目的：本研究的目的是确定慢性牙周炎患者磨牙分叉受累的发生率及其相关的临床和影像学表现。材料和方法：在巴西伯南布哥牙周病专业项目（EAP-SCDP-ABO/PE）登记接受治疗的70名年龄在35-69岁的受试者参与了这项研究，共检查了350颗磨牙。临床诊断分叉受累是通过水平Nabers探针进行的，而放射学检查是通过根尖周和咬翼x线片进行的。用3倍放大的x射线观察仪对图像进行分析。采用卡方检验，显著性水平设为5%。结果：共有64.5%的人出现分叉，其中43.1%的人有II度分叉。牙型与分岔受累频率有显著相关性（P = 0.0060）。第一下磨牙和第一上磨牙分别占64.5%和58.5%。临床和x线表现的一致性（0.65）。结论：结合所采用的方法和所获得的结果，可以得出结论：临床和影像学检查是诊断牙周病牙分叉受累的有效工具。
UNLABELLED: Aim : The aim of the present study was to determine the occurrence of furcation involvement in the molars of patients with chronic periodontitis and correlate clinical and radiographic findings.MATERIALS AND METHODS: Seventy subjects aged 35-69 years enrolled for treatment at a periodontics specialization program in Pernambuco, Brazil (EAP-SCDP-ABO/PE) participated in the study, comprising a total of 350 molars examined. The clinical diagnosis of furcation involvement was performed with a horizontal Nabers probe, whereas the radiographic examination was performed with periapical and bite-wing radiographs. The images were analyzed with an X-ray viewer at 3* magnification. The Chi-square test was used, with the level of significance set at 5%.RESULTS: A total of 64.5% individuals presented with furcation involvement, 43.1% of whom had degree II furcation. A significant association (P = 0.0060) was found between tooth type and frequency of furcation involvement. The first lower and upper molars were affected in 64.5 and 58.5% of cases, respectively. Adequate agreement (0.65) was observed between the clinical and radiographic findings.CONCLUSION: Taking into consideration the method employed and the results obtained, it may be concluded that the clinical and radiographic examinations performed are effective tools for diagnosing furcation involvement in teeth affected with periodontal disease.
