简介:摘要目的研究牙周牙髓联合病变与牙周感染的相关性.方法回顾性分析2011年4月至2013年3月我院共收治50例(50颗牙)牙周牙髓联合病变患者的临床资料.结果观察组中23例患者检出致病菌,27例患者未检出致病菌,阳性率为46%;对照组中所有患者均没有检出致病菌,阳性率为0.主要病原菌包括牙龈卟啉单胞菌、齿垢螺旋体、福赛类杆菌等.观察组患者的阳性率明显比对照组高(P<0.05).结论牙周牙髓联合病变的一个重要症状就是牙周感染,临床可将牙周感染作为诊断牙周牙髓联合病变的主要依据.关键词牙周牙髓联合病变;牙周感染;相关性CorrelationbetweenPeriodontalEndodonticLesionsandPeriodontalInfectionLinJianqinTianFuming?(StomatologyDepartment,HubeiProvincialMedicalCollegePeople'sHospital)AbstractObjectiveTostudythecorrelationbetweenperiodontalendodonticlesionsandperiodontalinfection.MethodsTheclinicaldataof50cases(50teeth)ofperiodontal-endodonticlesionspatientswhohadbeentreatedinourhospitalfromApril2011toMarch2013wereretrospectivelyanalyzed.ResultsIntheobservationgroup,23casesweredetectedwithpathogens,27caseswerenotdetectedwithbacteria,thepositiveratewas46%;Inthecontrolgroup,allpaGtientshadnodetectablepathogens,thepositiveratewas0.ThemainpathogensincludedPorphyromonasgingivalisAeromonas,tartarspirochetes,Bacteroidesforsythusandsoon.Thepositiverateoftheobservationgroupwassignificantlyhigherthanthatofthecontrolgroup(P<0.05).ConclusionOneimportantsympGtomofperiodontalendodonticlesionsisperiodontalinfection,theclinicalmayregardperiodontalinfectionasamainbasisinthediagnosisofperiodontalendodonticlesionsK.eywordsPeriodontalendodonticlesions;Periodontalinfection;Correlation中图分类号R781.0文献标识码B文章编号1008-6315(2015)10-0291-02
