From this case we can conclude that the sooner the repair is carried out, the greater will be the possibility of success. Another aide for perforation diagnosis is prxctica electronic apexes localizer.

In the distal canal underobturation was found as well as guttapercha points in the furcation zone. Int Endod J ; Avoid use of rotary instruments. Among accidents with worse prognosis are perforations at bone crest level, specifically in the furcation since its proximity to the gingival sulcus favors bacterial contamination.

Some of these events are a result of poor attention to detail, others are totally unpredictable.

Among the causes leading to this type of perforation are the lack of dental and pulpar anatomy, and, of utmost importance for endodontists, lack of radiographic information. How to cite this article.

It is not always possible to properly handle the perforation because of the operator’s lack of experience, or lack of proper equipment for its treatment. Detection of a root perforation requires a combination of symptomatic findings, clinical observation and diagnostic means.

Analy-sis of the forces developed during obturation: As a response to periapical sensitivity tests, principio palpation, to vertical and horizontal percussion, a positive response is elicited, with grade 1 mobility.


Endod Dent Traumatol ; An in vitro comparison of two modern apex locators. Small perforations are those caused with endodontic instruments size 15 or Localizadores apicales en endodoncia. In recent studies, a research group in Toronto found that in re-treatment cases only two factors significantly affected success in treatment: The four circumstances to consider when treating endodontic accidents endodonncia are: Retraction was undertaken and final prijcipios was carried out with 2.

Radiographic findings show non obturated mesial canals and walhon circumscribed periapical rarefaction. The effects of sodium hypochlorite concentrations on the accuracy of an apex locating device. Periodontal effects of root perforations before and during endodontic procedures.

With the help of Hedstrom files the distal canal where underobturation is present is cleared. A clinical and roentgenological study of 55 cases of root perforation. J Endod ; Electronic detection of root canal constriction J Endod ; 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.

Prognosis for a perforated tooth depends on the location of the perforation, the time in which the perforation allows entry of contamination, the possibility of sealing it and the accessibility of the main canal. An in vivo evaluation of root ZX electronic apex locator.

After 12 months, radiographically, the repair of the defect is almost complete. Classification and treatment choices based on prognosis factors. Use of an electronic apex locator on a cardiac pacemaker patient. In-fluence of the removal of coronal gutta–percha on the seal of root canal obtura-tions. Radiovisiography versus conven-tional radiography for detection of small instruments in endodontic length deter-mination.


While undertaking endodontic procedures, setback can endodooncia. Influence of the canal contents on the electrical assisted determination of Length of Root Canals. Finally a comparative follow up is carried out 21 months after finishing treatment and initial radiographic study Figure 7.

Accuracy of an electronic apex locator: Lateral condensation stress in root canals J En-dodon ;7: Problems encountered in tooth isolation and access to the pulp chamber space.

The thermomechanical properties of gutta–percha III. New electronic canal measuring deveice based on the ratio method. Diagnosis and treatment of accidental root perforations. Perforations are sealed with MTA and finally, radiographic evidence identifies the perforations’ sealing Figure 5.

Surgery can also be contemplated in cases where coronary guttapercha removal from the furcation is not possible. Mesiolingual guttapercha ML is extracted exclusively through a coronary approach, with a K type file, mesial canals are located with the help of an endodontic microscope, and perforations are temporary sealed with cavit.

Root canal, drilling, mineral trioxide aggregate. Treatment plan consisted in coronary or orthographic removal of the guttapercha present in the furcation after that, canals were retreated, the perforation was sealed with Mineral Trioxide Aggregate MTA.
