Aim: This study aims to detect the prevalence of oral manifestations in patients with psychiatric disorders on psychotropic medications. Materials and methods: A total of 46 patients above the age of 18 years who have been diagnosed with psychiatric illness and under psychotropic medications were included in this study. Thorough case history and oral findings were recorded. Patients with already existing systemic illness and other oral manifestations were excluded from this study. Results: Out of 46 patients, 34 patients presented with oral manifestations such as xerostomia, sialorrhea, geographic tongue, candidiasis, and burning mouth syndrome, secondary to the use of psychotropic medications. The oral manifestations were significantly higher in the patients under antipsychotics (80.0%), selective serotonin reuptake inhibitor (66.7%), antiepileptics (55.6%), antidepressants (44.4%), benzodiazepine (44.4%), and tricyclic antidepressants (13.7%). Conclusion: The commonly used psychotropic medications to treat patients with psychiatric illnesses such as selective serotonin reuptake inhibitor, tricyclic antidepressants, antidepressants, and benzodiazepines exhibited several oral manifestations. However, long-term use of these medications seems to cause oral changes. Clinical significance: Awareness among psychiatrists about oral changes associated with the use of psychotropic medication will assist them to make necessary modifications in the prescriptions. Dental practitioners will be able to recognize these changes early in the course of the condition and provide appropriate treatment.
