Prevalence of oral mucosal disorders in institutionalized and non-institutionalized psychiatric patients: a study from AVBR Hospital in central India.

Dental treatment is reported to be the greatest unattended health need of people with a disability. The aim of the present study was therefore to quantify the prevalence of oral diseases with a psychosomatic component (recurrent aphthous stomatitis, burning mouth syndrome, and oral lichen planus) in psychiatric patients and to screen these patients for any other oral disorders, so that better care could be provided. In this cross-sectional, single-assessment study, 150 psychiatric patients were evaluated for presence of oral disorders. They were screened based on their socio-demographic profiles, clinical profile, and standardized psychiatric scales. The prevalence of recurrent aphthous stomatitis (RAS), burning mouth syndrome (BMS), and oral lichen planus (OLP) was 19.33%(29 patients), 20.66% (31 patients) and 5.33% (8 patients), respectively, amongst all psychiatric patients. The prevalence of burning mouth syndrome was much higher in patients taking psychiatric medications (25%) than in drug-naïve patients. On screening for other oral disorders, 35.33% of psychiatric patients had at least one other such disorder. We concluded that this patient group experiences a considerable burden of occult oral disorders necessitating thorough oral care. We also described the possible causes of the higher prevalence of oral disorders in psychiatric patients.
