牙周病医生在准确评估和治疗受牙周病影响的分叉区域时经常遇到不便。分叉受累 (FI) 最常影响下颌磨牙。涉及分叉的牙齿的诊断主要通过探诊深度、临床附着水平、分叉入口探诊和口内根尖周X线片的评估。三维成像为临床医生评估骨形态提供了优势。因此，本研究旨在比较锥形束计算机断层扫描 (CBCT) 与直接术中测量下颌磨牙分叉缺陷的诊断效果。研究人群包括 14 名具有 25 个下颌磨牙分叉部位的患者。采用CBCT测量FI级II级和III级下颌磨牙分叉缺损的高度、宽度和深度。在牙周瓣手术期间对指定牙齿进行 FI 的术中测量，并将其与 CBCT 测量进行比较。使用配对 t 检验和 Bland-Altman 图进行统计分析。 CBCT 与术中分叉测量结果分别为：分叉高度为 2.18 ± 0.86 mm 和 2.30 ± 0.89 mm，分叉宽度为 1.87 ± 0.52 mm 和 1.84 ± 0.49 mm，分叉深度为 3.81 ± 1.37 mm 和 4.05 ± 1.49 mm。结果显示，测量参数之间没有统计学意义，表明两种方法在统计上相似。 CBCT 评估下颌磨牙 FI 的准确性与直接手术测量的准确性相当。这些发现表明 CBCT 是牙周治疗计划中极好的辅助诊断工具。
Periodontists frequently experience inconvenience in accurate assessment and treatment of furcation areas affected by periodontal disease. Furcation involvement (FI) most commonly affects the mandibular molars. Diagnosis of furcation-involved teeth is mainly by the assessment of probing pocket depth, clinical attachment level, furcation entrance probing, and intraoral periapical radiographs. Three-dimensional imaging has provided advantage to the clinician in assessment of bone morphology. Thus, the present study aimed to compare the diagnostic efficacy of cone-beam computed tomography (CBCT) as against direct intrasurgical measurements of furcation defects in mandibular molars. Study population included 14 patients with 25 mandibular molar furcation sites. CBCT was performed to measure height, width, and depth of furcation defects of mandibular molars with Grade II and Grade III FI. Intrasurgical measurements of the FI were assessed during periodontal flap surgery in indicated teeth which were compared with CBCT measurements. Statistical analysis was done using paired t-test and Bland–Altman plot. The CBCT versus intrasurgical furcation measurements were 2.18 ± 0.86 mm and 2.30 ± 0.89 mm for furcation height, 1.87 ± 0.52 mm and 1.84 ± 0.49 mm for furcation width, and 3.81 ± 1.37 mm and 4.05 ± 1.49 mm for furcation depth, respectively. Results showed that there was no statistical significance between the measured parameters, indicating that the two methods were statistically similar. Accuracy of assessment of mandibular molar FI by CBCT was comparable to that of direct surgical measurements. These findings indicate that CBCT is an excellent adjunctive diagnostic tool in periodontal treatment planning.
