“…The factors that impact self-reported oral health are not well understood, but it has been suggested that oral diseases have a negative impact on self-reported oral health, and that this impact is worse at younger ages ( Slade and Sanders, 2011 ). Several researchers evaluated OHRQoL in young adult subjects in Australia ( Brennan and Spencer, 2009 ), Tanzania ( Masalu and Astrøm, 2002 ), Japan ( Yamane-Takeuchi et al, 2016 ), Malaysia ( Masood et al, 2013 ), Sweden ( Oscarson et al, 2007 ), Korea ( Choi et al, 2015 ), and Saudi Arabia ( Bahammam and Fareed, 2019 ). To summarize, OHRQoL in young adults was affected by education ( Masalu and Astrøm, 2002 , Masood et al, 2013 ), negative life experience ( Brennan and Spencer, 2009 ), pain ( Yamane-Takeuchi et al, 2016 ), and self-reported oral health ( Masalu and Astrøm, 2002 , Yamane-Takeuchi et al, 2016 ).…”
