A cross\u2010sectional study was conducted on 400 patients (200 with cognitive impairment and 200 age\u2010 and sex\u2010matched controls) attending the Paediatric Dentistry and Orthodontics Unit of the Policlinico Gemelli\u2013Italy. Clinical examination was performed to assess signs of bruxism and prevalence of malocclusions; questionnaires were used to collect information on bruxism and OSA risk. Patients with cognitive impairment showed a significantly higher prevalence of both sleep bruxism (SB) (20.5% vs. 13.0%;\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.044) and awake bruxism (AB) (13.0% vs. 2.5%;\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.0001). Among paediatric patients with cognitive impairment, high OSA risk was significantly associated with SB (OR\u2009=\u20093.5;\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.008). In addition, malocclusions were significantly more frequent in patients with cognitive impairment. Overall, bruxism is associated with cognitive impairment, despite distinct patterns being observed between SB and AB. Due to the association between OSA risk and SB specifically in the paediatric subgroup and to the high prevalence of malocclusions in patients with cognitive impairment, a multidisciplinary approach is suggested in this population.\n                  <\/jats:p>","DOI":"10.1111\/jsr.70427","type":"journal-article","created":{"date-parts":[[2026,7,29]],"date-time":"2026-07-29T02:19:22Z","timestamp":1785291562000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Prevalence of Bruxism in a Mixed Paediatric and Adult Population With Cognitive Impairment: A Large Cross\u2010Sectional Study"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2210-1403","authenticated-orcid":false,"given":"Anna","family":"Alessandri\u2010Bonetti","sequence":"first","affiliation":[{"name":"Department of Head and Neck and Sense Organs A.
