Oral health status and oral health-related quality of life: a cross-sectional study of clients in an Australian opioid treatment program.

Background Individuals with opioid dependence often experience poor oral health, including dental decay, periodontal disease and mucosal infection, frequently exacerbated by factors such as smoking, alcohol consumption, inadequate oral hygiene and low utilisation of oral health services. This study aimed to assess oral health status and oral health-related quality of life (OHRQoL) among opioid-dependent individuals and explore their potential associations. Methods Participants enrolled in an opioid treatment program (OTP) at three Australian urban clinics were assessed using the validated Oral Health Assessment Tool (OHAT) and Oral Health Impact Profile (OHIP-14).
