Pulpotomy is performed when the inflammation is confined to the coronal pulp. If the inflammation is mainly confined to the coronal pulp, the inflamed pulp of the crown can be removed and the wound can be covered with a special pulp-covering material to preserve the normal pulp tissue to perform its normal physiological function and promote further development of the root, and patients are generally advised to review the procedure regularly at 3 months, 6 months, 1 year and 2 years. If partial necrosis of the root pulp is found in the tooth undergoing live pulpotomy, apical induction molding is required for the affected tooth. There are two types of recovery from live pulpotomy, as follows: 1) successful live pulpotomy with preservation of root pulp viability; 2) failure, where the operation has been performed with a root canal microscope, but it is not possible to determine whether the bacterial infectious material has penetrated into the root pulp. If it has spread to the root pulp, it is possible that the live pulpotomy is a failure and apical induction molding may be required.
