Interfase generada en el conducto radicular obturado con técnica de cono único de gutapercha y sistema de cono único hidrófilo

Abstract

Summary: The success of the endodontic treatment is fundamental for the physiological reintegration of the tooth into the stomatognathic system. Objective: To compare the interface generated in the obturated root canal with two single cone obturation systems: gutta-percha and hydrophilic cone. Methodology: A quasi-experimental invitro study was carried out on 66 samples, which were used to measure the interfaces between the obturation material and the canal wall, sealed with single gutta-percha and hydrophilic cone techniques subjected to thermocycling and observed under the electron microscope of scanning. Results: In the analysis of the specimens filled with gutta-percha, a minimum interface of 11.80 μm and maximum of 233.86 μm was found with an average of 61.45 μm. In relation to the hydrophilic cone, a minimum interface of 17.07μm, maximum of 766.78 μm and mean of148.67 μm was found. Regarding thermocycling, a statistically significant difference was found for gutta-percha (p = 0.07) and for the single hydrophilic cone (p = 0.544). Conclusions: The methods used allowed to observe the interface in the coronal , middle and apical thirds of the root canals sealed with single gutta-percha and hydrophilic cone technique, finding out that the single gutta-percha cone technique presented lower interface values in the thirds analyzed, being greater for both techniques the interface in the coronal third.
