摘要： An intracoronal bristle brush for preparing a tooth cavum comprising a plurality of bristles and a dental bit having a first portion being a shank adapted to be received by a dentist's handpiece and a second portion for receiving the plurality of bristles. The plurality of bristles emanate outwardly in a uniform manner from an axial hole within the second portion. The diameter of the intracoronal bristle brush dental bit ranges from substantially uniform to a tapered diameter towards the second portion such that the bristles of the brush may penetrate into an interior surface of a tooth cavum.

摘要： An intracoronal bristle brush for preparing a tooth cavum comprising a plurality of bristles and a dental bit having a first end being a shank adapted to be received by a dentist's handpiece and a second end for receiving the plurality of bristles. The plurality of bristles emanate outwardly in a uniform manner from an axial hole within the second end. The diameter of the intracoronal bristle brush is substantially uniform along its entire length such that the bristles of the brush may penetrate into an interior surface of a tooth cavum.
摘要翻译：一种用于制备包括多个刷毛的牙槽的冠状刷毛，以及具有适于被牙医的手持件接收的柄的第一端的第一端和用于容纳多个刷毛的第二端的牙齿。多个刷毛以均匀的方式从第二端内的轴向孔向外散出。冠状刷毛的直径沿着其整个长度基本均匀，使得刷的刷毛可以渗透到牙槽的内表面。
