Dental erosion in a group of British 14-year-old school children Part II: Influence of dietary intake

Effect of pH on tooth discoloration from food colorant in vitro

“…8,9 In addition, other investigators have shown that highly pigmented, acidic beverages cause both tooth discoloration and dissolution of hard tooth structures. [13][14][15][16] Based on the current results, only the acidic, pigmented solution caused significant extrinsic as well as intrinsic tooth discoloration compared to highly pigmented neutral or alkaline solutions. Therefore, a low pH not only compromises the integrity of the enamel surface clinically, but may also increase the likelihood of tooth discoloration in the presence of highly pigmented foods/beverages.…”

“…Investigators have shown the hardness in enamel can diminish significantly ( 84%) after immersion in orange juice, carbonated beverages, sport drinks, beer and other acidic drinks. [13][14][15][16] The significant extrinsic discoloration in the treatment specimens may be explained by enamel dissolution inducing surface roughness from the acidic pH, allowing penetration of subsurface color into the body of the tooth. 2,5 Image analysis and color studies have been reported to be the most suitable method to measure tooth color.…”

“…It was hypothesized that acidic food colorant media (FCM) would cause both extrinsic and intrinsic tooth discoloration since reduced pH has been associated with increased enamel surface dissolution. [11][12][13][14][15][16] The following null hypotheses were tested:…”

Soft drinks and dental health: A review of the current literature

“…Assessment of erosion in 14 year-old children in the UK revealed that over 80% regularly consume soft drinks. 25 …”

A clinical study in situ to assess the effect of a food approved polymer on the erosion potential of drinks

“…The potential of acidic soft drinks to cause dental erosion has been established through a combination of epidemiological data 1,2 and studies in vitro and in situ. [3][4][5][6][7][8][9][10][11][12][13] The consumption of acidic soft drinks particularly by the young in many countries including the UK 14 is already high and has been increasing for years.…”
