To our knowledge, the association between personality traits and oral health impacts on daily activities among patients under periodontal maintenance was not previously evaluated. The present study aims to determine the oral health impacts among regular- and erratic-complier patients and their correlations with personality traits by means of the oral impacts on daily performance (OIDP) and the neuroticism extraversion openness five-factor inventory (NEO FFI-R) instruments.
A total of 58 regular and 58 erratic compliers matched by sex, diabetes, and smoking were recruited from a cohort of 238 participants under periodontal maintenance. Periodontal examinations and questionnaire applications were performed in recalls during a 3-year interval. The influence of variables of interest on the OIDP was evaluated through univariate and multivariate linear regression analyses.
The periodontal status of regular compliers was significantly better than that of erratic compliers. Erratic compliers presented higher OIDP scores (36.34 ± 6.64) compared to regular compliers (30.45 ± 7.72). Higher scores of neuroticism and conscientiousness (R(2) = 68%; P <0.001) were associated with higher OIDP scores among regular compliers, whereas among erratic compliers, lower scores of neuroticism, higher openness, and extraversion (R(2) = 77%; P = 0.001) were associated with higher OIDP scores.
Personality traits, mainly neuroticism, showed significant influences on OIDP among patients under periodontal maintenance.
据我们所知，人格特质与牙周维护患者日常活动中口腔健康的关系尚未得到评估。本研究旨在通过口腔影响日常生活量表（OIDP）和神经质-外向性-开放性五因素人格量表（NEO FFI-R）评估定期和不定期依从者的口腔健康影响及其与人格特质的相关性。
从 238 名牙周维护队列中，按性别、糖尿病和吸烟情况匹配了 58 名定期和 58 名不定期依从者。在 3 年的随访期间，进行牙周检查和问卷调查。通过单变量和多变量线性回归分析评估感兴趣变量对 OIDP 的影响。
定期依从者的牙周状况明显优于不定期依从者。不定期依从者的 OIDP 评分（36.34±6.64）高于定期依从者（30.45±7.72）。神经质和尽责性评分较高（R²=68%；P<0.001）与定期依从者的 OIDP 评分较高相关，而在不定期依从者中，神经质评分较低、开放性和外向性评分较高（R²=77%；P=0.001）与 OIDP 评分较高相关。
人格特质，主要是神经质，对牙周维护患者的 OIDP 有显著影响。
