高压氧用于年轻恒牙再植术的临床研究

Clinnical studies on the use of hyperbaric oxygen in replantation of young permanent teeth

目的 探讨年轻恒牙脱位再植后 ,高压氧 (hyperbaricoxygen ,HBO)治疗对牙髓牙周损伤修复的作用。方法 对 6 9例年轻恒前牙脱位患者的 138颗患牙行再植术 ,术后分为HBO组和对照组 ,HBO组给予HBO治疗 10d ,对照组不给予HBO治疗 ,进行对照。结果 HBO组和对照组的牙再植总成功率分别为 97 2 6 %和 70 77% ,二者差异有显著性 (P <0 0 5 ) ;1年后失牙情况 :HBO组 1颗(1 37% ) ,对照组 12颗 (18 46 % ) ,两组失牙率差异有极显著性 (P <0 0 0 1)。结论 HBO对保存脱位年轻恒牙活髓、减少牙根吸收和防止再植牙松动有显著作用 。

Objective To investigate the treatment effects of hyperbaric oxygen(HBO) in replantation of young permanent teeth Methods A total of 138 luxation injuries to young permanent teeth undergoing treatment The teeth were replanted and then divided into 2 groups The HBO group was exposed to 0 25 MPa pure oxygen 40×2 minutes each day for 10 days continuosly while the control group were compared Results The totle effective rates of the HBO group and the control group were 97 26% and 70 77% respectively, and showed significant difference ( P <0 05); respective frequencies of missing tooth after 1 year were 1 37 % and 18 46%, and provided a statistical significance ( P <0 001) Conclusion HBO used in replantation of luxated young permanent teeth could promote the recovery of periodontal membrance, pulp, and prevent resorption of root
