The goal of
successful endodontic treatment is to complete the obturation of the root canal
with an inert filling material and hermetic apical seal also one of the
criteria believed to be important the integrity of the root canal filling in
the apical few millimetres. A solid core cemented in the root canal with a
sealer is the most use obturation methods (Gencoglu, et al, 2002).?
studies the percentage of gutta-percha filled area (PGP) has been measured. The
better quality of obturation have smaller area of sealer and voids and the PGP
is higher. When the PGP score is lower reveal a problem in filling or anal
occupied by debris. The PGP score lower in oval canal due to difficult to place
secondary cones in the wing and irregular shape of the wing reveal a problem
when using the cold lateral compaction technique (Sluis, et al, 2005).
condensation technique resulted in virtually of gaps and high amounts of sealer
on the root surface, unlike the thermafil obturation technique. With the
lateral condensation technique tubule sealer penetration occurred, it’s deeper
especially in the mid and apical zones (Guigand, et al, 2005).
studies the comparison between the thermoplasticized gutta-percha and cold
lateral condensation in the quality of root fillings has been evaluated, with
differing conclusions. On radiographs, results in the apical third for both
methods were similar, but generally better adaptation than lateral condensation
showed with the thermafil obturation technique. Scanning electron microscopic
observations for Ultrafil, Thermafil and lateral condensation showed better
dentinal wall adaptation in roots obturated with thermoplasticized gutta-percha
than in laterally condensed root canal fillings, regardless of the presence or
absence of a smear layer (Kqiku, et al, 2006).
The total obturation of the root canal
space is the final objective of endodontic procedures. To achieve total root
canal obturation many root canal filling techniques have been developed. Most
of the currently employed techniques use either a solid core and a cementing
substance, or a plastic material which can be adapted more or less to the shape
of the root canal system (Schilder,2006).
showed the lowest gaps and voids at the apical third where Gutta-percha
exhibited the lowest percentage of voids and gaps in the root sections. This
also can be attributed to the filling technique, because the manufacturers of
GuttaFlow recommend that it is dispensed first in the apical part of the root
canal, and then a master gutta-percha cone is placed. This ensures the least
amount of voids and gaps in the apical third (Hammad, et al, 2009).
