PEREIRA, Andréa Cardoso; NISHIYAMA, Celso Kenji  and  PINTO, Lidiane de Castro. Single-cone obturation technique: a literature review. RSBO (Online) [online]. 2012, vol.9, n.4, pp. 442-447. ISSN 1984-5685.

Introduction: The technique of single-cone obturation is a technique that uses only the master cone. There have been an increase in its use, especially by employing larger cones with larger taper sizes that best match the geometry of rotary nickel-titanium systems (NiTi), not requiring the use of accessory cones, thus reducing the time spent in endodontic obturation. Objective: To review the literature on this technique and to compare it with other existing techniques, as well as to elucidate its advantages and disadvantages. Literature review: The single-cone obturation technique enables an easier and faster endodontic obturation. However, regarding to the aspects such as the obturation quality, apical microleakage and bacterial penetration, this technique is similar to or lower than others. Conclusion: This technique has the advantage of saving time during the filling of the root canal. However, further studies are necessary to evaluate its prognosis, especially in canals with complex anatomy.
