يهدف هذا البحث إلى تقييم الفعالية المضادة للجراثيم لعدد من المواد المستخدمة كمضادات و سوائل إرواء في الأقنية العفنة و من ثم المقارنة بين فعالية كل من سوائل الإرواء و المواد المستخدمة كمضادات داخل الأقنية العفنة. بلغت عينة البحث 90 حالة عفنة لأسنان وحيدة الجذور قسمت العينة إلى ثلاث مجموعات متساوية طبقت على كل مجموعة مادة من هذه المواد (ماءات الكالسيوم مع الهيبوكلوريت , ماءات الكالسيوم مع اليودفورم و الكلور هكسيدين) ثم أجريت عمليات الزرع الجرثومي ( هوائي و لا هوائي ) و قيمت الحالات من ناحية نتائج الزرع الجرثومي . أظهرت الدراسة أن الكلور هكسيدين كمضاد إنتان أفضل و أكثر فعالية من ماءات الكالسيوم مع الهيبوكلوريت و من ماءات الكالسيوم مع اليودفورم.
This study aims to evaluat of the effect antibacterial for some materials which are used dressing and irrigating fluids in infected root canal then compare of the effectiveness of each of The irrigating fluids and materials used Dressing in infected root canal The sample of study was 90 cases a single infection root canal , were divided into three group and applied to the total of each such substance(calcium hydroxide with sodium hypochlorite ,calcium hydroxide with Iodoform, chx) and then conducted the transplant bacterial. The cases were evaluated in terms of results of bacterial culture. The study showed that chx best antidote infection of calcium hydroxide with sodium hypochlorite and calcium hydroxide with Iodoform

This In Vivo study aimed to compare the antibacterial activity of
alcoholic extract of propolis and Miswak with sodium hypochlorite and saline.
The study was performed on 40 infected single root canals for
patients of both sexes, regardless of gender or age.
Aim of study: to compare the ability of four restorative materials (MTA - Composite
- Zinc Phosphate - Glass Ionomer Cement) in coronal sealing of the endodontically treated
root canal orifice in extracted teeth.
Materials and Methods: 60 extracte
d teeth with single canal were chosen. X-Ray
Images were taken, then their crowns were cut off by using diamond disc, then the canals
were classically prepared, after that, they were filled with Zinc Oxide Eugenol Cement and
the gutta-percha cones using Lateral Condensation technique. They were left for (24) hours
in order to ensure the quite hardening of the filling material. After that, the filling material
was removed vertically by using an eraser tool up to a depth of (2) mm inside the root
canal. Then, the teeth were randomly divided into four groups, each contained (15) teeth
(n1=n2=n3=n4=15). The entry orifices of all the teeth were filled with one of the
restorative materials. The teeth were coated with Varnish except for 1 mm around orifices,
After then, they were immersed in Methylene Blue Dye of 2 % for five minutes. After that,
the teeth were washed under a stream of plentiful water and left to dry. Longitudinal
sections were made in the buccal lingual direction. Then the sections were examined under
the optical magnifier to measure the liner dye leakage using a millimeter ruler designed by
“AutoCAD 2013” Program.
The Rootcanal treatment is considered as the most accurate one
followed in (( dentistry )), which need a right diagnosis and exact
treatment steps to be performed completely for an excellent
prognosis treatments ended by along time –perfect success.
The aim of this study was evaluation the effective of chelating
solutions 17% EDTA, 0.2% Chitosan and 10% Sodium citrate by
comparing the concentrations of chelated calcium ions after
(1min-5min-24h) of application. The study was performed on 45
extracted single-rooted sound human. The sample was randomly
divided into groups (n=3), each group 15 teeth that depend on the
used solution.
Objective:This study evaluated the fluoride release of four dental restorative
materials for a period of 28 days.
Materials And Methods:A total of 10 specimens (4 * 2 * 2)mm3 for each of the four
materials were prepared following manufacturer’s in
structions and immersed
independently in 2 ml of distilled water which was changed every period for all the
specimens.
Results:The results demonstrated that the glass ionomer cements (Fuji IX GP and
VivaglassCem) release high fluoride compared with the compomer and composite resin,
but rapidly decreased after the third day and continued this releasing for a period of 28
days , also showed low fluoride release of composite resin and lacking entirely with the
passage of time.
Conclusions:The fluoride released by the glass ionomer cements (GICs) was found
to be highest during the first 24 h and decreased significantly over the 1st week with lower
levels obtained on the 28th day, thus demonstrating the phenomenon of “initial burst”.
The composite resin and compomer used in this study did not show this “initial
burst”.
