Background & Aim: The abrasive quality of children’s toothpaste has long been the concern of dental professionals. On the other hand, manufacturers have tried to improve the quality and establish ingredient standards. This study was designed to compare the abrasiveness of three locally produced toothpastes, namely Darugar, Pooneh and Kam with Oral-B standard.
Materials and Methods: This experimental study was conducted using 24 samples of composite blocks imbedded in acrylic material. The weight of each specimen was measured by a digital scale at 0.0001gr accuracy. Each specimen was brushed with 200gr force along with the selected tooth paste solutions using V8 cross brushing machine. The weight of each specimen was measured after 5000, 10000, 15000 and 20000 strokes. The mean weight-loss as well as their standard deviations were calculated for each group. The collected data was then analyzed using ANOVA and Tukey statistical tests.
Results: No significant difference was detected between four types of toothpastes after 5000 and 10000 strokes. However, significant differences were observed between Darugar toothpaste and the rest (Kam, Pooneh and Oral-B) after 15000 and 20000 strokes.
Conclusion: Darugar pediatric toothpaste showed higher abrasive rate when compared with other toothpastes. The amount of wear was shown to be similar in Kam, Pooneh and Oral-B.
Key word: Abrasion - Pediatric toothpaste – Profilometer - V8 cross brushing machine.
