Abstract

To evaluate, in vitro, the abrasiveness of 42 dentifrices and one dental pumice. Acrylic resin specimens were used for uniformity. The study used three different batches of 42 dentifrices and one dental pumice, with three specimens per product. Tests were performed on an automatic toothbrushing machine, producing 100,000 strokes of oscillating movements for each specimen with soft bristle toothbrushes, corresponding to 4.2 years of toothbrushing. The specimens were ultrasonicated in deionized water and dried. Wear was analyzed by the difference in the weight of specimens before and after toothbrushing and was correlated with type of dentifrice, purpose and abrasive agent by one-way analysis of variance. The dentifrices presented variation in percent weight loss, yet without significant difference according to the main abrasive agent (carbonate/silica), type of dentifrice (paste/gel), and purpose. Greatest weight loss was observed for dental pumice, followed by desensitizing, bicarbonate-containing, whitening, conventional and infant dentifrices and deionized water, though without statistically significant differences. Dentifrices with calcium carbonate and in paste form were more abrasive. The dental pumice was the most abrasive, followed by desensitizing, bicarbonate-containing, whitening, conventional and infant dentifrices.
