يعد الختم الذُّروي من أهم أسباب نجاح المعالجة اللبية، لذا هدفت هذه الدراسة إلى مقارنة جودة الختم الذروي لمادتي AH Plus و GuttaFlow عند تطبيقهما بتقنتي حشو مختلفتين.
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.

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.
One aim of the root canal treatment is providing compact
three dimensional seal for the canal system to prevent germs
enter and its products across both the apical and coronal
ways.
Gutta-Percha is the most use material to fill the radicalism
ca
nals. It has limited importance in spite of many
specifications as lack of the link to the ridge canal.
The apical seal, which is achieved by application of a retrograde
filling material, is considered one of the importan t elements in healing of the periapical lesions after apicectomy operations.The aim of this study was to compare the apical sealing ability of amalgam, MTA,and Bioaggregate when used as retrograde filling materials.
Aim of Study: The antimicrobial intracanal medication was used widely, and the most common was calcium hydroxide dressing, which must be removed from the root canal before obturation, hence this study aimed to comparative efficacy of EndoVac and Navi
Tip 30 G irrigation Needles with Naocl and CHX 2% in removing calcium hydroxide dressing from the apical third of root canal. Materials &Methods: Forty single root and canal teeth were decoronated to the length of 16 mm. Each root was prepared to the apical foramen using ProTaper Universal Hand System to size 40. Each tooth was embedded in silicone putty to create a set matrix, which allowed reassembly of the tooth for irrigation tests after splitting longitudinally. Then each tooth was split into two halves and an artificial groove (L:4, W:0,2 , D:0,5 ) was cut in one half of the root canal wall 1 mm from the apex ,which was then filled with a Ca(OH)2 paste. Digital images were taken before reassembling under stereomicroscope X40. Subsequently the two halves of roots were reassemble with wax , and remounted in their silicone matrixes, then divided into 2 groups.
