| - | Meet Mary Susan Lefever. | 0:01 |
| One of her parents took part in a toothpaste test | 0:03 | |
| that showed Crest reduces cavities. | 0:05 | |
| Can you tell who it was? | 0:07 | |
| Let's ask Mary Susan. | 0:09 | |
| - | My daddy. | 0:10 |
| - | (laughs) good girl. When was the test, Mr. Lefevre? | 0:11 |
| - | When I was a student at Indiana University. | 0:14 |
| - | How'd your group make out? | 0:16 |
| - | Not as well as the other group. | 0:17 |
| - | Because? | 0:19 |
| - | We used regular toothpaste. | 0:19 |
| - | While the others used Crest. | 0:21 |
| Now here's the story filmed at the university. | 0:23 | |
| On this side, they used regular toothpaste | 0:27 | |
| and over here they use Crest. | 0:30 | |
| Mr. McLean, did anyone know which toothpaste was which? | 0:33 | |
| - | No, we did not. | 0:36 |
| - | How many took part in the test? | 0:37 |
| - | About 250. | 0:39 |
| - | How old were you then? | 0:40 |
| - | We were sophomores and juniors. About 19 or 20. | 0:42 |
| - | Thank you. Mr. Lefevre, did you brush any special way? | 0:45 |
| - | No. They told us to brush as usual. | 0:48 |
| - | Who told you to do that? | 0:50 |
| - | The university scientists running the test. | 0:51 |
| - | Thank you. | 0:53 |
| The results: after two years, | 0:55 | |
| the Crest group had 34% fewer cavities, 34%. | 0:57 | |
| Such results show why Crest is the only toothpaste | 1:01 | |
| recognized effective against cavities | 1:04 | |
| by the American Dental Association. | 1:06 | |
| Their Council on Dental Therapeutics reports, | 1:08 | |
| "Crest has been shown to be | 1:11 | |
| an effective decay-preventative dentifrice | 1:12 | |
| that can be of significant value | 1:14 | |
| when used in a conscientiously applied program | 1:16 | |
| of oral hygiene and regular professional care." | 1:19 | |
| Protect your family with good dental habits, | 1:22 | |
| checkups twice a year, and Crest, | 1:24 | |
| the only toothpaste recognized effective against cavities | 1:27 | |
| by the American Dental Association. | 1:30 |
