The Dentine Hypersensitivity Experience Questionnaire (DHEQ) is a valid and reliable instrument for oral health-related quality of life (OHRQoL) studies. This study aimed to assess the Turkish version of the DHEQ and determine the effects of degree of DH, sex, and age on OHRQoL.
The study participants were 251 DH patients (age 18-78 years; 68.5% female) who completed the Turkish version of the DHEQ. The reliability of the instrument was assessed in terms of internal consistency, using item-total correlations and Cronbach's alpha and test-retest reliability using intra-class correlation coefficients (ICCs) among 51 patients who repeated the DHEQ following a 2-week interval. Construct validity was determined based on exploratory factor analysis (EFA). Convergent validity was tested through correlating DHEQ total and subscale scores with the global rating of oral health and effect on life overall. Discriminative validity was tested by comparing the total and subscale scores against the degree of sensitivity.
Patients with more severe hypersensitivity showed higher DHEQ scores and greater OHRQoL impairment. Female and older (⟩40 years) patients had significantly greater OHRQoL impairment. Cronbach's alpha exceeded 0.70, indicating good internal consistency reliability. The ICC values measured were ⟩0.60 for the overall scale and each subscale of the DHEQ, signifying good to excellent test-retest reliability.
The results suggested that the Turkish version of the DHEQ is appropriate for assessing the OHRQoL among people with dentine hypersensitivity.
牙本质过敏体验问卷（DHEQ）是用于口腔健康相关生活质量（OHRQoL）研究的有效且可靠的工具。本研究旨在评估DHEQ的土耳其语版本，并确定牙本质过敏程度、性别和年龄对OHRQoL的影响。
研究参与者为251名完成DHEQ土耳其语版本的牙本质过敏患者（年龄18 - 78岁；68.5%为女性）。通过项目总分相关性和Cronbach's α评估该工具的内部一致性可靠性，并在51名间隔2周后重复填写DHEQ的患者中使用组内相关系数（ICC）评估重测可靠性。基于探索性因子分析（EFA）确定结构效度。通过将DHEQ总分和子量表得分与口腔健康总体评分及对整体生活的影响进行相关性分析来测试收敛效度。通过比较总分和子量表得分与敏感程度来测试区分效度。
过敏程度更严重的患者DHEQ得分更高，OHRQoL受损更严重。女性和年龄较大（＞40岁）的患者OHRQoL受损更显著。Cronbach's α超过0.70，表明内部一致性可靠性良好。DHEQ总体量表及各子量表的ICC值均＞0.60，表明重测可靠性良好至优秀。
结果表明，DHEQ的土耳其语版本适用于评估牙本质过敏患者的OHRQoL。
