Exploring Oral Health Inequities, Oral Functioning, and Quality of Life in Substance Use Rehabilitation Centers

BACKGROUND: Substance use disorders negatively impact oral health, but there is limited data on their relationship with oral function, overall health, and quality of life in affected individuals. AIMS: To assess the oral health-related quality of life (OHRQoL) and quality of life among substance users and explore the influence of oral health status, function, and dental care access on these outcomes. MATERIALS AND METHODS: This cross-sectional study collected data from 42 participants from a rehabilitation center via a structured online questionnaire using validated and reliable tools that assessed oral hygiene, smoking, alcohol use, oral and general health, quality of life, OHRQoL, and access to dental services. RESULTS: The 42 participants exhibited moderate impairment in oral health-related quality of life. Missing teeth, financial barriers, and poor access to dental care were associated with worse oral health outcomes (p < 0.05). Oral functioning strongly influenced both OHRQoL and overall health (p < 0.05). CONCLUSION: There is a critical need for integrated, patient-centered oral healthcare programs within addiction rehabilitation settings to enhance treatment effectiveness and quality of life for this underserved population.
