واحدة من أهداف المعالجة اللبية هو تأمين ختم محكم ثلاثي الأبعاد للنظام القنيوي لمنع دخول العضويات و منتجاتها عبر كلا الطريقين التاجي و الذروي. إن الكوتابركا هي المادة الأكثر استخداماً لحشو الأقنية الجذرية و بالرغم من خواصها العديدة مثل التقبل الحيوي و قابلية التليين بالحرارة فإن لها محدودية مهمة و هي: عدم الارتباط إلى جدران القناة.
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 canals. It has limited importance in spite of many specifications as lack of the link to the ridge canal.

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.
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.
A comparative study was conducted between GIC and Biodentine
Cements by assessing their solubility, their effect on pH, their ability to
absorb water, and calcium release in the same laboratory conditions.
Aim: The aim of this study was to detect the effect of dressing period of calcium
hydroxide medicament on the apical marginal leakage after obturation of root canal
system.
Materials and Methods: 80 freshly extracted single rooted human teeth were
selected ,all the root canals were hand-instrumented. They were randomly divided into four
groups of 20 teeth each. Group A has no intracanal medicament , groups (B,C,D) were
dressed with Ca(OH)2 paste for a different periods of time (7,14,30) days respectively,
groups (B,C,D) were divided into subgroups of 10 teeth according to removing of dressing
. The removal of ca(OH)2was done by two ways, 1- By irrigating with distilled water and
drying with paper points . 2- Size 40 k-file was used in slightly filing motion up to the
working length then irrigated with distilled water and drying with paper points. After that
all groups were obturated with lateral compaction technique using gutta-percha points and
zinc oxide-eugenol cement. Then the access was sealed with GIC cement. The teeth were
immersed into 2% mythylene blue solution ,The specimens were placed in an incubator at
37 C ,with moisture at 100%, for 7 days .After that the roots were sectioned
longitudinally and examined with stereomicroscope and liner leakage was measured.
This study aims to determine the direct role
of some factors that contribute to improve the prognosis of the
Cervical and Furcation Perforations throughout application of
bioactive materials using non surgical methods.
