In this pilot study, the general pain perception and the dental pulp sensibility of probable sleep bruxism (SB) subjects were compared with that of non-SB subjects. The cold pressor test (CPT), electric pulp test (EPT), and thermal pulp test with CO snow were executed by one trained dentist (blind to SB diagnosis). A one-factorial multivariate analysis of variance (MANOVA) with SB diagnosis as independent variable and standardized measures regarding pain perception and evaluation was performed. One-hundred-and-five participants (53 SB and 52 non-SB subjects) were included. The one-factorial MANOVA revealed a significant difference between SB and non-SB subjects (p = 0.01) concerning pain perception variables. Post-hoc univariate analyses of variance (ANOVA) showed statistically significant lower general pain tolerance (p = 0.02), higher general subjective sensibility of the teeth (p < 0.01), and a statistical trend for higher subjective dental pain intensity (p = 0.07) in SB subjects. In most of the standardized variables, probable SB subjects seem to react and feel similar to non-SB subjects. However, as probable SB subjects subjectively perceive their teeth to be more sensitive and tend to rate their subjective dental pain intensity more intensely after CO testing, data might point to a somatosensory amplification.
在这项初步研究中，比较了可能的睡眠磨牙症（SB）患者和非 SB 患者的一般疼痛感知和牙髓敏感性。由一名受过训练的牙医（对 SB 诊断不知情）进行冷加压试验（CPT）、电牙髓测试（EPT）和 CO 雪的热牙髓测试。采用单因素多元方差分析（MANOVA），以 SB 诊断为自变量，以疼痛感知和评估的标准化指标为因变量进行分析。共纳入 105 名参与者（53 名 SB 患者和 52 名非 SB 患者）。单因素 MANOVA 显示 SB 和非 SB 患者在疼痛感知变量方面存在显著差异（p=0.01）。事后单因素方差分析（ANOVA）显示，SB 患者的一般疼痛耐受力显著降低（p=0.02），牙齿一般主观敏感性更高（p<0.01），主观牙齿疼痛强度也有统计学趋势（p=0.07）。在大多数标准化变量中，可能的 SB 患者的反应和感觉似乎与非 SB 患者相似。然而，由于可能的 SB 患者主观上认为他们的牙齿更敏感，并且在 CO 测试后往往会更强烈地评定他们的主观牙齿疼痛强度，这些数据可能表明存在躯体感觉放大。
