Introduction: Endodontic treatment is performed daily in various health centers by specialists and general dentists, however, the obturation treatment can fail and a deobturation of the materials lodged in the root canals whether straight or curved is required. Objective: To determine which of the two systems Reciproc Blue and WaveOne Gold is more effective in the deobturation of curved root canals by means of a literature review of related studies. Method: Qualitative and descriptive literature review with scientific articles obtained from the PubMed online database as the study population. Results: WaveOne Gold presented a minimum time of between 2.03 and 4.9 min in the duration of the cleaning of curved root canals, while Reciproc Blue presented a time between 3.21 and 5.4 min. Conclusions: It was determined that the two systems Reciproc Blue and WaveOne Gold have a good efficacy in the treatment of deobturation of curved root canals, since they eliminate the materials lodged in these canals after an incorrect obturation, with cleaning percentages higher than 2%.
