The author reports about the clinical and X-ray study of 25 patients who were replanted 25 teeth in two stages -- 12 teeth of the upper and 13 of the lower jaw-during acute and exacerbated periodontitis. Lyophilized spongiosis chips were deposited in the alveoli before the replantation of 5 teeth. During the first stage, the extracted tooth is mechanically cleaned, washed with hudrogen peroxide and alcohol and then preserved in a solution of penicillin and physiological salt solution in the refrigerator at a temperature from +2 to +5 degrees C. During the second stage, the tooth is taken from the refrigerator after two to five 24-hours, obturated and replanted. The results allowed the conclusion that the method could be applied only in exceptional cases. The use of lyophilized spongiosis chips in replantation of teeth should be studied thoroughly in the future, presuming that it will contribute to the longer-term survival of replanted tooth.
作者报告了25例患者的临床和X线研究情况，这些患者在急性和加重期牙周炎期间分两阶段再植了25颗牙齿——上颌12颗，下颌13颗。在5颗牙齿再植前，将冻干海绵化碎屑植入牙槽窝。在第一阶段，将拔出的牙齿进行机械清洁，用过氧化氢和酒精冲洗，然后保存在青霉素和生理盐溶液中，置于冰箱中，温度为+2至+5摄氏度。在第二阶段，两到五个24小时后从冰箱中取出牙齿，进行根管充填并再植。结果表明，该方法仅适用于特殊情况。冻干海绵化碎屑在牙齿再植中的应用今后应进行深入研究，假定其将有助于再植牙齿的长期存活。
