Abstract：
UNASSIGNED: The objectives were to clarify if intraoral ultrasonography (USG) is: (1) more accurate than conventional periodontal examinations in detection of furcation involvement, and (2) comparable to conventional periodontal examinations in accurate horizontal classification of furcation involvement in comparison to cone beam computed tomography (CBCT).
UNASSIGNED: The buccal furcation in 61 lower first molars were evaluated with conventional periodontal examinations, intraoral USG and CBCT. The presence and classification of the horizontal depth of furcation involvement were defined clinically by assessment with a Nabers periodontal probe and a periapical radiograph with reference to the bone loss under the fornix. The horizontal depth of furcation involvement was measured in intraoral USG and CBCT images. Based on the measurements, presence diagnosis and horizontal classification were performed. Results from conventional periodontal examinationsand intraoral USG were compared with those from CBCT.
UNASSIGNED: κ value (κ) for agreement of presence diagnosis of furcation involvement between intraoral USG and CBCT was 0.792, while agreement with conventional periodontal examinations was 0.225. Diagnostic accuracy of intraoral USG exhibited higher values (sensitivity: 98.3%, accuracy: 98.4 %) than conventional periodontal examinations (81.4% and 81.9 %). Weighted κ statistics showed substantial agreement in the classification between intraoral USG and CBCT (κ = 0.674). High agreement (ICC: 0.914) for the measurement of horizontal depth of furcation involvement was found between intraoral USG and CBCT.
UNASSIGNED: Intraoral USG may be a reliable diagnostic tool for assessment of furcation involvement of mandibular molars with a similar performance to CBCT, but without ionizing radiation.

摘要：
■目的是澄清口内超声检查（USG）是否：（1）在检测分叉受累方面比常规牙周检查更准确，（2）与锥形束计算机断层扫描（CBCT）相比，在分叉受累的准确水平分类方面与常规牙周检查相当。
■用常规牙周检查评估了61颗下第一磨牙的口腔分叉，口内USG和CBCT。通过使用Nabers牙周探针和根尖周X光片评估，并参考穹窿下的骨丢失，在临床上定义了分叉受累的水平深度的存在和分类。在口内USG和CBCT图像中测量分叉受累的水平深度。根据测量结果,进行存在诊断和水平分类.将常规牙周检查和口内USG的结果与CBCT的结果进行了比较。
■口内USG和CBCT之间分叉受累的诊断一致性的κ值（κ）为0.792，而与常规牙周检查的一致性为0.225。口内USG的诊断准确性显示出较高的值（敏感性：98.3％，准确性：98.4％）比常规牙周检查（81.4％和81.9％）。加权κ统计量显示口腔内USG和CBCT之间的分类基本一致（κ=0.674）。在口腔内USG和CBCT之间发现了高度一致性（ICC：0.914）的水平分叉深度测量。
■口内USG可能是评估下颌磨牙分叉受累的可靠诊断工具，其性能与CBCT相似，但没有电离辐射。
