What does rootcap mean?
A rootcap is a dental cap fitted over the exposed root of a tooth. It may be used to seal the root, protect the tooth from decay or damage during treatment, or provide support for a larger restoration such as a crown. The term is most often encountered in dentistry and related technical discussion. Although “root cap” is also encountered as a two-word spelling, “rootcap” is commonly treated as a closed compound. The word is specific rather than general-purpose: it does not ordinarily refer to an architectural cap, clothing, or any other kind of cover placed at the base or bottom of an object.
