Abstract :
Objective. This paper aimed to analyze the in vitro industrialized fruit juices effect plus soy to establish the erosive potential of these solutions. Materials and Methods. Seventy bovine incisors were selected after being evaluated under stereomicroscope.Their crowns
were prepared and randomly divided into 7 groups, using microhardness with allocation criteria. The crowns were submitted to the fruit juice plus soy during 15 days, twice a day. The pH values, acid titration, and Knoop microhardness were recorded and
the specimens were evaluated using X-ray microfluorescence (𝜇XRF). Results. The pH average for all juices and after 3 days was
significantly below the critical value for dental erosion. In average, the pH value decreases 14% comparing initial time and pH after
3 days. Comparing before and after, there was a 49% microhardness decrease measured in groups (𝑝 < 0.05). Groups G1, G2,
G5, and G6 are above this average. The analysis by 𝜇XRF showed a decrease of approximately 7% Ca and 4% P on bovine crowns
surface. Florida (FL) statistical analysis showed a statistically significant 1 difference between groups. Thus, a tooth chance to suffer demineralization due to industrialized fruit juices plus soy is real.
