Two tests were performed on three different tooth paste samples by a compression to a specific distance and an adhesive test. Differences were seen in the firmness, tackiness, work-of-adhesion, and stringiness. Three types of toothpastes were evaluated for firmness, adhesiveness and stringiness. A compression test was used to differentiate the firmness while the an adhesive test was used for stringiness and adhesiveness.
