The present study compared the ability of the
endodontic sealers AH Plus, Pulp Canal Sealer and EndoREZ to fill the root canal
system in association with gutta-percha.
mandibular premolars were accessed, prepared and divided into three groups of 30
teeth each, according to the sealer used to fill the canals: AH Plus, Pulp Canal
Sealer and EndoREZ. All the teeth were filled using the continuous wave of
condensation technique. The specimens were then decalcified, dehydrated,
rendered transparent, and analyzed by three independent evaluators with 8x
magnification. Chi-squared test (χ2, p < 0.05) was used to compare
the groups in relation to the totally filled, the partially filled and the non
filled ramifications. The same test was used to compare the directions of filled
ramifications and the number of ramifications among the three thirds of the
EndoREZ filled a significantly higher
number of ramifications than AH Plus and Pulp Canal Sealer (χ2, p <
0.05). All the groups showed higher number of totally filled ramifications than
partially filled and unfilled ramifications. The ramifications were more
frequently detected in the apical third, followed by medium and coronal thirds,
respectively (χ2, p < 0.05). The ramifications were more frequently
detected towards lingual direction (χ2, p < 0.05).
EndoREZ presented higher ability to fill
the root canal system in association with gutta-percha when compared to AH Plus
and Pulp Canal Sealer. The ramifications were more frequently detected in the
apical third, running in a lingual direction.
