Studies investigating the relationship between personality traits and quality of life related to the types of dental prostheses are scarce. The aim of the present study was to assess personality traits and their impact on quality of life for individuals treated with either conventional mandibular dentures (CMD) or implant-supported overdentures. Fifty patients with CMD and 50 patients with implant-supported mandibular overdentures (IMOD) were recruited. Individuals were examined; clinical and demographic data of interest were collected. All participants agreed to answer two questionnaires: the Oral Health Impact Profile (OHIP-14), which assessed quality of life related to oral health, and the Neuroticism Extraversion Openness Five-Factors Inventory (NEO FFI-R), which evaluated five personality domains. The influence of variables of interest on oral health-related quality of life was tested by univariate analysis and multiple linear regression. Patients with CMD reported higher levels of impact on quality of life (OHIP-14=10·30 ± 5·88) when compared to patients with IMOD (OHIP-14=6·52 ± 5·91; P=0·002). Multivariate predictive regression model for quality of life included neuroticism, conscientiousness and gender for the conventional mandibular denture group (P<0·05; R(2)=36·59%), whereas neuroticism, openness and schooling (P<0·05; R(2)=21·09%) were included in the implant-supported mandibular denture group model. Patients with IMOD had less impact on quality of life than patients with CMD. Personality traits, mainly neuroticism, had a significant influence on oral health-related quality of life linked to a chosen modality of prosthetic therapy.
研究人格特质与与义齿类型相关的生活质量之间的关系的研究很少。本研究旨在评估人格特质及其对接受传统下颌义齿（CMD）或种植体支持覆盖义齿（IMOD）治疗的个体生活质量的影响。招募了 50 名接受 CMD 治疗的患者和 50 名接受种植体支持下颌覆盖义齿（IMOD）治疗的患者。对患者进行检查，收集了感兴趣的临床和人口统计学数据。所有参与者均同意回答两个问卷：口腔健康影响量表（OHIP-14），评估与口腔健康相关的生活质量；神经质-外向性-开放性五因素量表（NEO FFI-R），评估五个人格领域。通过单变量分析和多元线性回归测试了感兴趣变量对口腔健康相关生活质量的影响。与 IMOD 组（OHIP-14=6.52±5.91；P=0.002）相比，CMD 组患者报告对生活质量的影响更高（OHIP-14=10.30±5.88）。常规下颌义齿组生活质量的多元预测回归模型包括神经质、尽责性和性别（P<0.05；R(2)=36.59%），而 IMOD 组模型包括神经质、开放性和教育程度（P<0.05；R(2)=21.09%）。与 CMD 组相比，接受 IMOD 治疗的患者对生活质量的影响较小。人格特质，主要是神经质，对与选择的修复治疗方式相关的口腔健康相关生活质量有显著影响。
