“…Poor gingival health, with inflammation and bleeding of the gums, was frequently reported in adults with intellectual disabilities and this relates to the level of plaque control. Many of these studies involved dental service users (Alves et al 2016;Batista, Moreira, Rauen, Corso, & Fiates 2009;Finkelman, Stark, Tao, & Morgan 2014;Özgül et al 2014;Seirawan, Schneiderman, Greene, & Mulligan 2008;Zizzi et al 2014), and in four papers, a high prevalence of daily toothbrushing was reported (Fernandez, Descamps, Fabjanska, Kaschke, & Marks 2016;Hsieh, Murthy, Heller, Rimmer, & Yen 2018;Margaritis, Koletsi-Kounari, Mamai-Homata, & Kiriakou 2012;Seirawan et al 2008). Of the clinical studies assessing the more severe form of periodontal health (periodontitis), a significant level of disease was recorded, with the prevalence in adults with intellectual disabilities ranging from 22.5% to 69.2% (Alves et al 2016;Cheng, Leung, & Corbet 2008;Davies et al 2008;Finkelman et al 2014;Margaritis et al 2012;Martinez-Martinez et al 2013;Moosani et al 2014;Morgan et al 2012;Özgül et al 2014;Zizzi et al 2014).…”
