| Summary: | Background: This study aimed to investigate the erosive potential of powdered vitamin C on the bovine enamel tooth surface.
Methods: The experiment included five groups: Lemona, Vitagran, Korea Eundan, Coca-Cola (positive controls), and artificial
saliva (negative controls). The pH and titratable acidity were measured. Bovine enamel specimens were immersed in the
experimental solutions for 15 minutes each day for 7 days. The surface microhardness was measured using the Vickers hardness
number before immersion and on the 1st, 3rd, 5th, and 7th days. The surfaces of the bovine enamel specimens were observed
by scanning electron microscopy (SEM).
Results: The pH of the experimental groups was as follows: Lemona (2.04±0.04) had the lowest pH, followed by Vitagran
(2.56±0.01), the positive control group Coca-Cola (2.60±0.03), Korea Eundan (3.14±0.02), and the negative control group
artificial saliva (7.06±0.05). Surface microhardness decreased significantly during the immersion period (p＜0.001). The largest
surface microhardness reduction value was shown in Lemona (–201.22±20.60), followed by Vitagran (–190.02±14.73), Korea
Eundan (–189.27±27.14), Coca-Cola (–99.28±17.21), artificial saliva (–10.99±9.94). According to the SEM findings, the
experimental and positive control groups exhibited rough surfaces with micropores, whereas the negative control group exhibited
smooth surfaces before specimen immersion.
Conclusion: Consuming powdered vitamin C at a low pH may degrade the enamel surface. To reduce the erosive effect, it is
recommended to rinse the mouth with water and brush the teeth after an hour. |
