Explanation of Criteria
for Each Column
| Column A: | Cost per Milliliter The scale for ranking cost broke down as follows: |
|
|
| Column B: | Color Change All bleaches lightened teeth about 2 shades. Variations from this mainly depended on the patient. All bleaches received a ranking of 4 meaning all were excellent. |
| Column C: | Decrease in Active Ingredient
During Use It was determined what percentage of bleach remained after 0.5, 1, 2, and 4 hours. A graph of the degredation was made and the area under the curve was measured (% / time). The scale broke down as follows: |
|
|
| Column D: | Directions The four components assigned as necessary were: Dr's instructions, patient instructions, tray fabrication instructions, and photos/diagrams of steps involved in dispensing gel into tray and inserting tray into mouth. The following grading scale was used: |
|
|
| Column E: | Viscosity Each gel will be given a score based on the following scale: |
|
|
| Column F: | Taste Score based on the following scale: |
|
|
| Column G: | User Satisfaction Survey Subjects gave grades based on the following scale. |
|
|
| Column H: | Total Contact Time A list of total treatment hours was evaluated and broken down based on the following scale: |
|
|
| Column L: | Columns A - H were averaged to give an overall performance score for each bleach. |
|
E. Conclusions
|
| All 23 products studied lightened teeth about 2 shades. All use hydrogen peroxide as their active ingredient (carbamide peroxide is a mixture of hydrogen peroxide and urea). The differences among the products are subtle and involve personal preferences. Based on these points, clinicians could consider allowing patients the option to choose among several products offering different tastes, contact times, delivery systems, and costs. |
