    • This invention is directed to a dental instrument and the use of this dental instrument to measure deposits and other imperfections on a tooth surface. The dental instrument has an elongated portion and on at least one end a general curvature portion. The general curvature portion will have the general curvature of a posterior tooth or an anterior tooth. Preferably it also will be marked with measured segments. By placing the general curvature portion against a tooth a deposit or imperfection on a tooth can be measured. In a preferred embodiment the dental instrument will have a general curvature portion in each end; the general curvature on one end being for posterior teeth and the general curvature on the other end being for anterior teeth. When measuring plaque and related deposits a dye solution can be used to make the deposit more visible.
    • 本发明涉及一种牙科器械以及该牙科仪器用于测量牙齿表面上的沉积物和其它缺陷的用途。 牙科器械具有细长部分,并且在至少一个端部具有总体曲率部分。 一般弯曲部分将具有后牙或前牙的一般曲率。 优选地,它还将被标记有测量段。 通过将一般弯曲部分放置在牙齿上,可以测量牙齿上的沉积物或缺陷。 在优选实施例中,牙科器械在每个端部中将具有一般的曲率部分; 一端的一般曲率为后牙,另一端的一般曲率为前牙。 当测量斑块和相关沉积物时,可以使用染料溶液使沉积物更可见。
