摘要： The invention concerns a dental instrument for performing root canal work. An end portion, integrally connected to the instrument shaft, is provided with four faces of like size, shape and orientation. The four faces are joined to one another by curved, continuous edges. Thus, the end portion has a square cross-section, provided so canal walls can be rasped at four points while leaving the walls of the canal smooth. Because the face edges meet at one point, a separate tip element is not necessary.
摘要翻译：本发明涉及用于进行根管工作的牙科器械。一体地连接到仪器轴的端部设置有具有相同尺寸，形状和取向的四个面。四个面通过弯曲的连续边缘彼此连接。因此，端部具有正方形的横截面，只要使得管道壁能够在四个点处被撬开，同时使管道的壁平滑。由于面边缘在一点相遇，所以不需要单独的尖端元件。

摘要： The invention is an improved disinfectant and sterilant in a chemical form. The disinfectant and sterilant formulation is based upon glutaraldehyde which must be in acidic form. The normal pH range for the disinfectant and sterilant is 3.0-3.5, however, under controlled circumstances the range may be 2.5-7.0; as the disinfectant and sterilant must be acidic, it cannot be over pH 7.0. In use as a disinfectant by immersion, the items or materials remain immersed for up to ten minutes. As a sterilant, the immersion is between six and ten hours. The disinfectant and sterilant consists of a plurality of chemicals mixed with the glutaraldehyde as a solution.
摘要翻译：本发明是化学形式的改进的消毒剂和灭菌剂。消毒剂和消毒剂配方基于必须呈酸性形式的戊二醛。消毒剂和灭菌剂的正常pH范围为3.0-3.5，但在受控情况下，范围可能为2.5-7.0; 因为消毒剂和灭菌剂必须是酸性的，所以不能超过pH 7.0。通过浸泡作为消毒剂使用时，物品或材料保持浸泡长达十分钟。作为灭菌剂，浸泡时间为6至10小时。消毒剂和消毒剂由与戊二醛混合的多种化学药品作为溶液组成。

摘要： The invention is an improved dental instrument for root canal condensation dental work. The instrument is self-contained in that it is a combination tool used as a spreader, a condenser, and a filling material heating unit, each of which is alternately and/or concurrently useable while inserted within the root canal structure of a patient. The invention provides several embodiments, each of which comprises: a plugger component (which use combines the functions of a spreader, a condenser, and a material heating unit); a handle component affixed to the plugger component; a power supply component for producing heat; and a transmission component for transmitting heat produced by the power supply component to the material heating unit of the plugger component. The transmission component has a conveniently located finger operation switch to interrupt the power supply and cut off the flow of heat. The plugger component is provided in a range of sizes to fit the range of internal sizes in different parts of the root canal.
摘要翻译：本发明是用于根管缩合牙科工作的改进的牙科器械。该仪器是独立的，因为它是用作扩张器，冷凝器和填充材料加热单元的组合工具，每个单元在插入到患者的根管结构内时交替和/或同时使用。本发明提供了几个实施例，其中每一个实施例包括：一个插头组件（该组件用于结合扩展器，冷凝器和材料加热单元的功能）; 固定在插头部件上的手柄部件; 用于产生热量的电源部件; 以及用于将由电源部件产生的热量传递到插头部件的材料加热单元的传输部件。传动部件具有方便的手指操作开关，以中断电源并切断热量。插塞组件提供的尺寸范围适合根管的不同部分内部尺寸范围。
