    • In an endodontic procedure, after the working of a root canal by instruments to remove material and shape the walls of the canal, irrigant is supplied to irrigate and clean the canal. A fluid is applied via a tube which is inserted partway down the root canal and a vacuum is supplied via the cannula. Alternately, the fluid may be supplied through the cannula and vacuum through the tube. The tube and cannula may or may not pass through a material created by a standard dental filling material of a composite nature which provides a seal at a position near the top of the coronal opening. The cleaning may be performed using a cannula having a slight taper with one or a series of larger holes near the top and smaller holes near the bottom; or a pair of cannulas of substantially the same diameter and taper, one with one or a series of larger holes near the top, while the other one with one or a series of holes near the bottom of the cannula.
    • 在牙髓治疗过程中,通过器械加工根管以去除材料并形成管道的壁,供应冲洗液以灌溉和清洁运河。 通过管子施加流体,该管子沿根管插入到中央部分,并且通过套管提供真空。 或者,可以通过套管提供流体并通过管子提供真空。 管和套管可以或可以不通过由复合性质的标准牙科填充材料产生的材料,该材料在靠近冠状开口顶部的位置提供密封。 可以使用具有稍微锥度的套管来进行清洁,其中在顶部附近具有一个或一系列较大的孔,靠近底部的较小孔; 或一对具有基本相同的直径和锥度的插管,一对在顶部附近具有一个或一系列较大的孔,而另一个具有靠近插管底部的一个或一系列孔。
