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.
RESUMO
O objetivo deste estudo foi criar um suco sintético (SJ) para ser usado como substituto do suco de laranja natural em estudos de erosão dental, verificando o seu potencial erosivo. O SJ foi formulado com base na composição química de sucos de laranja de diferentes locais. Quarenta espécimes de esmalte e 40 de dentina radicular foram aleatoriamente alocados em 4 grupos experimentais (n=10) SJ; 1% Citric acid (CA); Minute Maid Original® (MM) e Florida Natural Original® (FN). Os espécimes foram imersos nas suas respectivas soluções por 5 min, 6x/dia por 5 dias, em um modelo de ciclagem de erosão-remineralização. Os espécimes de esmalte foram analisados por microdureza de superfície Knoop e perfilometria ótica, enquanto que os espécimes de dentina foram analisados somente por perfilometria. Os resultados foram analisados estatisticamente com o teste de ANOVA, seguido pelo teste de Tukey, considerando um nível de significância de 5%. Para o esmalte, a perda superficial e as alterações de microdureza encontradas para os grupos MM e SJ foram similares (p>0,05) e significantemente menores (p<0,01) do que as encontradas para o grupo CA. Para dentina, CA promoveu significantemente (p<0,01) a maior perda de superfície quando comparada aos outros grupos. Não foram encontradas diferenças significantes (p>0,05) entre a perda de superfície de dentina dos grupos MM e SJ. Concluiu-se que CA foi a solução mais erosiva e SJ apresentou um potencial erosivo semelhante ao do suco de laranja natural MM.
