Broaches endo12/31/2023 Bland clamps are less likely to impinge on the gingivae as they have flat jaws, which grip the tooth around its entire circumference. Retentive clamps are designed to make a four-point contact with the tooth they have narrow, curved and slightly inverted jaws, which may displace gingival tissue to grip the tooth below the level of greatest circumference they are very useful on partly erupted teeth. A winged clamp allows the attachment of the rubber dam to the clamp so that both clamp and rubber dam may be applied to the tooth together. Clamps are winged or wingless, retentive or bland ( Fig. There are also non-metallic clamps made of plastic (SoftClamp, KerrHawe, Bioggio, Switzerland) on the market. Most clamps are made from stainless steel some are made from plated steel, which may be more susceptible to corrosion by sodium hypochlorite. In endodontics, anchorage is the main requirement. A surgical haemostat may be used to position X-ray films, for radiography during treatment.Ĭlamps have two uses: first, they anchor the rubber dam to the tooth, and second, they retract the gingivae. A millimetre ruler or other measuring device should be available for measuring purposes. A flat plastic instrument and an amalgam plugger are needed for placement of an inter-appointment restoration. Both Briault and periodontal probes are necessary for the initial assessment of the tooth for caries and the localized periodontal condition. Locking tweezers are ideal for handling paper points, gutta-percha points, cotton wool pellets and root canal instruments. A long spoon excavator is required to remove pulpal contents and soft caries where present. The endodontic explorer is a double-ended, extra-long, sharp instrument designed to help in the location of canal entrances and for detecting fractures. A front-surfaced mouth mirror produces an undistorted image for good visibility deep within the pulp chamber. For convenience, a basic selection of instruments should be packaged or set-up in a tray, ready to use ( Fig.
