Erosive Potential of Bottled Salad Dressings

Julia J. Hartz/ Alessio Procopio / Thomas Attin / Florian J. Wegehaupt

Purpose: A previous clinical study showed that the prevalence of erosive toothwear in vegetarians is statistically significantly higher than in nonvegetarians, due to the consumption of vinegar and other acidic foodstuffs. To adequately inform patients, this study investigated the erosive potential of bottled salad dressings available in Switzerland and compared it with that of orange juice. Materials and Methods: One hundred enamel samples of bovine teeth were divided into ten groups. Samples were placed in 1 of 9 bottled salad dressings or orange juice (Granini) for 2 min. Afterwards, they were rinsed with Zrich tap water for 30 s, followed by abrasion with a toothbrush for 20 brush strokes and a toothpaste-saliva mixture. Erosive/abrasive enamel wear was determined with contact profilometry after 40 cycles. Results: The enamel wear (median/IQR) caused by Tradition Sauce Balsamique (9.5 m/5.3 m), M-Classic Dressing Italiano (10.9 m/12.3 m), Betty Bossi Balsamico Dressing (9.4 m/4.5 m) and Thomy Balsamico Vinaigrette Dressing (14.2 m/6.5 m) was statistically significantly higher than that caused by orange juice (2.4 m/0.8 m). Enamel wear caused by M-Classic Dressing French Joghurt (0.2 m/0.2 m) and Coop Qualit & Prix French Dressing (1.2 m/1.0 m) was statistically significantly lower compared to that of orange juice. Conclusions: The pure balsamico vinegar-based dressings (Italian type) showed a statistically significantly higher erosive potential than orange juice, whereas dressings containing calcium-rich products (enriched with milk and/or cream) (French-type) caused lower enamel wear than orange juice. The study shows that some bottled dressings have erosive potential even higher than orange juice and patients should be informed accordingly.
