A pulpotomy is a dental procedure to remove decayed or inflamed pulp from the crown of a tooth, preserving the healthy pulp in the roots. This minimally invasive treatment is commonly performed on children's primary teeth with deep decay but no root pathology, aiming to maintain tooth vitality and facilitate proper permanent tooth eruption. The procedure involves numbing the tooth, removing the infected pulp, applying a medicated material, and restoring the tooth with a filling or crown to seal the space.
