Intraoral pacification treatment refers to the treatment of pacifying the dental nerve, which is usually applied to patients with deep cavities. When the doctor carries out filling treatment, if the patient has relatively obvious irritation pain, at this time, it is possible not to give filling and consider pulp pacification treatment with zinc oxide and other drugs. If the filling is done rashly, it is likely that the filling will lead to significant cold or hot irritation pain or the patient will not dare to bite after the filling. The first layer can use calcium hydroxide, which has the effect of promoting the formation of dentin restorations, and then use 3M glass ionomer in the upper part, which can isolate the resin material for the pulp stimulation.
