摘要:

目的 评价锥形束CT (CBCT)在上颌磨牙根分叉病变诊断中的准确性。方法 纳入经过基础治疗后需行根分叉区翻瓣手术的慢性牙周炎患者15例,共31颗上颌磨牙,术前进行临床探诊和CBCT检查,比较术中探诊与临床探诊和CBCT检查所得根分叉病变分度的一致性。结果 临床检查与术中检查所得根分叉病变分度在颊侧、近颊腭侧、远颊腭侧一致性均较差,κ值均小于0.4,完全一致率仅为42.0%,多数病变被高估(24.7%)或者被低估(33.3%)。而CBCT与术中检查所得根分叉病变分度一致性较高(κ=0.831),完全一致率高达88.2%,仅有少数病例被高估(3.2%)或者低估(8.6%),不同位置一致性比较结果为颊侧(κ=0.896)>远中腭侧(κ=0.822)>近中腭侧(κ=0.767)。结论 CBCT可以很好地反映上颌磨牙根分叉病变的水平骨缺损情况。

Abstract:

Objective This study aimed to assess the accuracy of cone beam computed tomography (CBCT) in detecting furcation involvement (FI) in maxillary molars. Methods Thirty-one maxillary molars of 15 patients with generalized chronic periodontitis considered for furcation surgery were assessed. Clinical examination and CBCT were performed, and the FI degree was evaluated. Clinical and CBCT-based FI assessments were compared with intrasurgical data. Results The agreement between clinical and intrasurgical assessments was weak in all sites, with a kappa of less than 0.4; the complete, overestimated, and underestimated agreement percentages were 42.0%, 24.7%, and 33.3%, respectively. The agreement between the CBCT and intrasurgical assessments was strong, with a kappa of 0.831; the complete, overestimated, and underestimated agreement percentages were 88.2%, 3.2%, and 8.6%, respectively. The agreement between both assessments was the highest in the buccal furcation entrance (κ=0.896), followed by that in the distopalatal (κ=0.822) and mesiopalatal (κ=0.767) furcation entrances. Conclusion CBCT images demonstrated high accuracy in assessing the horizontal bone loss of FI in maxillary molars.
