Body Dysmorphic Disorder And Oral Health-Related Quality Of Life
Objectives: The objectives of this study were to identify associations between body dysmorphic disorders (BDD) and demographic factors or the severity of the maxillomandibular discrepancy (MMD) in patients undergoing orthognathic surgery, and correlations between BDD and oral health-related quality of life (OHRQoL).
Methods: A prospective study was conducted with ethics approval and written patient consent. Patients aged 16 to 60 years planned for orthognathic surgery from August 2022 to June 2023 were included. Patients with a history of maxillofacial trauma, pathology or surgery or craniofacial syndromes were excluded. Demographic data of their age, gender and history of psychiatric disorders was collected. Their skeletal relationship and MMD severity (using overjet and overbite) was recorded. The patients completed two screening questionnaires for BDD, the Body Dysmorphic Disorder Questionnaire (BDDQ) and Appearance Anxiety Inventory (AAI), and one questionnaire for assessment of their OHRQoL, the Oral Health Impact Profile-14 (OHIP-14). Their BDDQ and AAI scores were analysed for associations with their demographic data, skeletal relationship and MMD severity. Their scores were also analysed for correlations with their overall OHIP-14 score, and their scores in each of the OHIP-14’s seven domains.
Results: 41 patients were included. AAI scores significantly correlated with BDDQ scores (p=0.005). Age, gender, skeletal relationship and degree of MMD were not associated with BDDQ or AAI scores. Higher AAI scores correlated with higher OHIP-14 scores, both overall and in all domains (p=<0.001). Higher BDDQ scores correlated with higher overall OHIP-14 scores (p=0.005), and in the domains of function (p=0.023), physical pain (p=0.022), psychological discomfort (p=0.002) and physical disability (p=0.034).
Conclusions: BDD is not associated with age, gender, skeletal relationship or severity of MMD. BDD, however, does correlate with poorer overall OHRQoL and physical and psychological function. As orthognathic surgery may not treat BDD, clinicians should implement routine screenings to identify at-risk patients.
