Effect of Calcium Carbonate- Containing Tablet on Saliva Acidifi ed by Black Vinegar Consumption - An in vitro and in vivo Study

Objective: Tooth erosion is an increasingly common dental problem caused by acidic foods and beverages. Some people consume black vinegarfor its potential health benefi ts. Advising them to stop consuming black vinegar may not be appropriate because of these benefi ts. We developed astrategy to prevent salivary acidifi cation using a calcium carbonate-containing tablet originally developed for the treatment of halitosis.Methods: Young, healthy female volunteers (20-21 years old, n = 20) were recruited and administered a calcium carbonate-containing tablet afterconsuming black vinegar.Results: The tablet neutralized acidifi ed saliva more rapidly than the control gum. We also administered the tablet to a patient with severe tootherosion. No progression of tooth erosion was observed, even though the patient continued their habitual black vinegar consumption.Conclusion: These fi ndings suggest that the calcium carbonate-containing tablet has a salivary neutralizing effect and can regulate salivary pHwithout requiring changes in black vinegar consumption habits.
