dc.description	In the present investigation, the surface defects found in reciprocating files, Reciproc 25.08 and Wave One Gold Primary 25.07, were compared before and after using 3, 6 and 9 opportunities in the instrumentation of root canals with moderate curves of extracted human molars, under observation of MEB. Photographs of the apical third at 500x and of the middle and cervical thirds at 200x were rated by four endodontic experts, who identified defects such as microcracks, stretch marks, craters, deformation of sharp surfaces, blunt borders, presence of a smear layer and fracture of the instrument. The results were submitted to a Kruskal Wallis, chi2, ANOCA and t student statistical analysis, given the structure of the non-parametric variables, obtaining conclusions such as, that the Reciproc file has fewer surface defects than Wave One Gold; however, a direct relationship of these to the fracture was not found, since the Reciproc file broke more than the Wave One Gold, but statistically none of the two systems showed a significant fracture index in order to conclude that lime is more separated. A direct relationship was found between the number of surface defects and the number of uses of the instrument, therefore, it can be defined that fewer uses will have less surface defects and less risk of fracture, determining as a recommendation that this type of reciprocating rotary files can be used maximum for three opportunities.	en-US
dc.description	En la presente investigación se compararon los defectos superficiales encontrados en las limas de movimiento reciprocante, Reciproc 25.08 y Wave One Gold Primary 25.07, antes y después de usarlas por 3, 6 y 9 oportunidades en la instrumentación de conductos radiculares con curvaturas moderadas de molares humanos extraídos, bajo observación de MEB. Las fotografías del tercio apical a 500x y de los tercios medio y cervical a 200x fueron calificadas por 4 expertos endodoncistas, quienes identificaron defectos como microfisuras, deformación de estrías, cráteres, deformación de superficies cortantes, bordes romos, presencia de barrillo dentinario y fractura del instrumento. Los resultados se sometieron a análisis estadísticos Kruskal Wallis, chi2, ANOVA y de t student, dada la estructura de las variables, obteniendo conclusiones como, que la lima Reciproc presenta menos defectos superficiales que la Wave One Gold; sin embargo, no se encontró una relación directa de éstos con la fractura, puesto que la lima Reciproc se rompió más que la Wave One Gold, pero estadísticamente ninguno de los dos sistemas mostró un índice de fractura significativo para poder concluir que lima se separa más. Se encontró una relación directa entre la cantidad de defectos superficiales y el número de usos del instrumento, por lo tanto, se puede definir que, entre menos usos habrá menos defectos superficiales y menos riesgo de fractura, determinando como recomendación que se pueden usar este tipo de limas rotatorias reciprocantes máximo por tres oportunidades.	es-ES
