Root surface caries: a critical literature review.

Little information is available on the prevalence and clinical appearance of root surface caries. The literature shows that root surface caries is thought to be similar to coronal caries, but that certain diet-bacterial interactions might predispose to root surface caries. A scan of the literature concerning the epidemiology, etiology, microbiology, periodontology, as well as reporting methods and restoration treatment of root surface caries shows current practices and suggests future research.
