The authors conducted a review to evaluate the current literature addressing root surface caries treatment in the vulnerable elderly, to identify any gaps in the literature that will need to be addressed in the future. The authors conducted a literature search of the electronic databases using MEDLINE, PubMed, to identify original clinical research articles regarding treatment of root caries lesions, with emphasis on research focused on the vulnerable elderly. Five articles were clinical studies of root caries restorations. Only one was conducted on a vulnerable elderly population. The results of the literature review show that there is a need for further studies addressing the restorative needs of the vulnerable elderly. With the aging of the American population, more research is needed to provide adequate care to this population. At this time, glass ionomers are a good treatment option.
