2、导入根管闭塞处进行根管预备,或根管内暂封EDTA一周后再进行根管预备。而B组62例72颗后磨牙,82个钙化闭塞根管采用氯亚明配合根管预备;然后依据X线片及临床检查评价根管预备效果。结果:A组83个钙化闭塞根管中有72个根管扩通,预备完好,成功率为86.75%。B组82个钙化闭塞根管中仅有18个根管扩通,成功率为21.95%,且断针率增加,比较差异有统计学意义(P3、cationResearchintheCalcifiedBlockRootCanalPreparationoftheBackTeeth/LUShan,HUANGZhao—yi,GUOHong—jianJ/MedicalInnovationofChina.2013.10(34):039-040【AbstractlObjective:Thecalcifiedblockrootcanalshavegreatlyinfluencedthecurativeefecttotherootcanals.Toobse4、rvetheEDTApasteintheapplicationofcalcifiedblockrootcanalpreparation,evaluateitsclinicalefficacy.Method:Onehundredandtwenty—fourpatientsinourdepartmentfromMarch2009toMarch2012wereselected,140backmolarteeth,165calcifiedblockrootcanalsandthendividethemran5、domlyintothegroupAandthegroupB,62casesineachgroup.Therewere62cases,68backmolarteethand83calcifiedblockrootcanalsinthegroupA.ThegroupAwastreatedwiththeEDTApasteintorootcanalocclusionforrootcanalpreparation,ortemporarysealrootcanalEDTArootcanalpreparatio6、naweeklater.Therewere62cases,72backmolarteethand82calcifiedblockrootcanalsinthegroupB.ThegroupBwastreatedwithchloramineintothecalcifiedblockrootcanalsandthenhadarootcanalpreparation.ThepreparatoryeffectoftherootcanalsaccordingtotheX—rayandclinicalexami7、nationwereevaluated.Result:Eighty-threecalcifiedblocklOOtcanalinthegroupAwith72rootcanalexpansion,preparedwell,theSuccessratewas86.75%.82calcifiedblockrootcanalinthegroupBonly18rootcanalinrootcanalexpansion,theSuccessratewas21.95%,andthebreakagerateinc8、reased,thediferencewasstatisticallysignificant(P<0.01).Conclusion:TheeffectthatEDTApastehasbeenusedinthecalcifiedblockrootcanalsisverygood.Itcanraiseremarkablythesuccessfulrateofrootcanalpreparation.【Keywords】Rootcanalpreparation;Calcif
