目的 探讨锥形束CT(CBCT)在诊断老年牙周炎骨丧失程度中的应用价值. 方法 对27例牙周炎患者的38颗患牙进行CBCT和X线根尖片检查,检测牙槽骨吸收位点,并对骨缺损进行线性测量,所有患者均行牙周翻瓣手术治疗,并以术中实际检测到的牙槽骨丧失位点数以及牙槽骨高度丧失测量值作为对照金标准. 结果 CBCT对骨缺损位点的诊断与翻瓣术中所见完全一致,准确率达100.0% (72/72);而X线根尖片仅能检测出近远中骨缺损位点,不能检测出颊舌侧骨缺损位点,准确率为62.5%(45/72).CBCT测量的牙槽骨高度丧失值与术中测量值分别为(5.516±0.393) mm与(5.385±0.415) mm,差异无统计学意义(t=1.948,P>0.05),而X线根尖片分别为(6.311±0.439)mm与(5.411±0.418) mm,差异有统计学意义(t=9.956,P<0.05). 结论 CBCT能够为老年牙周炎骨缺损提供三维方向的诊断信息,对各个方位的牙槽骨吸收提供客观准确的评价,并具有更高的准确性和可靠性.
目的 探討錐形束CT(CBCT)在診斷老年牙週炎骨喪失程度中的應用價值. 方法 對27例牙週炎患者的38顆患牙進行CBCT和X線根尖片檢查,檢測牙槽骨吸收位點,併對骨缺損進行線性測量,所有患者均行牙週翻瓣手術治療,併以術中實際檢測到的牙槽骨喪失位點數以及牙槽骨高度喪失測量值作為對照金標準. 結果 CBCT對骨缺損位點的診斷與翻瓣術中所見完全一緻,準確率達100.0% (72/72);而X線根尖片僅能檢測齣近遠中骨缺損位點,不能檢測齣頰舌側骨缺損位點,準確率為62.5%(45/72).CBCT測量的牙槽骨高度喪失值與術中測量值分彆為(5.516±0.393) mm與(5.385±0.415) mm,差異無統計學意義(t=1.948,P>0.05),而X線根尖片分彆為(6.311±0.439)mm與(5.411±0.418) mm,差異有統計學意義(t=9.956,P<0.05). 結論 CBCT能夠為老年牙週炎骨缺損提供三維方嚮的診斷信息,對各箇方位的牙槽骨吸收提供客觀準確的評價,併具有更高的準確性和可靠性.

Objective To evaluate the accuracy and reliability of cone-beam computed tomography (CBCT) in the diagnosis of periodontal bone defects in the elderly.Methods The 38 teeth of 27 cases were collected and scanned both with CBCT technology and periapical radiography (PA).Periodontal bony defects were identified and linear measurements were made for all defects.All cases were treated with periodontal flap surgery with the bony defects and their linear measurements detected during operation as the gold standard.Results All periodontal bony defects were identified with CBCT with its accuracy rate of 100.0% (72/72),but the buccal and lingual defects could not be measured by PA with its accuracy rate of 62.5% (45/72).Linear measurements for all defects revealed no statistical differences between CBCT and direct measurement [(5.516 ± 0.393) mm vs.(5.385± 0.415) mm,t=1.948,P>0.05],but there was a significant difference in linear measurement between PA and direct measurement [(6.311±0.439) mm vs.(5.411±0.418) mm,t=9.956,P<0.05].Conclusions CBCT can offer the diagnostic information for periodontal bone defect from three dimensional direction in the elderly,provide objective and accurate assessment of alveolar bone resorption,and has higher accuracy and reliability.
