Abstract
In general, the treatment of dentin hyperesthesia can be performed either at home or in the dentist’s office. The therapeutic approach aims at the use of products, which decrease the excitability of pulp nociceptors or reduce the permeability of the dentin canals. The purpose of this study is to compare the efficiency in the treatment of dentin hyperesthesia of a product containing potassium nitrate, compared to another product using Recaldent™ Technology. The results of this study indicated a significant decrease in pain sensitivity both after application of the product using Recaldent™ Technology and after the product containing potassium nitrate, the results being slightly in favour of the first product.
