Cognitive function was assessed using the Montreal Cognitive Assessment Hong Kong Version, One\u2010minute Verbal Fluency Task and Hayling Sentence Completion Test. Objective and subjective speech assessments were carried out using artificial intelligence speech recognition algorithm and a self\u2010designed speech questionnaire. The impact of tooth loss on psychosocial condition was evaluated by the Reading the Mind in the Eyes Test and a self\u2010designed questionnaire. Statistical analyses (one\u2010way ANOVA, ANCOVA, Kruskal\u2013Wallis test, Spearman correlation test) were performed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Tooth loss was significantly associated with lower cognitive function (<jats:italic>p<\/jats:italic>\u2009=\u2009.008), speech accuracy (<jats:italic>p<\/jats:italic>\u2009=\u2009.018) and verbal fluency (<jats:italic>p<\/jats:italic>\u2009=\u2009.001).
