本研究的目的是评估再矿化所需的时间，以重建受侵蚀牙釉质对刷牙磨损的抵抗力。用84颗牛前牙制作釉质标本。样本被平均分配到7组(A-G)，并被提交给10个交替的去矿化和再矿化周期，其中包括刷牙磨损。通过将样品浸泡在腐蚀性软饮料Sprite Light(R)中1分钟来完成脱矿。标本在人工唾液中储存0min(A)、10min(B)、60min(C)或240min(D)进行再矿化。每次再矿化后，标本在自动刷牙机中刷牙。E组(侵蚀240min，不刷牙)、F组(侵蚀，但不再矿化，不刷牙)和G组(刷牙，但不腐蚀，不再矿化)作为对照。完成后，牙釉质的丢失通过轮廓测量法来确定。获得以下数值(平均值+/-SD)并进行统计分析(p
The objective of the study was to evaluate the period of remineralization needed to re-establish the resistance of eroded enamel against brushing abrasion. Enamel specimens were prepared from 84 polished bovine incisors. The samples were evenly distributed among 7 groups (A-G) and submitted to ten alternating de- and remineralization cycles which included abrasion by toothbrushing. Demineralization was accomplished by immersing the specimens in the erosive soft drink Sprite Light(R) for 1 min. Remineralization was performed by storing the samples in artificial saliva for either 0 min (A), 10 min (B), 60 min (C) or 240 min (D). After each remineralization, the specimens were brushed in an automatic brushing machine. Group E (erosion and 240 min remineralization, but no brushing) group F (erosion, but no remineralization and no brushing), and group G (brushing, but no erosion and no remineralization) served as controls. After performing the cycles, loss of enamel was determined by profilometry. The following values (mean +/- SD) were obtained and statistically analyzed (p
