Abstract：
BACKGROUND We used the 14-item Oral Health Impact Profile-14 (OHIP-14) questionnaire to evaluate the association between sociodemographic variables and oral health-related quality of life in 241 wearers of removable partial or complete dentures attending a single center in Yemen. MATERIAL AND METHODS A total of 241 partial dentures (PD) and complete dentures (CD) wearers were enrolled from the Department of Prosthodontics at the Faculty of Dentistry, Sana\'a University, and the University of Science and Technology. Data were collected before the commencement of denture wearing and after 3-6 months of denture use. The questionnaire consisted of sociodemographic information and denture type, and another for the OHIP to assess oral health-related quality of life (OHRQoL), oral health impact profile scale comprises 7 subscales, each evaluating different aspects of oral health and functionality. Descriptive statistics were calculated for participants. Independent t tests were performed to compare different patient groups, focusing on PD and CD wearers. Paired-sample t tests were used to examine changes within patient groups before and after removable denture use. RESULTS Among all participants, 67.6% were male, wearers of CDs were 74.6% male, PDs were 58.3%, and was consistent for CD (71.0%) and PD (72.8%) wearers. The wearing prostheses significantly impacted the OHRQoL of patients using both PDs and CDs (P<0.01). Among CD wearers, 4 of these subscales (3-6) were statistically significant, but the handicaps subscale showed evident reductions in physical pain after treatment among PD wearers. CONCLUSIONS Wearing dentures positively affects the OHRQoL of patients, influencing various aspects of their health, including functional, physical, psychological, and social well-being.
摘要：
背景技术我们使用14项口腔健康影响概况-14(OHIP-14)问卷评估了来自也门一个中心的241名可移动部分或完整义齿佩戴者的社会人口统计学变量与口腔健康相关生活质量之间的关系。材料与方法从牙科学院口腔修复学系共招募了241个局部义齿（PD）和全口义齿（CD）佩戴者，萨那大学，和科技大学。在开始佩戴义齿之前和使用义齿3-6个月后收集数据。问卷包括社会人口统计信息和义齿类型，另一个是OHIP评估口腔健康相关生活质量（OHRQoL），口腔健康影响量表包括7个分量表，每个评估口腔健康和功能的不同方面。对参与者进行描述性统计。进行独立t检验以比较不同的患者组，专注于PD和CD佩戴者。配对样本t检验用于检查使用可摘义齿前后患者组内的变化。结果在所有参与者中，67.6%为男性，CD的佩戴者是74.6%的男性，PD为58.3％，CD（71.0%）和PD（72.8%）佩戴者一致。佩戴假体对PD和CD患者的OHRQoL有显著影响(P<0.01)。在CD佩戴者中，这些分量表（3-6）中有4个具有统计学意义，但是障碍分量表显示，PD穿着者治疗后的身体疼痛明显减轻。结论佩戴假牙对患者的OHRQoL有积极影响，影响他们健康的各个方面，包括功能，物理，心理,和社会福祉。
