New toothpaste removes four times more plaque than other toothpastes

CHICAGO, USA: Microbial biofilms, or dental plaque, on teeth significantly contribute to the development of dental caries, gingivitis and periodontitis, and should therefore be managed through daily brushing and flossing. A recently published study has now shown that a new toothpaste, which contains teal disclosing agents to color and identify plaque build-up on teeth, helps users remove up to four times more plaque than a standard toothpaste does.

In the study, 35 healthy patients aged 18–64 who had all 12 anterior teeth were divided into two groups. At two visits to the University of Illinois at Chicago College of Dentistry over the course of seven to ten days, participants in the first group brushed their teeth with a control toothpaste only. Participants in the experimental group used the control toothpaste at one visit and the Plaque HD toothpaste, which contains an FDA-registered annatto seed extract dye, as well as FD&C Blue No. 1, giving the toothpaste a green color that adheres to intra-oral plaque, at the second visit.

After brushing, participants rinsed with fluorescein solution. The presence of plaque on tooth surfaces was visualized by plaque-bound fluorescein, photographed and digitally quantified to calculate the percentage of remaining plaque. The data analysis showed a statistically significant mean plaque reduction between the initial baseline appointment and the second appointment for the experimental group. While participants in the control group were only able to eliminate about 8 percent more plaque, participants in the experimental group removed over 50 percent more dental plaque compared with the first visit.

“This study demonstrates that brushing with a toothpaste with plaque-indicating dye, combined with proper use instructions, significantly increases plaque removal efficacy,” the researchers concluded.

According to the manufacturer of Plaque HD, the toothpaste incorporates Targetol Technology, which contains all-natural, plant-based disclosing agents, and colors any plaque. Currently Plaque HD is sold through dental and orthodontic offices across the U.S. and on Amazon. It is available in a professional version for $21.00 and a retail version for $14.95.

The study, titled “Evaluation of plaque removal efficacy of a novel dye-containing toothpaste: A clinical trial,” was published on Jan. 13 in the International Journal of Dentistry and Oral Science.
