Abstract
An improved dental scaler or curette wherein the cutting blade is spaced from the handle of the instrument by an arcuately formed shank portion which extends outwardly from the lower portion of the handle in a generally continuous arc to a relatively straight portion that extends transversely at an obtuse angle with respect to the plane of the arcuate shank and from which the cutting blade of the instrument extends at an acute angle with respect to the plane of the arcuate shank. In a further embodiment, the cutting blade includes a concave or generally V-shaped portion extending inwardly of the cutting edge thereof so as to form an elongated trough or trap in which material may be retained for removal during scaling or scraping of a tooth surface.
