Effect of Nitrofurantion Used as an Intracanal Medicament

Nitrofurantoin has been used as a treatment for UTI since the 1950s. Evidence suggested that nitrofurantoin has excellent safety profile and lower resistance rates compared to recently introduced antimicrobials, recommending it as the first-line agent. Nitrofurantoin is convert to reactive intermediates by bacterial Nitroreductases. These intermediates were shown to attack bacterial ribosomal proteins non-specifically, causing complete inhibition of protein synthesis. In MIC, Nitrofurantoin specifically inhibit enzyme synthesis in bacteria (24). The lack of clinically significant bacterial resistance development to Nitrofurantoin is likely due to the multiple sites of attack and multiple mechanisms of action. Achievement of high local levels and low serum concentrations, and its effectiveness against both gram-negative and gram-positive bacteria provide many advantages that many of the newer agents do not have. After searching the database there is no clinical studies found yet on the effect of Nitrofurantoin antibiotic used as intracanal medicament in teeth with necrotic pulp. The aim of this study is to clinically evaluate the effect of Nitrofurantion on Intensity of Postoperative Pain and Bacterial Load Reduction, when compared to calcium hydroxide in teeth with necrotic pulp.
