Does one dare to drink a smoothie, if one has one or more teeth? A recent investigation bears on that question:
“The effects of smoothies on enamel erosion: an in situ study,” Hanein Ali, D. Clin. Dent thesis, 2012, University of Leeds. The author reports:
“Conclusion: Smoothies are acidic and have high TA levels. Innocent® strawberries and bananas smoothie had an erosive potential to the teeth. However, its erosive effect was significantly less compared to citric acid after 21-days pH cycling protocol using an in situ model.”
The study has just made a new appearance, transformed from a thesis into a dental journal paper, having acquired a co-author and (presumably — we have not seen the new version in full) revisions:
“The effects of smoothies on enamel erosion: an in situ study,” Hanein Ali [pictured here] and Jinous F. Tahmassebi, International Journal of Paediatric Dentistry, epub August 4, 2013.
(Thanks to investigator Adrian Smith for bringing this to our attention.)
