Body dysmorphia in dentistry and prosthodontics: A practice based study.

The prevalence of Body Dysmorphic Disorder (BDD) and dysmorphic concern in dentistry and prosthodontics have not been properly assessed, yet the mouth and the teeth are amongst the top preoccupation for these individuals.

OBJECTIVES: To evaluate the prevalence of dysmorphic symptoms and BDD using validated tools in patients presenting to general and specialist prosthodontic practice.

METHODS: Patients were recruited by two prosthodontics practices and three general dentist practices. Patients were given a Dysmorphic Concern Questionnaire (DCQ) integrated into a medical history form. Treating clinicians also completed a Baseline Rating Form assessing the patients´ reason for presentation. Two DCQ score cut-offs were used (9 and 12).

RESULTS: Two hundred and thirteen patients were recruited, the majority of patients showed DCQ scores below 9 (84%). The prevalence of BDD was 7% (cut-off ≥ 9) or 4% (cut-off ≥12). Women were more likely to present with high DCQ scores as well as people with a history of mental health problems. The cosmetic practice, the implant clinic, and the prosthodontic practice received a higher proportion of patients with high DCQ scores when compared with the general family practice. The type of procedure was not related to DCQ scores. The defect severity assessment and whether this was amenable to correction was moderately correlated with DCQ scores.

CONCLUSIONS: The DCQ seems to be a suitable tool to be used by dentists as part of history taking and patient examination due to its brevity, simplicity and the good sensitivity/specificity reported in the literature.

CLINICAL SIGNIFICANCE: Identifying patients with dysmorphia is important before irreversible treatment is carried out due to high levels of dissatisfaction, poor patient centred outcomes and the question of whether these individuals have the capacity to consent.
