Assessment of the psychological impact of dental aesthetics among undergraduate university students in Iraq.

Aim: 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.

Methods: 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 P value of less than 0.05 was considered statistically significant. Reliability analysis was conducted using Cronbach's alpha.

Result: 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).

Conclusions: 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.
