The aim of this study was to investigate the oral health-related quality of life (OHRQoL) among subjects with typical, atypically positive, and atypically negative personality trait scores within the five basic dimensions of personality (neuroticism, extroversion, openness, agreeableness, and conscientiousness).
A total of 235 subjects not seeking dental treatment were recruited from the families and acquaintances of dental students from the University of Salamanca. The 14-item Oral Health Impact Profile (OHIP-14) was used to capture the impact on their OHRQoL. The Neouroticism-Extroversion-Openness Personality Inventory Revised was applied to assess personality profiles. People were classified as having negatively atypical, typical, or positively atypical (PAP) personality, depending on whether the sum of the Z scores was < -1, between -1 and 1, or > 1, respectively. Pearson correlation, analysis of variance, and logistic regression test were used for the statistical analyses.
The sample was comprised of highly educated adults (aged 18-80 years) with good oral health habits. PAP subjects suffered significantly more in the dimension of psychologic discomfort (0.6 ± 0.7) than did their counterparts (0.3 ± 0.6), but the global impact in OHRQoL was comparable. Personality was weakly correlated with OHIP-14. The perception of dental treatment needs was found to be the major predictor of the impact on OHRQoL, but the number of negatively atypical deviated personality traits and the agreeableness raw score also had an effect.
The risk of perceiving an impact on OHRQoL is significantly higher in individuals perceiving treatment needs and increases proportionally to the number of negatively atypical personality traits.
本研究旨在调查在人格五个基本维度（神经质、外向性、开放性、宜人性和尽责性）中具有典型、非典型阳性和非典型阴性人格特质分数的受试者的口腔健康相关生活质量（OHRQoL）。
从萨拉曼卡大学牙科学生的家人和熟人中招募了235名未寻求牙科治疗的受试者。使用14项口腔健康影响量表（OHIP - 14）来评估对他们OHRQoL的影响。应用修订后的神经质 - 外向性 - 开放性人格量表来评估人格特征。根据Z分数总和分别< - 1、在 - 1和1之间或> 1，将人们分类为具有负非典型、典型或正非典型（PAP）人格。采用Pearson相关性分析、方差分析和逻辑回归检验进行统计分析。
样本由具有良好口腔健康习惯的高学历成年人（年龄在18 - 80岁之间）组成。PAP受试者在心理不适维度上的痛苦程度（0.6±0.7）明显高于其对应人群（0.3±0.6），但对OHRQoL的总体影响相当。人格与OHIP - 14呈弱相关。发现对牙科治疗需求的认知是影响OHRQoL的主要预测因素，但负非典型偏离人格特质的数量和宜人性原始分数也有影响。
感知到治疗需求的个体中，认为对OHRQoL有影响的风险显著更高，且与负非典型人格特质的数量成比例增加。
