Pulpectomy is indicated where the pulp is either non-vital or irreversibly inflamed. Although the technique is often considered difficult because of the complexity of the root canals in primary molars, clinical studies have shown a reasonable prognosis.The cavity preparation and removal of the necrotic coronal pulp is carried out as previously described. If the radicular pulp is necrotic, a two-stage procedure is required, but if it is found to be irreversibly inflamed a one-stage technique may be undertaken.
