    Abstract: A device for delivering an irrigant and/or a medicament fluid to the gingival sulcus comprises an elongated handle member terminating in a flexible tip portion provided with aperture(s), the tip being connected to a fluid reservoir via a conduit and operable to discharge the fluid through the apertures only on the application of pressure to the reservoir and/or opening of a normally closed valve or apertures in the tip by flexing the tip, e.g., by pressing same against a tooth. In preferred embodiments, the handle is tubular, the distal end portion thereof comprising the fluid reservoir.

    Abstract: A toothbrush whose tufts comprise three distinct kinds of rows, with each row oriented transversely to the longitudinal axis of the head. The tufts of the first kind are the shortest. The endmost tufts on each row of the second kind tilt laterally outwardly by about 12 degrees. The tufts of the third kind are nearest the end of the head farthest from the handle and diverge from each other, with each tuft thereof tilting laterally at an angle of about 30 degrees and forwardly at about 14 degrees. In a first embodiment, each row of the first kind comprises a single, wide tuft. In a second embodiment, each row of the first kind has a plurality of laterally spaced round tufts. In a third embodiment, each row of the first kind comprises a plurality of laterally spaced rectangular tufts. All of the tufts may also be considered as defining four functional groups of tufts, with each of these four groups performing a specific function during brushing. The arrangement and orientation of the tufts yields a uniform cleaning action substantially independent of brushing direction or technique.

    Abstract translation: 一种牙刷，其刷毛簇包括三种不同种类的行，每一行横向于头部的纵向轴线。 第一类的簇是最短的。 第二种类型的每一行的最末端的一束向外横向倾斜大约12度。 第三种类型的簇最靠近距离手柄最远的头部的端部，并且彼此分开，其每一簇以大约30度的角度横向倾斜并且以约14度向前倾斜。 在第一实施例中，第一种类型的每一行包括单个宽的簇。 在第二实施例中，第一种类型的每行具有多个横向间隔开的圆形簇。 在第三实施例中，第一种类型的每行包括多个横向间隔开的矩形簇。 所有的簇也可以被认为是定义簇的四个功能组，这四组中的每一个在刷牙过程中都具有特定的功能。 刷毛束的布置和取向产生基本上与刷洗方向或技术无关的均匀的清洁作用。
