This study sought to assess the impact of posterior cross-bite on OHRQoL in young people aged 15-25 and to determine whether the impact on higher domains of Oral Health Impact Profile-14 (physical disability, psychological disability, social disability and handicap) is a direct function of the cross-bite or mediated through the lower domains of OHIP-14 (functional limitation, pain and discomfort).
One hundred and forty-five young adults [72 cross-bite cases and 73 controls] aged 15-25 years, attending orthodontic clinics at the Faculty of Dentistry, Universiti Teknologi MARA participated in this study. Participants completed the OHIP-14 and had a clinical examination for cross-bite. Data analyses included descriptive statistics, t-test and bivariate and multivariate regression modelling.
There was no significant difference between the case and control groups in gender, age and education level. The mean scores (±SD) for OHIP-14 total and all domains were significantly higher in cross-bite patients as compared to controls. The bivariate and multivariate regression analyses showed functional limitation was significantly associated with all the higher domains in all four models, whereas pain was only significantly associated with the psychological domain and discomfort was only significantly associated with the physical disability domain.
The possession of a posterior cross bite has a significant association with OHRQoL especially on the functional limitation and psychological disability domains, among 15-25 years old young people. The relationship of cross-bite and lower domains of OHIP-14 with higher domains of OHIP-14 was in agreement with the relationships proposed by Locker's conceptual model of oral health.
Patients with a cross bite were more limited in their oral functions and experienced greater psychological discomfort than did controls. It is possible that part of patients' rationale for seeking treatment would be to alleviate such impacts on their oral health related quality of life.
本研究旨在评估后牙反牙合对15至25岁年轻人口腔健康相关生活质量（OHRQoL）的影响，并确定其对口腔健康影响程度量表-14（OHIP-14）较高领域（身体残疾、心理残疾、社会残疾和障碍）的影响是反牙合的直接作用，还是通过OHIP-14较低领域（功能受限、疼痛和不适）介导的。
145名年龄在15至25岁之间的年轻成年人[72例反牙合病例和73名对照]参与了本研究，他们在马来西亚理科大学牙科学院正畸诊所就诊。参与者完成了OHIP-14问卷，并接受了反牙合的临床检查。数据分析包括描述性统计、t检验以及双变量和多变量回归建模。
病例组和对照组在性别、年龄和教育水平上无显著差异。与对照组相比，反牙合患者的OHIP-14总分及所有领域的平均得分（±标准差）显著更高。双变量和多变量回归分析表明，在所有四个模型中，功能受限与所有较高领域均显著相关，而疼痛仅与心理领域显著相关，不适仅与身体残疾领域显著相关。
后牙反牙合与OHRQoL显著相关，尤其是在15至25岁的年轻人中，对功能受限和心理残疾领域影响显著。反牙合以及OHIP-14较低领域与OHIP-14较高领域的关系与Locker口腔健康概念模型所提出的关系一致。
与对照组相比，反牙合患者的口腔功能受限更明显，心理不适更严重。患者寻求治疗的部分原因可能是为了减轻对其口腔健康相关生活质量的此类影响。
