<prompt> The first step in treating rampant caries:Application of topical fluoride to all affected teethRestoring all teeth with stainless steel crownExcavation of softened tooth structure and filling with zinc oxide eugenolPerforming oral prophylaxis and instructions about oral hygiene  <response>: Zinc oxide acts as obtundant. It also significantly reduces the bacteriological count in oral cavity.When rampant caries occurs, the first step is to initiate treatment of all carious lesions, to stop or at least slow the progression of the disease and to identify the most important causes of the existing condition. If the restorative care is to be performed over several visits in the outpatient setting, gross caries excavation as an initial approach in the control of rampant dental caries has several advantages. The removal of superficial caries and the filling of the cavity with a glass ionomer material or zinc oxide-eugenol cement IRM will at least temporarily arrest the caries process and prevent its rapid progression to the dental pulp.
