To investigate the influence of patient neuroticism on oral health-related quality of life (OHRQoL) in complete denture wearers.
There are some indicators of complete denture prognosis. The relationship between personality traits, mainly neuroticism and OHRQoL in complete denture wearers remains unclear.
A total of 199 edentulous patients participated in this study. Neuroticism was investigated using the Japanese version of the modified short form of the Eysenck Personality Questionnaire (MS-EPQ). OHRQoL was measured according to the Japanese version of the Oral Health Impact Profile for edentulous subjects (OHIP-EDENT-J). Structural equation modelling was used to evaluate the relationship between neuroticism and subscales of the OHIP-EDENT-J.
The High and Low neuroticism groups fit the same model for the 5 subscales of the OHIP-EDENT-J-functional limitation, pain, disability, discomfort and handicap-with different path coefficients. The path from functional limitation to handicap via pain, disability and discomfort was the same as previously reported. However, path coefficients for pain to disability differed significantly between the 2 neuroticism groups. The High neuroticism group had higher estimated path coefficients for Pain compared with those for other subscales than did the Low neuroticism group. This finding indicates that the participants who are high in neuroticism felt pain more strongly, and their disability increased.
Neuroticism may influence OHRQoL in complete denture wearers because of patients' perception of pain.
探讨患者神经质对全口义齿佩戴者口腔健康相关生活质量（OHRQoL）的影响。
全口义齿预后有一些指标。人格特质（主要是神经质）与全口义齿佩戴者的OHRQoL之间的关系仍不清楚。
共有199名无牙颌患者参与本研究。使用日本版的艾森克人格问卷简式修订版（MS-EPQ）调查神经质。根据日本版的无牙颌受试者口腔健康影响程度量表（OHIP-EDENT-J）测量OHRQoL。采用结构方程模型评估神经质与OHIP-EDENT-J各分量表之间的关系。
高神经质组和低神经质组对OHIP-EDENT-J的5个分量表（功能受限、疼痛、残疾、不适和障碍）拟合相同模型，但路径系数不同。从功能受限经疼痛、残疾和不适到障碍的路径与先前报道相同。然而，疼痛到残疾的路径系数在两组神经质组之间存在显著差异。与低神经质组相比，高神经质组疼痛的估计路径系数高于其他分量表。这一发现表明，神经质得分高的参与者对疼痛的感受更强烈，残疾程度增加。
神经质可能因患者对疼痛的感知而影响全口义齿佩戴者的OHRQoL。
