Abstract
With the acceleration of population aging in China, the incidence of root surface caries is increasing year by year. Different from coronal caries, lesions of root surface caries mostly occur on the exposed root surfaces after gingival recession in elderly patients, mainly involving cementum and dentin. Root surface caries shows specificity in the pathogenic characteristics, clinical manifestations, diagnosis, treatment, and prevention. This review mainly summarizes the etiology and prevalence, pathology and clinical manifestations, classification, as well as three-level-prevention of root caries, in order to provide relevant guidance for the clinical prevention and treatment of root caries.
