Abstract: A root canal is sequentially cleaned in sections from the crown to the apex by dividing it into three sections including an operative coronal portion, an operative middle portion and an apical portion. After an opening is formed into the tooth to provide access into the root canal, the opening is preferably rectified to remove obstructions so that the anatomical root canal can be fully accessed. The pulp material is then sequentially removed from the portion of the root canal above the apical portion of the root canal with a set of instruments (410). The apical portion is then cleaned with another set of instruments (470). An optional set of instruments (440) can also be used to improve the access into the apical portion such that irrigants can be delivered to the apical portion. Cleaning of the pulp material from the root canal also shapes the root canal to ease filling of the root canal with a filling material. The root canal preparation and shaping are completed while maintaining the original anatomy of the root canal. Each file has an abrading portion and terminates at a tip. The files of the set (410) of instruments used to clean the portion of the root canal above the apical portion have properties which enable the abrading portion of the file to conform to the configuration of the root canal while simultaneously moving the file in a cleaning motion.

Abstract: Water and aqueous sodium hypochlorite indicating endodontic monitoring devices include an endodontic cone formed of a water absorptive material and a color changing system applied to the material that changes to different colors when exposed to water or aqueous sodium hypochlorite within a root canal chamber. The water-indicating endodontic cone includes a water absorptive material capable of indicating a change in pH, and a pH insensitive dye. The dye imparts an initial color when the cone is in a dry condition. The pH changing material and pH indicator react in the presence of moisture in a root canal to yield a second color different from the initial color. In the presence of aqueous sodium hypochlorite, the cone changes to a third color different from both the initial color and the second color as a result of bleaching of the dye and/or pH indicator by the hypochlorite ions or aqueous analogs.

Abstract: A dental treatment system (100) comprises membrane treatment tray (102) that is self-conforming to a person's own teeth when used with a sticky dental treatment composition and a support skeleton (104). The support skeleton (104) maintains the flexible membrane tray (102) in the form of tray prior to placing the tray over a person's teeth. A sticky viscous composition is either provided in or applied to the membrane tray (102), and then the treatment system is placed so as to position the membrane tray over the upper or lower teeth of the person. The support skeleton (104) (internal or external) is separated from the membrane tray (102) so that just the membrane tray (102) remains over the person's teeth during the desired dental treatment. The sticky viscous composition holds the membrane tray (102) against the teeth and helps it to at least partially conform to the shape of the teeth. The membrane dental tray is useful for teeth bleaching and other dental treatments known in the art.

Abstract: A bite block system (170) for maintaining the mouth of the patient in an open position during a dental procedure. In one embodiment, the bite block (90) includes a plastically deformable material on at least a surface thereof for making an impression of the patient's teeth. Such customized bite blocks (90) provide greater safety and comfort. In another aspect, a tongue suppressing bite block system (170) includes a bite block (90) and a tongue suppressor (160) adjustably attached thereto so that the tongue suppressor (160) can be adjusted horizontally or vertically relative to the bite block (90) to account for variations in the size of patient's mouths, teeth and tongues. In another aspect of the invention, an anatomical tongue suppressor (160) is provided for use with a bite block (90). The anatomical tongue suppressor (160) wraps around the side and underneath the tongue in order to cradle it in a more comfortable and secure fashion when in use with a bite block (90). The anatomical tongue suppressor (160) may optionally include a saliva aspiration port that permits the aspiration of saliva through one or more lumens within the tongue suppressor.

Abstract: An endodontic irrigator tip (20) having a cannula (60) with an annealed distal portion (65) and a proximal portion (63) enables the cannula (60) to easily move within a root canal. The cannula (60) extends from a hub (22) that is adapted for coupling with a syringe or other delivery device. The cannula (60) has an outlet orifice for delivering an irrigant out of the endodontic irrigator tip and into the root canal. The outlet orifice may be defined by a rounded rim that optimally enables the distal insertion end of the cannula to be advanced within the root canal.

Abstract: Dental treatment devices for treating a person's teeth and/or gums include a barrier layer with a thickened occlusal wall that is at least about 10%, 20%, 30%, 40%, or 50% thicker than the labial and lingual walls. The thickened occlusal wall assists the user when installing the treatment device and helps retain the treatment device over the teeth during use. The barrier layer has a generally horseshoe-shaped and is devoid of structures corresponding to the size and shape of a person's unique dentition so as be adaptable and conformable over a plurality of differently-sized dental arches corresponding to different people. The dental treatment device may be initially separate from the dental treatment composition or pre-filled within the composition. Kits include one or more dental treatment devices and one or more treatment compositions. Methods include positioning a barrier layer and treatment composition over a person's teeth for a desired time period.

Abstract: Prefabricated non-custom dental appliances, kits, and methods that allow a practitioner to select one or more prefabricated non-custom appliances having desired color shading characteristics from a kit and bond the selected appliances to a person's teeth. Each appliance (100) includes a form layer (102) including a surface contoured so as to approximate a tooth surface (e.g., the labial surface shape of a selected tooth). The appliance includes a plurality of at least partially uncured composite layers or regions (104a, 104b). At least one of the composite layers or regions (104a) is disposed adjacent to the form layer (102), and each region (104a, 104b) is prearranged relative to one another so as to provide a predetermined overall color shade configuration. At least one of the composite layers or regions (104b) differs in color from at least one other composite region (104a) so as to provide a desired shade and intensity to the dental appliance.

Abstract: Dental instruments (210) made from a super-flexible alloy, which includes atoms from the group IVB and group VB transition metals and oxygen have superior strength and flexibility. The metal alloys are cold worked to increase the tensile strength of the dental instruments (210). Cold working the metal also increases the flexibility of the dental instruments (210). In one particular example a super-elastic endodontic file (210) is described.
