Root canal treatment (also known as endodontic therapy, endodontic treatment, or root canal therapy) is a treatment sequence for the infected pulp of a tooth which results in the elimination of infection and the protection of the decontaminated tooth from future microbial invasion. Root canals, and their associated pulp chamber, are the physical hollows within a tooth that are naturally inhabited by nerve tissue, blood vessels and other cellular entities. Together, these items constitute the dental pulp. Endodontic therapy involves the removal of these structures, the subsequent shaping, cleaning, and decontamination of the hollows with small files and irrigating solutions, and the obturation (filling) of the decontaminated canals. Filling of the cleaned and decontaminated canals is done with an inert filling such as gutta-percha and typically a eugenol-based cement. Epoxy resin is employed to bind gutta-percha in some root canal procedures. Endodontics includes both primary and secondary endodontic treatments as well as periradicular surgery which is generally used for teeth that still have potential for salvage.

Endodontic gutta-percha point with working length marks
InactiveUS7097454B1Accurate insertionTeeth fillingWheelchairs/patient conveyanceEndodontic therapyEndodontist
A gutta-percha point, used as a root canal plugging material in an endodontic treatment, is disclosed. The gutta-percha point has a plurality of engraved or embossed marks as working length marks on its upper portion. Each of the engraved or embossed marks is preferably painted with a distinguishable color along a circumferential surface. The above marks are formed on the point within a marking range while being spaced out at intervals of 1 mm and 2 mm. The marking range starts at a position, spaced apart from the apex of the point by 18 mm, and ends at a position spaced apart from the apex by 24 mm. The gutta-percha point thus allows an endodontist to be free from a repeated marking of working lengths on such points during an endodontic treatment, thus allowing the endodontic treatment to be accomplished within a desired short period of time. Due to the working length marks, the gutta-percha point is precisely inserted into an access cavity of a decayed tooth by a desired depth, thus being free from forming a dead space in the root canal or piercing the apical tissue.

The method and extractor relate to dentistry and are intended for extraction of metal instruments fragments from a root canal of the tooth, as these instruments may be broken and may get stuck here, for example, during endodontic treatment. According to the invention, two insulated metal electrodes assembled as a cylinder are inserted into the root canal until electric contact with the fragment to be extracted. Then electric current impulse is ran through the circuit formed by the first electrode, metal fragment and second electrode; the intensity and duration of the electric impulse shall be sufficient for welding of the fragment to the electrodes by means of heating at the contact points; this time a heating of the surrounding tissues remains at the physiologically acceptable level; afterwards the electrodes are extracted from the root canal together with the fragment. Depending on a clinical situation, electrodes of various size and configuration are used. Electric impulse is generated by the unit comprising a capacitor chargeable by a battery and dischargeable in pulsed mode via controlled electronic switch. The unit also has an indicator of contact resistance between the fragment and the electrodes for a better alignment of their relative positions.
