“…OHL has been defined as “the degree to which individuals have the capacity to obtain, process, and understand the basic health information and services needed to make appropriate oral health decisions” ( American Dental Association, 2006a , American Dental Association, 2006b ). Studies have indicated that poor OHL is a risk factor for oral diseases ( Batista et al, 2018 , Neves et al, 2023 ). In the last decade, OHL has thus received considerable attention in the dental literature ( Baskaradoss, 2018 ) and is deemed an important concept in dental research as well as dental practice ( Bennett et al, 2009 , Horowitz and Kleinman, 2008 , Jackson and Eckert, 2008 , Jones et al, 2007 ).…”
