MELO, Tiago André Fontoura de; KUNERT, Gustavo Golgo; SILVA, Mireli Belizario da  and  CABEDA, Mariella Falci. Efficacy of two obturation techniques in experimental internal root resorption cavities. Rev. odontol. UNESP [online]. 2014, vol.43, n.6, pp.367-371. ISSN 1807-2577.


The filling with obturation endodontic material in teeth with internal root resorption is extremely difficult.


To evaluate the efficacy of two obturation techniques in the filling of experimental internal resorption cavities.

Material and method:

Twenty maxillary central incisors artificial, with the presence of a standardized simulated resorption cavity in the middle third of the root canal were used. After endodontic treatment of teeth, they were randomly divided into two groups (n=10), according to the obturation technique used: hybrid Tagger or with the aid of the ultrasonic system. Verification of endodontic obturation, with the cavity internal resorption, was taken by radiography with two types of incidence: mesiodistal and buccolingual. For the analysis of area closures, we used the Image Tool® program. The data of the filling were subjected to statistical analysis using Student's t test, with significance level of 5%.


There was no statistical difference between the tested obturation techniques. As one can observe a significant difference in teeth obturated with the aid of ultrasound, when compared to the radiograph performed in mesiodistal with buccolingual.


The two obturation techniques tested were similar to fill the cavity of internal resorption.
