本研究的目的是比较临床睡眠磨牙症（SB）诊断与仪器诊断获得的设备提供肌电图/心电图（EMG/ECG）记录。从都灵大学牙科学院颌外科的患者中选择了45名（N = 45）受试者（19名男性和26名女性，平均年龄28 ± 11岁）。专家临床医生根据一种或多种体征/症状的存在（即早晨一过性颌肌疼痛、醒来时肌肉疲劳、牙齿磨损、咬肌肥大）评估SB的存在。此外，所有参与者都在家中使用便携式设备（Bruxoff（R）; OT Bioelettronica，都灵，意大利）进行仪器记录，可以同时记录来自咬肌的EMG信号以及心率。使用软件Statistical Package for the Social Science v.20.0（SPSS 20.0（R）; IBM，Milan，意大利）进行统计程序。基于EMG/ECG分析，26名受试者（11名男性，15名女性，平均年龄28 +/-10岁）被诊断为睡眠磨牙者，而19名受试者（7名男性，12名女性，平均年龄30 +/-10岁）被诊断为非磨牙者。临床和EMG/ECG SB诊断之间的相关性较低（phi值= 0.250），两种方法之间的一致性为62.2%（28/45例受试者）（kappa = 0.248）。假设仪器EMG/ECG诊断作为本研究中明确SB诊断的参考标准，则所有临床体征/症状的假阳性和假阴性率均不可接受。总之，临床评估的结果与使用便携式EMG/ECG记录仪进行的SB诊断无关。
The aim of this study was to compare clinical sleep bruxism (SB) diagnosis with an instrumental diagnosis obtained with a device providing electromyography/electrocardiography (EMG/ECG) recordings. Forty-five (N = 45) subjects (19 males and 26 females, mean age 28 +/- 11 years) were selected among patients referring to the Gnathology Unit of the Dental School of the University of Torino. An expert clinician assessed the presence of SB based on the presence of one or more signs/symptoms (i.e. transient jaw muscle pain in the morning, muscle fatigue at awakening, presence of tooth wear, masseter hypertrophy). Furthermore, all participants underwent an instrumental recording at home with a portable device (Bruxoff (R); OT Bioelettronica, Torino, Italy) allowing a simultaneous recording of EMG signals from both the masseter muscles as well as heart frequency. Statistical procedures were performed with the software Statistical Package for the Social Science v. 20.0 (SPSS 20.0 (R); IBM, Milan, Italy). Based on the EMG/ECG analysis, 26 subjects (11 males, 15 females, mean age 28 +/- 10 years) were diagnosed as sleep bruxers, whilst 19 subjects (7 males, 12 females, mean age 30 +/- 10 years) were diagnosed as non-bruxers. The correlation between the clinical and EMG/ECG SB diagnoses was low (phi value = 0.250), with a 62.2% agreement (28/45 subjects) between the two approaches (kappa = 0.248). Assuming instrumental EMG/ECG diagnosis as the standard of reference for definite SB diagnosis in this investigation, the false-positive and false-negative rates were unacceptable for all clinical signs/symptoms. In conclusion, findings from clinical assessment are not related with SB diagnosis performed with a portable EMG/ECG recorder.
