Background: Dentofacial deformity (DFD) is a disease in which the maxillary complex markedly diverges from normal proportions. The incidence of DFD is approximately 20% worldwide, and patients with DFDs are at increased risk for depression. Attention should be given to depression in patients with DFDs. However, factors affecting depression in patients with DFDs remain unclear. Previous studies have suggested that the type of DFD and esthetic expectations may influence patient depression, but few studies have clarified the effects of the type of DFD and esthetic expectations on patient depression.Methods: A total of 471 patients with DFDs were enrolled. The diagnosis of DFD was made by two maxillofacial surgeons according to the Angle's classification. The visual analog assessment scale of esthetic expectations was used to assess patients’ esthetic expectations. The 9-item Patient Health Questionnaire depression module was utilized to explore patient depression. SPSS 26.0 was used to analyze the data in this study.Results: Compared with DFD patients who had a master’s degree or above, those who had a high school education were more prone to depression (OR=3.848, 95% CI: 1.546-9.574). Compared with Class II DFDs, Class III DFDs were associated with a greater risk of depression (OR=1.458, 95% CI: 1.007–2.078). Compared with those who had extremely low esthetic expectations, those who had extremely high esthetic expectations (OR: 2.25, 95% CI: 1.053–4.086) were more prone to depression.Conclusions: Patients who had a high school education, were diagnosed with Class III DFDs, and had higher esthetic expectations had a greater risk of depression. The above populations may need more psychological support.
