Assessment of the Abrasivity of Chinese Toothpastes
Abstract：AIM:To investigate the dentine abrasivity of four commonly used Chinese dentifrices.METHODS:The freshly extracted sound human teeth were embedded in blocks of epoxy resin,then which were ground flat on a grinding/polishing machine.A window of dentine was exposed and subjected to a total of 1000 cycles of toothbrushing using a purpose made rotary toothbrushing machine.The surface profiles of the tooth specimens were assessed before and after toothbrushing with a Talysurf 2 Surface profilometer.RESULTS: The Chinese products generally showed greater abrasivity than many of the European products.CONCLUSION:Consideration should be given to the potential tooth wear that tested products may cause if used over longer periods as part of the preventive strategy to improve oral hygiene of patients.
