摘要
目的 评价锥形束CT在辅助诊断慢性牙周炎牙槽骨缺损中的准确性及其与根尖X线片、曲面体层X线片和临床检查结果的一致性,以期为锥形束CT在辅助诊断慢性牙周炎骨缺损中的应用提供依据.方法 采用单纯随机抽样法纳入2012年12月至2013年12月就诊于西安交通大学医学院附属口腔医院牙周黏膜科并确诊为慢性牙周炎的患者75例,分别进行锥形束CT、根尖X线片及曲面体层X线片检查,用华海MedViewer及EzlmPlant软件测量牙槽骨缺损的高度,同时行全口牙周探诊检查,确定附着丧失水平及釉质牙骨质界至牙槽嵴顶的距离,作为影像学检查结果的临床评判指标.对临床测量值及锥形束CT测量牙槽骨的缺损值行配对t检验,采用单因素方差分析评价4种方法检测近远中牙槽骨缺损的结果,以P<0.05为差异有统计学意义.结果 共纳入1 494颗牙,8 964个位点,3种影像学方法中仅锥形束CT可以检测出唇(颊)或舌(腭)侧牙槽骨破坏;对近远中向牙槽骨缺损的测量结果显示,锥形束CT[近中:(5.5±0.4)mm,远中:(5.6±0.8)mm]与根尖X线片[近中:(5.1±0.6)mm,远中:(5.1±0.8)mm]、锥形束CT与全口曲面体层X线片[近中:(4.9±0.4)mm,远中:(4.9±0.8)mm]的测量结果相比差异均有统计学意义(P值均<0.01),临床探诊[近中:(5.5±0.6)mm,远中:(5.5±0.6)mm]与根尖X线片及全口曲面体层X线片相比差异亦有统计学意义(P值均<0.01),但临床探诊与锥形束CT的测量结果相比差异无统计学意义;锥形束CT与临床探诊对不同区域1 494颗牙齿牙槽骨缺损差异的检出情况一致,两种方法检测不同区域牙齿及1 494颗牙不同位点的牙槽骨缺损差异均无统计学意义(P值均>0.05),两种方法不存在牙位及位点差异性.结论 锥形束CT与临床探诊在评价不同牙位及不同位点的牙槽骨缺损中一致性最高;锥形束CT在判断慢性牙周�
Objective To evaluate the accuracy of cone-beam CT(CBCT) for detection of bone defects in chronic periodontitis and its consistency with periapical film,panoramic radiograph and clinical examination.Methods Seventy-five patients with periodontitis were selected in the study.Each patient received clinical examination,periapical film,panoramic radiograph and CBCT examination one week after supragingival scaling.The distance from the alveolar ridge crest to enamelo-cemental junction was measured.The data were statistically analyzed.Results A total of 1 494 teeth and 8 964 sites were included in the study.Among the three kinds of imaging methods only CBCT could detect the lip(buccal) or tongue(palatine) side of alveolar bone destruction.Compared with panoramic radiographs[mesial:(4.9:±:0.4) mm,distal:(4.9±0.8) mm] and periapical film[mesial:(5.1 ±0.6) mm,distal:(5.1±0.8) mm],CBCT[mesial:(5.5± 0.4) mm,distal:(5.6±0.8) mm] showed significant differences(P<0.01) in alveolar bone defect measurements in detecting mesial and distal alveolar bone defect.There was no significant difference between clinical probing [mesial:(5.5±0.6) mm,distal:(5.5±0.6) mm] and CBCT.Conclusions CBCT have the highest consistency with clinical probing in detecting the alveolar bone loss in chronic periodontitis.
