“…According to this model, we propose that OHRQoL is affected by personal characteristics (educational level), environmental factors (annual family income), physical (chronic disease and oral health status), social, and psychosocial functioning (anxiety and BQD). Of the few studies that have explored this topic, most have researched populations in Western Asia [ 10 , 11 ], northern India [ 24 ], South Asia [ 12 ], older adults [ 18 , 19 , 21 ], and patients with diabetes [ 23 ]. Therefore, the aims of this study are, in BQ users receiving oral mucosal screening, (1) to investigate the levels of oral health, anxiety, BQD, and OHRQoL; and (2) to examine the factors (e.g., educational level, annual family income, chronic disease, oral health status, anxiety, and BQD) associated with OHRQoL.…”
