Aim: to compare the apical sealing ability of three root canal sealers in human
extracted teeth using dye penetration.
Materials and Methods: thirty extracted human maxillary teeth were instrumented
1mm short of the anatomical apex and randomly as
signed to three groups (n=10),
according to the root canal sealer used for obturation. The teeth were divided into three
experimental groups and obturated by cold lateral compaction of gutta-percha and one of
the following sealers: group I, Zinc oxide and Eugenol sealer; group II, Adseal; group III,
Apexit plus.The teeth were covered with nail varnish to within 2-3mm of the apical
foramen and immersed in 2% methylene blue for 24 hours.After this period, the teeth were
washed and cut longitudinally for apical leakage measurement inside the canal.
Results: Statistical evaluation of the results showed no significant difference in the
leakage between Adseal and Apexit plus (P =0.99). Leakage with ZOE was significantly
lesser than Adseal (P=0.004) andApexit Plus (P=0.003).
Conclusions:under the condition of this study, it can be concluded that ZOE presents
lower apical leakage than Adseal and Apexit plus, and there was no significant difference
in leakage between Adseal and Apexit plus.
Objective: the Purpose of this study was to evaluate in vitro the
apical microleakage of methacrylate risen-based sealer (EndoREZ )
after root canal irrigation with sodium hypochlorite or chlorhexidine
digluconate.
A good apical sealing is considered the key of the successful endodontic
treatments. The aim of this study was to compare the apical seal of GuttaFlow and AH Plus using single
cone and lateral condensation technique.
The filling material bonding to the wall of the root canal is so important with regard to decreasing the apical microscopic leakage. The aim of this study is to assess the ability of new resin root canal filling
materiales (Resilon) in bonding to th
e canal internal wall, bond strength, and to determined the nature of
bond failure, and compare this with two kinds of traditional root canal filling materials.
