Abstract EN
Objective.
The objective of this study was to evaluate the efficacy of two retreatment NiTi systems (protaper universal retreatment files, R-Endo), when compared to manual technique in removing Gutta-percha obturated with two sealers.
Study Design.
Sixty extracted single-rooted premolars were instrumented with Protaper rotary files till F3.
The specimens were divided into six groups.
Groups 1, 2, 3 were obturated with Gutta-percha and zinc oxide eugenol and Groups 4, 5, 6 were obturated with Gutta-percha and AH-plus.
The retreatment was carried out in groups 1 and 4 with H-files and GGdrills, groups 2 and 5 with R-endo retreatment files and groups 3 and 6 with Protaper retreatment files.
The roots were sectioned and evaluated under optical stereomicroscope.
Statistical analysis was performed with one-way ANOVA and Newman-Keul's test at P<0.05.
Results.
The manual technique resulted in cleaner canal walls when compared with both rotary retreatment systems.
Conclusion.
NiTi rotary retreatment files can be used to remove the filling material quickly, but it should be followed by hand instruments to obtain better canal wall cleanliness.
