Treatment for caries
Pulpectomy is a treatment performed on a primary tooth with extensive decay and involving pulp in the root canal (radicular pulp with irreversible pulpitis or necrosis). The radicular pulp is removed, the pulp canals are filled with a medicament, and a filling is put on the tooth. Medicaments used in pulpectomy include resorbable materials so that they will undergo resorption (dissolution) along with the primary tooth root to allow for proper tooth loss (exfoliation) and replacement with permanent successor teeth.
