The effects of vital root resection upon the remaining pulp were studied in twenty-six periodontally involved human molars. The pulp was extirpated 14 days after the intervention. Granulomatous tissue present in the pulp chamber protruded from the site of the exposure as a polyp in eleven cases. Mild chronic inflammatory changes were present in the coronalmost part of the radicular pulp. The apical pulp was not affected at this time interval.
在26颗患有牙周炎的人类磨牙上研究了活髓牙根切除术对剩余牙髓的影响。干预14天后摘除牙髓。在11例病例中，牙髓腔内存在的肉芽肿组织从暴露部位突出形成息肉。在牙根牙髓的最冠部存在轻度慢性炎症改变。在此时间间隔内，根尖部牙髓未受影响。
