ABSTRACT
The success of any endodontic treatment depends on a range of factors, including achieving good apical sealing, preparing the root canal using rotary nickel-titanium instruments in order to obtain mechanical preparations with tapers unlike those achieved using manual instrumentation. Three-dimensional sealing of the root canal is of the utmost importance, given that proper filling of the space created by the instrumentation prevents the microleakage of periapical exudate into the root canal. This in turn hampers the survival of residual and resistant microorganisms, thus contributing to the healing process and the success of the endodontic therapy. The single-cone technique is one that uses a single principal or master cone with different tapers. It has become popular among endodontists over the years due to its greater adaptability to the characteristics of nickel-titanium (NiTi) rotary systems without the need for accessory cones, which reduces working time and allows easier and faster filling, causing less fatigue for both the patient and the operator. However, in terms of quality of the obturation, apical microleakage, and bacterial penetration, this technique provides similar results to those achieved using other techniques. This review article is an attempt to highlight the advantages and disadvantages of using the single-cone technique to seal the root canal, considering the qualities of the endodontic sealer used. The single-cone technique has the advantage of saving time during root canal filling and being more comfortable for the patient and the physician alike.
