This study aimed to assess Iraqi university students' oral health-related quality of life (OHRQoL) according to sociodemographic variables and compare dental and non-dental students.
A cross-sectional study was carried out for students in multiple Iraqi universities from June 15, 2022, to July 15, 2022. A total of 771 individuals participated in the study using an online questionnaire. A pre-tested and validated Arabic version of the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) was adopted as an evaluation tool. A value of less than 0.05 was considered statistically significant. Reliability analysis was conducted using Cronbach's alpha.
Cronbach's alpha score for the overall scales was 0.942, indicating excellent internal consistency. There were 69.8% (n = 538) dental students in the total sample. A significant difference was found between dental and non-dental students in the total PIDAQ scores and other subscale domains (P < 0.05). Statistically significant differences in means were also noted in the residency (P = 0.005) and household income of students (P = 0.000).
This study shows the reliability of the PIDAQ scale for assessing the psychological impact of dental aesthetics on undergraduate Iraqis. It was found that the perception of OHRQoL varies between dental and non-dental university students, and according to socioeconomic status and residency.
本研究旨在根据社会人口统计学变量评估伊拉克大学生的口腔健康相关生活质量（OHRQoL），并比较牙科专业和非牙科专业的学生。
于2022年6月15日至2022年7月15日对伊拉克多所大学的学生进行了一项横断面研究。共有771人通过在线问卷参与了该研究。采用经过预测试和验证的阿拉伯语版牙科美学心理社会影响问卷（PIDAQ）作为评估工具。P值小于0.05被认为具有统计学意义。使用Cronbach's alpha进行信度分析。
总体量表的Cronbach's alpha得分为0.942，表明具有出色的内部一致性。总样本中有69.8%（n = 538）为牙科专业学生。在PIDAQ总分及其他子量表领域，牙科专业和非牙科专业学生之间存在显著差异（P < 0.05）。在学生的居住地（P = 0.005）和家庭收入方面（P = 0.000）也发现了均值的统计学显著差异。
本研究表明PIDAQ量表在评估牙科美学对伊拉克本科生心理影响方面具有可靠性。研究发现，牙科专业和非牙科专业的大学生对OHRQoL的认知存在差异，且因社会经济地位和居住地而异。
