Burning mouth syndrome (BMS) is a chronic disease in which patients feel a burning sensation and pain in the oral cavity. Although personality traits have been suggested to influence the development and course of BMS, they have not yet been examined in detail. We therefore investigated the personality traits of BMS patients.
Sample consisted of 65 BMS patients presenting to the Aichi-Gakuin Dental School Hospital between May 2005 and April 2009. They were also diagnosed as having pain disorder by a psychiatrist. The control group consisted of 116 healthy subjects. The Temperament and Character Inventory (TCI) was used to evaluate personality traits, while the Beck Depression Inventory (BDI) was used to evaluate the depression rate in both groups.
In TCI, we found that, in comparison to the control group, the novelty seeking score was significantly lower (p = 0.009), the harm avoidance score was significantly higher (p < 0.001), and the self-directedness score was significantly lower (p = 0.039) in the BMS group. To remove the influence of depression, we performed an analysis of covariance of each TCI item using the BDI score as a covariate. No significant differences were observed in harm avoidance or self-directedness, whereas the differences noted in novelty seeking were significant (p = 0.008).
The novelty seeking score was low in BMS patients in comparison to the control group. They also had high harm avoidance and low self-directedness tendencies, but these were attributed to the influence of depression.
灼口综合征（BMS）是一种慢性疾病，患者会感到口腔内有灼烧感和疼痛。尽管有人提出人格特质会影响灼口综合征的发生和发展过程，但尚未进行详细研究。因此，我们调查了灼口综合征患者的人格特质。
样本包括2005年5月至2009年4月期间到爱知学院齿科学院医院就诊的65例灼口综合征患者。他们还被精神科医生诊断为患有疼痛障碍。对照组由116名健康受试者组成。使用气质和性格量表（TCI）评估人格特质，同时使用贝克抑郁量表（BDI）评估两组的抑郁率。
在TCI中，我们发现，与对照组相比，灼口综合征组的寻求新奇得分显著降低（p = 0.009），回避伤害得分显著升高（p < 0.001），自我导向得分显著降低（p = 0.039）。为消除抑郁的影响，我们以BDI得分作为协变量对每个TCI项目进行协方差分析。在回避伤害或自我导向方面未观察到显著差异，而在寻求新奇方面的差异显著（p = 0.008）。
与对照组相比，灼口综合征患者的寻求新奇得分较低。他们还具有高回避伤害和低自我导向倾向，但这些归因于抑郁的影响。
