Dentistry United States 2009;101(March (3)):193-9.)

- Compared to prior of treatment, the mean shade change for the lower teeth numbers 43-33 after treatment, 3 and 6 months will be at least one shade.

- Lesion in the gingiva of the upper and lower teeth (+/- in each of the teeth numbers 33-43, 13-23 after treatment and 3 months.

- Compared to prior of treatment - teeth sensitivity to cold and touch stimulation - target teeth - VAS scale after treatment, 3 and 6 months. For the VAS, the participants will place a line perpendicular to a 10-mm-long line with zero at one end indicating ''no TS'' and the other end indicating ''unbearable TS.''

- Patient oral questionnaire - post treatment, 7 days, 3 months, 6 months (See below).

- Patient Reported Outcomes: (Scale 0-4). OHIP14—aesthetics questions for patients that received dental bleaching - (see below) - before treatment and in 3 months.

- Periodontal parameters at baseline, 3 and 6 months: plaque index, sulcular bleeding index, pocket depth - all at the target teeth. (See below details).
