摘　　要：目的　观察氢氧化钙根管内封药、引导性组织再生术 ( guidedtissueregeneration ,GTR)和高压氧(hyperbaricoxyen ,HBO)治疗联合应用对再植牙的疗效。 方法　选择脱位时间超过 6小时的 35 8颗前牙 ,随机分成实验组和对照组 ,前者以Ca(OH) 2 根管内封药后在再植术中配合使用不全胶原膜行GTR术 ,术后给予HBO治疗10天 ;后者常规根管充填后进行常规牙再植术。对两组手术后临床指标和牙根吸收及失牙情况进行跟踪观察并分析其原因。结果　术后 3、6、12个月实验组探诊深度减少和附着获得与对照组差异显著 ;牙根吸收率、2年失牙率和再植牙总成功率两组亦有非常明显的差异。结论　配合Ca(OH) 2 根管内封药和GTR、HBO治疗可使脱位离体时间较长牙再植术获得较好疗效。ObjectiveTo evaluate the effectiveness of calcium hydroxide,intracanal medicament,guided tissue regeneration(GTR) and hyperbaric oxygen(HBO) in the treatment of replanted tooth.MethodsA total of 266 luxational teeth were divided into 2 groups,the expriment group and the control group.The experiment group was undergoing Ca(OH) 2 intracanal medicament and then replanted,GTR was performed on each tooth.After replantaion,patients were exposed to 0.25Mpa pure oxygen 40×2 minutes each day and treated 10 days continuesly.The control group was compared.Clinical measurements and radiography were used to evaluate the effect.ResultsClinical measurements showed significant attachment gained,significant decrease of probing depth(PD) of the two groups.The mean PD of the experiment group decreased by 1.5 mm, 2.5 mm, 3.5 mm at 3 mouth,6 mouth and 12 mouth,attachment gain by 1.8 mm, 2.4 mm, 3.7 mm,which showed statistical significant differences compared to the control group.The rate of root resorption,missing tooth and total effective of experiment group was 35.71%, 5.49%, 91.76%.ConclusionGood resalts can be achieved with use of Ca(OH) 2,GTR and HBO in the treatment of replanted teeth.
