Pulpotomy for pulpitis is the first step in root canal treatment. For patients with pulpitis, pulpotomy is typically performed under local anesthesia using pulp extraction tools to remove the pulp, including the crown pulp or root pulp, or an inactivator is sealed into the pulp chamber, and the pulp gradually necrotizes after a week. At this point, the root canal is cleaned, and the infected and necrotic tissues between the pulp chambers are prepared with root canal files to meet the treatment standards. The root canal is then filled with gutta-percha points, filling into the pre-prepared root canal until it is full, followed by filling the crown and shaping the exterior. Generally, the root canal treatment process requires two to three sessions to complete. During the acute phase, the pulpotomy is usually left open for treatment right after, and it is recommended to take anti-inflammatory medication for two to three days. After the tooth pain eases, the root canal cleaning is then carried out. Thus, it is important to maintain oral hygiene regularly, brush teeth in the morning and evening, and rinse after meals. It is vital to detect and treat dental caries early.
