Abstract

Purpose: The objective of the present in vitro study was to evaluate the effect of different minerals in combination with 1% citric acid on dental erosion. Materials and Methods: Ninety enamel samples were randomly allocated to nine groups (G1. pure 1% citric acid solution {[}control]. G2. with 1 mM Ca: G3 with 0 047 mM F, G4. with 1 mM Fe. G5. with 1 mM P, G6 with 1 mM Ca and 0 047 mM F. G7. with 1 mM Ca and 1 mM P: G8: with 1 mM Fe and 0.047 mM F, G9. with 1 mM Ca, 1 mM P. 0 047 rnM F and 1.0 mM Fe) The samples were subjected to six pH cycles, each consisting of immersion in pure or modified 1% citric acid (1 min) followed by storage in artificial saliva (59 min) Enamel wear was assessed using profilometry. Results: Data were analysed using analysis of variance and Tukey test (P < 0 05) Enamel loss (mean +/- SD) amounted to between 0 87 +/- 0 30 and 1 74 +/- 0 74 mu m but did not significantly differ among the groups Conclusions: The modification of 1% citric acid with different minerals did not have a protective effect on enamel erosion (AU)
