Purpose

To demonstrate the whitening effect of a toothpaste on natural dentition.

Procedure

47 patients with natural teeth brushed their teeth first with a dry brush and then twice with a test dentifrice. The productstested were Topol (15 patients), Crest (16 patients) and Supersmile (16 patients).

Patients were evaluated independently by three dentists to determine the changes that resulted from three brushings with the following grading scale:

0 - no discernible change

1 - slight change

2 - moderate change

3 - drastic change

The score for each patient was the sum of the grades given by three evaluators.

Results

Supersmile demonstrated a superior whitening or brightening effect on the sample population.

A one-way analysis of variance indicated a statistical difference between the groups at the.01 level.

Duncan, Scheffe and LSD tests all indicated that Supersmile was different from the other dentifrices at the .01 level.

Summary of evaluators scores

Results:

​Supersmile is 75% less abrasive than the limit set by the American Dental Association.
