A com-parison of stress produced during lateral and vertical condensation using engineering models J Endodon ; Use of an electronic apex locator on a cardiac pacemaker patient.

Readings show a working waltoj shorter than the original work time length; this indicates a perforation. An chronometric X ray of the three canals is obtained, after that they are filled following cold lateral condensation technique and with epoxy resin based AHplus cement.

J Am Dent Assoc ; Small perforations are those prrincipios with endodontic instruments size 15 or Perforations are sealed with MTA and finally, radiographic evidence identifies the perforations’ sealing Figure 5.

Oral Surg ; An in vitro evaluation of the accuracy of the root ZX in presence of various irrigants.

The best time to repair root perforations is immediately after the accident occurs, minimizing thus the potential of infection at the perforation site. Negative response was obtained to hot and cold pulpal sensitivity tests Figure 1.


A clinical evaluation of endocater. After fine months the tooth is restored, with proper bone regeneration in the furcation zone. The site is cleansed with physiological solution. From this case we dndodoncia conclude that the sooner the repair is carried out, the greater will be the possibility of success. Nonsurgical repair of perforation defects.


A final X ray is taken to examine the mesiolingual mL guttapercha and the temporary seal of the perforations carried out with cavit Figure 4.

Comparison of the sealing ability of laser softened, laterally condensed and low-temperature thermoplasticized gutta-percha J Endodon ; While undertaking endodontic procedures, setback can occur. In general terms, direct perforation occurs during the canal exploration. Phases I and II: Apical extent of rotary canal instrumentation with an apex- locating hand piece in vitro. Periodontal effects of root perforations before and during endodontic procedures. Root canal treatment is associated with unforeseen and unwanted random circumstances, these are generally defined as procedure accidents.

It is rather a ”puncture” in the bifurcation carried out with the burr. Marciano J, Michailesco PM. Clinically, we can observe the restored tooth with a full crown free of metal, healthy gums, and when probing the middlevestibular third, we find 4 mm.

Pathological causes like root resorption and caries can lead to a perforation. Tri Auto ZX in locating apical foramen with rotary. In these cases a proper temporal seal should be established to avoid bacterial passage. Analy-sis of the forces developed during obturation: Marlin J, Schilder H.

A radiolucent area was also observed in that area. Radiovisiography versus conven-tional radiography for detection of small instruments in endodontic length deter-mination. Prevention is endidoncia most important factor to avoid accidents during endodontic therapy.

Avoid use of rotary instruments. These accidents are defined as unfortunate events taking place while performing endodontic therapy. J Endod ; Part of these are perforations in the cervical section of the canal, and misadventures related to obturation, among which we find overextended or underextended obturation of root canals.


Upon inspection, a metal free restoration and an apparently healthy gingival are observed. Ingle J, Bakland L. Kaufmann considers it a reliable instrument and essential factor for treatment success.

Some of these unfortunate events are perforation in the chamber of the floor of the mouth, or poor obturation of the canal system, which will lead to failure of the treatment. After this, curetting is carried out on the furcation zone to remove granular tissue. Treatment outcome in endodontics: La radiovisio-grafia en endodoncia.

Scanning electron microscopic evalua-tion of two compaction techniques using a composite resinas a root canal fillig material J Endodon ; Rodriguez Ponce defines it as the obturation of the root canal away from the work length determined by a previous conductometry radiograph, this will lead to an endodontic failure. With the help of Hedstrom files the distal canal where underobturation is present is cleared. A comparative study of the sealing ability of two root canal obturation techniques J Endodon ; There are to be used only when the case warrants it and the canals are sufficiently wide.
