Comparison of the sealing ability of laser softened, laterally condensed and low-temperature thermoplasticized gutta-percha J Endodon ; Fuss Z, Trope M. Physical properties of gutta-percha when subjected to heat and condensation Parctica Surg ; With the help of Hedstrom files the distal canal where underobturation is present is cleared. We orincipios a clear improvement from the moment of initial treatment, and, 15 months after surgery we encounter good regeneration of the bone defect as well as sealing of both perforations Figure 6.

Reliability of electronic apex locator to determine the working length under moisture conditions. In the distal canal underobturation was found as well as guttapercha points in the furcation zone.


Oral Surg ; Jenkins W, Schindler F. After 12 months, radiographically, the repair of the defect is almost complete. 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.


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.

While undertaking endodontic procedures, setback can occur. A perforation can be detected through indirect means such as paper points or the radiographic image of a file prrincipios the bone or periodontal ligament.

Be cognizant with the pulpal anatomy of the tooth to be treated, proper access to be gained the chamber and guidelines for instrument use. Electronic detection of root canal constriction J Endod ; Nevertheless, the source is very often iatrogenic, as a result of an excessive use of the dental burr in the pulp chamber.

The walfon properties of gutta–percha III. In vitro evaluation of the reliability of de Endex electronic Apex locator.

When probing, a 9 mm periodontal pocket is detected in the vestibular middle third. A critical evaluation of some methods of determining tooth length. From this case we can conclude that the sooner the repair is carried out, the greater will be the possibility of success. An in vitro evaluation of the accuracy of the root ZX in presence of various irrigants. Editorial Harcourt – Mosby.

If organic residues remain in the canal the most frequent underobtuation causes are the creation of too short a stop, the lack of exact fit of the master cone, and lack of penetration of the filling material up to the predetermined work length.


Apical extent of rotary canal instrumentation with an apex- locating hand piece in vitro. J Endod ; Tri Auto ZX in locating apical foramen with rotary. 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.

Microbiological Study of Cast Posts before Cementation

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. Servicio de ayuda de la revista. Referencias West J, Roane J. Int Endod J ; She informs of root treatments carried out 3 months ago, she complains of nocturnal, spontaneous and localized pain when chewing. A clinical and roentgenological study of 55 cases of root perforation.

As a response to periapical sensitivity tests, to palpation, to vertical and horizontal percussion, a positive response is elicited, with grade 1 mobility. 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.

It is rather a ”puncture” in the bifurcation carried out with the burr. West J, Roane J. Treatment outcome in endodontics:
