RESUMO
AIM: To determine whether a souakine mouth rinse solution can provide protection of deciduous teeth against simulated erosion in vitro. MATERIALS AND METHODS: Thirty deciduous anterior teeth were used. Half of each tooth was covered with a varnish and teeth were randomly divided into a treated (S) and a control group (C). Each group was immersed in cola drink for 5 minutes and treated with an aqueous solution of Souakine (S) or water (C) for 2 minutes. The treatment was renewed 5 times a day for 8 days. Teeth were then embedded, sectioned and observed under polarised light microscope. Observed data were quantitatively analysed by SPSS software. RESULTS: In group (C), the unvarnished part of the enamel showed a deep green layer of erosion, compared to the varnished part. The difference in depth of this layer was significant (p<0.05). In group (S), the green layer of erosion was highly located in the unvarnished part as compared to the unvarnished part of the control group (C) (p<0.05). This layer of erosion was comparable to that in the varnished part, either in control or treated groups. CONCLUSION: The beneficial results of Souakine against erosion are validated either by a protective or a remineralisation effect.
