... of 64 groups, enamel specimens were demineralised (10 days, 6 × 2 min/day) using different acids (1, 0.5 and 0.3% citric acid at native pH 2.3, 2.5 and 2.8, respectively, and 0.3% citric acid adjusted to pH 3.6) with two different movement types (jerky or smooth). Specimens were immersed (2 × 2 min/day...

...E. Bashir; A. Gustavsson; F. Lagerlöf Erosion of the buccal incisor enamel, most frequent in the upper jaw, has been associated with excessive oral exposure to citric acid-containing foodstuffs. The aim of the study was to determine the retention of citric acid at different sites in the mouth after...

...E. Bashir; F. Lagerlöf Citric acid contained in beverages and foods is one of the main causes of enamel erosion. It was hypothesized that the clearance of citric acid from saliva would influence the degree of salivary saturation with respect to hydroxyapatite (OHAp). Ten subjects rinsed with 2...

...-flavoured sugar-free chewing gum containing citric acid on enamel remineralization, and acid resistance of the remineralized enamel, using an in situ remineralization model. The study utilized a double-blind, randomized, crossover design with three treatments: (i) sugar-free gum (2 pellets) containing 20 mg...

... whether enamel and dentine specimens licked by the tongue after exposure to acid lost more tissue than when exposed to acid alone. Flat enamel and dentine specimens were prepared from human third molars and taped to expose a window of tissue. Three groups of specimens were exposed to citric acid for 10...

...M. Eisenburger; M. Addy; J.A. Hughes; R.P. Shellis The aim of this in vitro study was to determine the influence of remineralisation time on rehardening of surface–softened enamel after citric acid erosion. Seven groups of 13 samples of human enamel were eroded in 0.3% citric acid at pH 3.2 for 2 h...

... environment at the buccal aspect of the upper first molars and at the lingual aspect of the lower incisors in 3 subjects over periods of 24 h. Enamel specimens with and without 24–hour pellicles were immersed in citric acid (0.1 and 1%) for periods ranging from 30 s to 5 min, and processed for measurement...

... The aim of this study was to use ultrasonication and profilometry as methods to study de– and remineralisation of citric acid–eroded enamel at different pH values. Seventy–eight polished human enamel samples were divided into three test and three control groups of 13 specimens each. Three...

...M. Hannig; M. Balz This study assessed the protective effect of the salivary pellicle formed in vivo during 24 h or 7 days against demineralization of bovine enamel caused by citric acid. In addition, the influence of acid treatment on the behavior of the pellicle was investigated. Enamel specimens...
