N2 - Objectives: The role of fluoride in preventing erosion and abrasion on dentine remains unclear. The aim of this study was to investigate the effect of repeated applications of a 0.05% fluoride mouthwash and an adhesive on wear of dentine using stainless steel discs reference points and a laser profilometer. Methods: Small stainless steel discs were bonded to 60 caries free extracted molars which had previously been sectioned horizontally. The teeth were equally divided and subjected to four modalities in an erosion and abrasion laboratory model. Step heights were measured from the metal discs using a non-contacting laser profilometer at 100, 500, 1000, 2500 and 5000 cycles. Results: The results after 5000 cycles showed that dentine coated with a dentine adhesive (0.015 mu m, S.D. 0.090) had statistically less wear than fluoride (0.127 mu m, S.D. 0.150), abrasion and erosion (0.182 mu m, S.D. 0.150) or abrasion only (0.096 mu m, S.D. 0.090) (p <0.001). Conclusion: In conclusion dentine surfaces coated with a resin-based adhesive provided more protection against erosion and abrasion than a fluoride mouthrinse. There were no statistical differences between the modalities for cycles less than 5000. (C) 2007 Elsevier Ltd. All rights reserved
