Abstract:

With the development of aging, multimorbidity has become increasingly prominent, and its association with oral health has gradually attracted attention. Oral health is a good predictor of multimorbidity. This paper aims to review the research progress based on the association and statistical methods, and clarify further research emphasis. Compared with studies abroad, Chinese researchers pay insufficient attention to the association between oral health and multimorbidity. Regarding research content, current research focuses on simple association between oral health and multimorbidity, and has not yet established a consensus on multimorbidity, nor explored an in-depth association between oral health and multimorbidity. As to statistical methods, the majority research is based on regression analysis or logistic regression, and less is used for cutting-edge statistical analysis methods. In the future, it is necessary to establish a consensus on multimorbidity, use clustering or other methods to explore the multimorbidity, further use cutting-edge machine learning and deep learning technologies to explore the association between oral health and multimorbidity, analyze its pathogenesis, and provide an evidence-based basis for the formulation of oral-centered interventions.
