Single-cone obturation technique: a literature review

Resumo

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.
