Abstract:
OBJECTIVES: The aim of present study was to evaluate the effect of hangover-curing beverages on dental erosion. METHODS: The pH and titratable acidity of 12 hangover-curing beverages were measured. Of these, we selected Morning Care, Condition Power, and Dawn 808 as experimental beverages and distilled water as control. The concentrations of fluoride, Ca, and P were measured for all four beverages. Bovine tooth enamel samples were treated with the four beverages for 1, 3, 5, 10, 15, and 30 min. Surface microhardness (Vickers hardness number [VHN]) was measured using the microhardness tester before and after treatment. The surface of specimens was observed under a scanning electron microscope (SEM) only after treatment. RESULTS: 1) The average pH of the hangover-curing beverages was 3.6+/-0.06. 2) The differences between the surface microhardness (DeltaVHN) before and after 30-min treatment were statistically significant among all the groups (P<0.05). According to SEM findings, Morning Care and Condition Power caused showed erosion of enamel surface. However, Dawn 808, which contained Ca (178.9 mg/kg) and fluoride (4.90 ppm), did not erode enamel after immersion for 30 min. CONCLUSIONS: Some hangover-curing beverages with low pH could induce dental erosion on enamel surface.
