Root Canal Obturation Techniques: Lateral Compaction vs Warm Vertical Compaction
1.
2.
3. The tooth is asymptomatic.
The canal is dry
There is no sinus tract.
There is no foul odor.
A negative culture is obtained.
Criteria for root canal obturation
6. it has several disadvantages and cannot be
considered as one that seals canals completely.
the technique is simple,
7.
8. The master cone should need some force to be seated inside the canal & some
force is required to dislodge the master cone from the canal.

16. The advantage of the lateral compaction technique in comparison with the single-
cone technique
1. reduces the amount of sealer left in the canal,
2. the length control of the filling is quite good
3. no filling material is extruded beyond the foramen.
4. The seal is good in comparison with other techniques. .
The disadvantage of the lateral compaction method
root filling consists not of a homogeneous mass of root filling
material but rather of a large number of individual points tightly
pressed together and joined by the frictional grip of the cementing
substance
22. A distinct disadvantage is that the softening of the
gutta-percha may lead to overextension of root filling
material.
The advantage of warm lateral compaction is that it
leads to a homogeneous mass that, permitted
significantly less leakage than cold lateral compaction.
26. The advantage of the warm vertical compaction technique is that
it results in a homogeneous mass of guttapercha, well-adapted to
the canal wall, that requires a minimum of sealer.
• The disadvantage is that the technique almost
consistently leads to extrusion of filling material
30. Thermomechanical compaction
The advantage is that it is a very fast
technique leading to a compact mass of
gutta-percha that, in wide canals, resulted in
less Leakage than lateral compaction.
The disadvantage is that the technique
requires a lot of practice to get consistent
results.
31. Injection technique
The Obtura system uses a pressure syringe in which the gutta- percha is warmed to 200°C and
expressed into the canal through a needle as fine as 25 gauge (0.5 mm diameter). The gutta-
percha leaves the needle at approximately 70°C.

33. Advantages of the injection technique are similar to those of
warm vertical compaction. It also is useful in wide canals with
an apical stop and in cases of internal resorption

34. The disadvantage is the difficulty
of controlling the level of the root
filling, with a possible under- or
overfill as a result. Shrinkage of
the gutta-percha during cooling
may cause voids
40. The advantage of this technique is that, once the
cone is properly heated in the oven with this
system, the canal can be well obturated in all its
dimensions within a short time.
The advantage of this technique is that, once the

The disadvantage of the system is that, especially
in curved canals, there is a risk for gutta-percha to
be stripped off, thus, the core material will only
become cemented apically
