These techniques involve the removal of inflamed coronal pulp tissue and the application of a dressing to the radicular pulp in an attempt to either promote healing of, or fix, the upper portions, and to preserve the vitality of the apical tissue. Because of the difficulties involved in diagnosing the condition of the pulp tissue histologically before the commencement of treatment, careful assessment must be made at each stage of the procedure. Whenever the haemorrhage from the radicular pulp stumps is profuse and uncontrolled, the assumption is made that the inflammatory process has extended into the radicular tissue, and the therapy modified accordingly. There are three pulpotomy techniques.
