Aim: To assess the protective effects of Silver Diamine Fluoride (SDF) against pediatric liquid medicament – induced enamel demineralization of deciduous teeth. Materials and methods: Ninety deciduous incisors were equally divided into three groups of 30 teeth each: without SDF pretreatment (group 1), with SDF pretreatment (group 2) and control group in artificial saliva (group 3). Group 1 and 2 were again divided into 3 subgroups of 10 each, according to the immersion solutions: sodium valproate, salbutamol sulphate and multivitamin. Vickers microhardness was measured at the pre-immersion stage and at regular intervals(7,14,21,28 days). Qualitative analysis was done using Scanning Electron Microscope (SEM) and the values were tabulated for statistical analysis. Results and Discussion: Evaluating the results of hardness tests, all the three medicines investigated could produce evident decrease in Vickers microhardness of all the tested enamel surfaces. Statistically significant erosion occurred (p < 0.05) at all tested days in the multivitamin group, while sodium valproate and salbutamol were able to cause significant change only at the end of the 28 day cycle. The application of 38% SDF on the teeth samples prior to the erosive cycles was able to significantly reduce enamel erosion i.e, the reduction in hardness caused by erosion was statistically lesser in the SDF pretreated group. SEM images after 28 days revealed that all the tested surfaces clearly exhibited structural loss, which was unlike those immersed in artificial saliva. Conclusion: The qualitative and quantitative analysis of enamel samples pretreated with silver diamine fluoride suggested desirable protective effects of SDF on enamel against drug – induced erosive changes.
