Development of an orange juice surrogate for the study of dental erosion

Abstract

The aim of this study was to create a synthetic juice (SJ) to be used as a surrogate for natural orange juices in erosion studies, verifying its erosive potential. The SJ was formulated based on the chemical composition of orange juices from different locations. Forty enamel and 40 root dentin specimens were randomly assigned into 4 experimental groups (n=10): SJ; 1% Citric Acid (CA); Minute Maid Original ® (MM) and Florida Natural Original ® (FN). The specimens were immersed in their respective solutions for 5 min, 6x/day for 5 days, in an erosion-remineralization cycling model. Enamel specimens were analyzed by surface Knoop microhardness and optical profilometry and dentin specimens only by optical profilometry. Outcomes were analyzed statistically by ANOVA followed by Tukey's test considering a significance level of 5%. For enamel, the surface loss and microhardness changes found for MM and SJ groups were similar (p>0.05) and significantly lower (p<0.01) than those found in the CA group. For dentin, CA promoted significantly greater (p<0.01) surface loss compared with all the other groups. No significant difference (p>0.05) was observed in dentin surface loss between MM and SJ. In conclusion, CA was the most erosive solution, and SJ had a similar erosive potential to that of MM natural orange juice.

In Vitro assessment of dentin erosion after immersion in acidic beverages: surface profile analysis and energy-dispersive X-ray fluorescence spectrometry study

“…Traditional assessment techniques, such as microhardness (9,14) and profilometry (15,16), have been applied to evaluate the degradation of dental materials and the loss of dental hard tissue by erosive challenges. EDXRF has been used in several studies to evaluate the content of certain substances on the tooth surface.…”

Protective effect of calcium nanophosphate and CPP-ACP agents on enamel erosion

“…1 Although erosive lesions have a multifactorial etiology, the increasing consumption of acidic food and soft drinks has become an important factor driving their development. [2][3][4] Many strategies have been developed for the prevention and treatment of erosion, and fluoride is the main agent used to enhance enamel remineralization. 5,6 However, to control mineral loss caused by erosion, high concentrations and frequency seem to be needed, because the protective effect of fluoride against demineralization depends on the pH level, F Declaration of Interests: The authors certify that they have no commercial or associative interest that represents a conflict of interest in connection with the manuscript.…”

The effect of Beverages on Color Stability of Highly Impact Acrylic Resin

“…The unaccepted (ΔE) values associated with increasing immersion time might due to increase water sorption which affect the degree of color change (16) because water sorption develop some change in visual appearance (20) . The erosive activity of citric acid that present in Artificial orange juice (pH = 2.66) and natural orange juice (pH = 2.64) might play a role in increasing color change (ΔE) with increasing immersion time intervals (23,24) . Color change (ΔE) after immersion in coffee and tea showed unaccepted values at all immersion time intervals except at (9 hrs) of immersion were the values of ΔE (3,54 and 3, 35) for coffee and tea respectively.…”
