The treatment plan for incisor caries is related to the depth of caries, and is generally performed as a decortication filling, a filling after decortication using medication, or a filling after root canal treatment. 1. Decay filling. If the incisors are extracted by clamping or meshing, the decayed tissues are removed directly with specialized instruments and then filled with resin. 2. Medication filling after decay removal. If the incisor caries is already deep caries, it is necessary to use zinc oxide and other medications to fill the filling. If it is reversible pulpitis, it is necessary to use calcium hydroxide and other medications to treat the pulp after removing the caries and then fill the filling. 3. Filling after root canal treatment. If incisor caries has penetrated the pulp, root canal treatment is needed to remove the pulp before filling. To treat incisor caries, it is necessary to determine the state of the pulp before making the appropriate treatment plan, so please consult a professional physician.
