摘要： A dental cartridge for dispensing a dental material having a body portion made of a material transparent to at least a portion of the visible light spectrum and opaque to the actinic light of the dental material contained therein. Also, a dental cartridge having a body portion formed from a toroidal segment and a coaxial nozzle attached thereto. The dental cartridges are used in a dental syringe for application of the dental material to a patient. Several embodiments provide various discharge end configurations, including hemispherical, conical frustum, and flat. Additionally, dosing indicia are placed on the body portion of the dental cartridge, permitting the dentist to fill the dental cartridge with a predetermined volume of dental material. A specially configured piston having an appendage thereon is used in combination with the dental cartridge for extruding substantially all of the costly dental material therein.

摘要： A method and apparatus for delivery of highly filled, thixotropic resin sealant to tooth surfaces. The apparatus includes a dispenser for holding a quantity of the sealant material and a delivery tip having adjustable bristles at one end. The bristles are slidably secured in a spiral passageway formed by a helical ridge inside the delivery tip, thereby allowing the sealant material to be continuously applied without the need to stop the procedure and rewet the applicator. The applicator permits accurate control of the amount of sealant material applied to the surface. In this way, the surface receives neither an excessive nor an insufficient amount of the sealant material. Moreover, the bristles may be pushed in to permit the sealant material to be applied to a small, irregular surface, such as pits and fissures, or pulled out to permit the bristles to fan out for application to broad surface areas. Delivery of highly filled, relatively viscous, thixotropic sealant materials is made possible by providing the spiral passageway around the bristles so that the coating material does not have to flow through the bristles, and due to sheer thinning caused by forcing the thixotropic material through the spiral passageway.
摘要翻译：一种用于将高填充的触变性树脂密封剂递送到牙齿表面的方法和装置。该装置包括用于保持一定量的密封剂材料的分配器和在一端具有可调节刷毛的输送末端。刷毛可滑动地固定在由输送尖端内部的螺旋形脊形成的螺旋通道中，从而允许密封剂材料连续施加，而不需要停止该过程并再次润湿涂抹器。涂布器允许精确控制施加到表面上的密封剂材料的量。以这种方式，表面既不受到过量也不足够的密封材料。此外，刷毛可以被推入以允许密封剂材料施加到诸如凹坑和裂缝的小的不规则表面，或者拉出以允许刷毛扇出以用于宽的表面区域。通过在刷毛周围设置螺旋通道使得高填充，相对粘稠的触变密封材料的输送成为可能，使得涂层材料不必流过刷毛，并且由于通过迫使触变材料通过螺旋而引起的纯粹变薄通道。

摘要： For free-hand use by a dentist, there is provided a cylinder containing tooth filling material urged out of the cylinder by spring pressure, sometimes augmented by thumb pressure against the end of a piston rod in the cylinder. Flow of the material out of the cylinder through a removable and replaceable flexible curved nozzle is under control of a valve located to be readily manipulated between open and closed positions by the same hand of the dentist. Preferably the filling material is in a discrete capsule containing enough filling material for several teeth and easily placed in and removed from the cylinder.

摘要： An apparatus which can be used for exposing a light-curable dental composition to a curing light to harden the composition while the composition is applied to teeth so that the exposure of dentists' or technicians' eyes to such light is minimized. The apparatus has an opaque cylindrical receptacle which is open at its top and bottom. The bottom opening allows the receptacle to pick up and discharge the dental composition. The working end of an elongated plunger, having a clear plastic core and an opaque surface coating, extends through the top opening of the receptacle, and the other end of the plunger is connected to a source of curing light. The working end of the plunger can irradiate the dental composition within the receptacle with the curing light and can also be moved within the receptacle to force the irradiated dental composition outward of the bottom opening in the receptacle onto a tooth.

摘要： A dental syringe for the dispensing of a relative viscous dental material that includes a readily replaceable barrel portion that defines a reservoir for containing a bulk supply of a dental material having a spout or nozzle discharge end to which a dispensibly nozzle tip is detachably connected and which barrel portion is sealed by a displaceable plug. A plunger is provided for effecting the displacement of the plug for effecting the extruding of the material from the barrel portion as needed, and which plunger has formed on the end thereof a unidirectional vent arrangement which is operative for imparting a negative pressure on the end plug to permit a slight rearward displacement thereof to relieve the back pressure exerted on the plug by the material upon the termination of an extruding operation and thereby prevent drooling of any unwanted material subsequent to an extruding operation.

摘要： The specification discloses an amalgam carrier for pushing amalgams into previously difficultly accessed tooth cavities such as in distal and lingual surfaces. The carrier includes an elongated handle, a support arm extending laterally of the handle, and a release mechanism mounted on the support arm and defining an amalgam bore opening away from the support arm in a direction generally common with the handle. The release mechanism is actuable in the vicinity of the support arm whereby the carrier can be firmly grasped about said handle and the release mechanism actuated by the user's thumb. Also disclosed is a method of pushing an amalgam utilizing the amalgam carrier of the present invention.

摘要： A dental implement for dispensing and compacting amalgam includes separate dispensing and compacting assemblies at opposite ends of a handle. The assemblies each have an amalgam carrier cooperating with a plugger portion which extends from an end of the handle. A spring-biased lever maintains the amalgam carrier in a normally lowered position capable of receiving amalgam. Each assembly features a lock for releasably retaining the amalgam carrier in a raised position whereby the plugger portion extends beyond its respective amalgam carrier for tamping the amalgam into a tooth cavity.
