Title:  Souakine mouth rinse solution protects deciduous enamel from simulated erosion in vitro

Abstract:  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. Conclusions The beneficial results of Souakine against erosion are validated either by a protective or a remineralisation effect.
