Oral health is crucial for overall well-being, yet individuals with psychiatric disorders often experience severe dental issues exacerbated by medication-induced xerostomia and avoidant behaviours towards oral care. Socioeconomic factors and gender differences further impact oral health, with disadvantaged groups facing greater barriers to dental care. Despite the recognized link between mental and oral health, reserach on effective oral health interventions in inpatient settings remains limited. To address this gap, Windsor Regional Hospital implemented an Oral Education program in December 2022 within its acute care mental health unit, aiming to provide tailored interventions directly to patients. This project will evaluate the program's impact on patients' oral health knowledge, behaviours, and quality of life over time, considering variations across different mental health conditions and socio-demographic factors. Anticipated results include a clearer understanding of the program's effectiveness, identification of potential enhancements, and development of informed policy recommendations to better integrate oral health into patient care.
