Objectives:
To investigate the in vitro dentine wear after tooth brushing with a range of nine toothpastes.
Methods:
70 bovine dentine blocks (aproximately 1 cm long) were used. Specimens were brushed in vitro with toothpastes with a range of abrasive. All the specimens were submitted to 10,000 brushing cycles with a 200g load. Initial and final weight and profile data were obtained using an analytical scale and a profile projector respectively.
Results:
Significant differences between the test products were found (p < 0.05). The mean dentine wear ranged from 0.039 to 0.006g and 0.502 to 0.185mm, with the highest wear for the whitening toothpastes.
Conclusions:
This study demonstrated that the type of toothpaste abrasive can contribute to dentine wear.
