Direction to Use

Lateral compaction of warm gutta-percha
A simple modification to the cold lateral compaction technique is to apply heat to the gutta-percha.
The softened material is easier to compact and will result in a denser root filling. However, finger spreaders will not retain heat sufficiently for
this procedure, and specially designed heat carriers should be used. The instruments have a sharp tip for lateral compaction, and a blunt plugger tip
for limited vertical compaction of the softened gutta-percha. Electrically heated spreaders are also available. It is important that the instruments are
only gently warmed. If the spreader is too hot it will melt the gutta-percha, which will adhere to the instrument and be withdrawn from the canal.
The main advantages of thermoplasticized gutta-percha techniques include better adaptation to root canal complexities,
lower risk of void formation and creating a dense filling.

Vertical compaction of warm gutta-percha
Heated gutta-percha has been shown to flow extremely well into all canal irregularities. It is particularly useful in situations such as internal resorption,
C- shaped canals, and those with fins or webs. As referred to earlier, when the smear layer is removed the gutta-percha has been shown to penetrate dentine tubules. This technique is now considered the gold standard for endodontic obturation. The principle of vertical compaction of increments of warm gutta-percha was first described by Schilder in 1967. Although delivering excellent results, the method was difficult to master and time-consuming.
. A non-standardized (4%, 6%, or feathered tip) gutta-percha cone is carefully fitted to the canal.
Using a selected plugger, a continuous wave of heat is applied to soften and down pack a cone,
resulting in very well-compacted obturation of the apical portion of the canal. The remainder of the canal may be obturated by further increments,
or by another method. When the ring on the handpiece is pressed as shown the tip of the plugger is immediately heated to the temperature selected

Single gutta-percha point and sealer
With the tendency to preparation techniques of greater taper, gutta-percha points of matching taper may be used. These fit the prepared canal so well that some operators are using a single gutta-percha point and sealer. The only advantage of this technique is its simplicity. The disadvantage is that the majority of sealers are soluble. As the canal will not be fully filled in three dimensions, tissue fluids may leach out the sealer over time. This technique cannot, therefore, be recommended. However, in difficult anatomical cases, it may be necessary to create a custom-fitted cone. A slightly large cone is selected and the apical part softened, either by solvents such as chloroform, rectified turpentine, or oil of eucalyptus or by immersion in hot water. The softened cone is fitted to working length with gentle pressure. The cone is carefully marked for orientation, and the process is repeated until a satisfactory fit is obtained. The cone should then be cleaned of all solvents, and the canal obturated using sealer in the usual way. As with all single-cone techniques, if the excess sealer resorbs in the apical tissue fluids, microleakage may allow the ingress of tissue fluids and failure of the stated criteria of obturation. Really, an attempt should always be made to improve the fit of a single cone with warm or cold lateral compaction of accessory points.
