Schematic diagram of the current concept of pulp therapy. (A) Direct pulp capping. Pulp capping is a method used to prevent necrosis of the dental pulp when it is slightly exposed to the pin-point. Direct pulp capping covers the exposed dental pulp with a base that protects the pulp and prevents infection to maintain dental pulp vitality. (B) Pulpotomy. Pulpotomy is a minimally invasive method that is clinically considered when there is pulpitis in the absence of root pathology. (C) Pulpectomy. Pulpectomy refers to a root canal treatment that removes irreversibly infected or necrotic pulp tissue.
