A Comparative Evaluation of the Effects of Three Remineralizing Agents on Bleached Enamel: A Scanning Electron Microscopy (SEM) Analysis

With the emerging concern of patients on esthetics, bleaching has become quite popular to get that "Shining White Smile." However, bleaching chemicals used on enamel's surface have been a clinical issue due to the fact that they might cause a variety of side effects, including sensitivity, gingival irritation, dentinal sensitivity, demineralization, and changes in the enamel's surface morphology. As a result, it is important to investigate different remineralizing agents that help to reduce the adverse effects. The researchers in this in-vitro study used a scanning electron microscope (quanta 200 SEM, California, USA) and a universal testing machine to assess the effects of three remineralizing products such as Tooth Mousse Plus (GC Corporation, India), Tooth Min (Abbott, India), and Elsenz (Group Pharmaceuticals Ltd, India) on bleached enamel. Based on the data available, we determined that bleaching greatly reduces the enamel microhardness of permanent human premolars; however, this loss could be recovered with a remineralizing agent. Tooth Mousse Plus is the most effective remineralizing agent among the three, followed by Elsenz and, finally, Tooth Min.
