These factors might predispose postoperative pain need to be avoided; when postoperative pain is suspected it should be controlled carefully. Methods: 42 patients were selected and Root canal treatment was performed in a single visit. Straight-line access cavity was made, working length was determined, root canals prepared manually utilizing step-back technique; Irrigation was performed between each file with the use of 2.5% NaOCl solution. Root canals obturation was performed utilizing cold lateral compaction technique. Postoperative pain was assessed using the Visual Analogue Scale (VAS) on the 1 st , 2 nd , and 7 th days following the treatment. Data were analyzed using Mann-Whitney and Kruskal-Wallis H tests and the significance was set at P < 0.05. Results: There was a significant difference between male (48%) and female (52%) patients in postoperative pain values at study intervals, while other studied variables had an insignificant role in postoperative pain induction or aggravation. Conclusion: Non-surgical root canal treatment could be safely applied with low potentials of postoperative pain regarding the studied variables, except patient gender that might be considered as a predisposing factor for postoperative pain.

Material and methods: One-hundred sixty eight human maxillary central incisors were selected for the study. Teeth were cut apically 12 mm below and coronally 2 mm above the cementoenamel junction. Canals were instrumented up to instrument F5 (ProTaper Universal, Dentsply Maillefer, Ballaigues, Switzerland), then Peeso drills (Mani, Tochigi, Japan) were used from No. 1 up to No. 6 , passing 1 mm beyond the apical foramen to obtain larger root canals. Between every 2 consecutive instruments 2 mL of 2.5% sodium hypochlorite (NaOCl) used for canals irrigation , final flush using 5 mL of 2.5% NaOCl and 5 mL of 17% ethylene-diamine-tetra-acetic acid (EDTA, Sigma) followed by 10 mL of distilled water. Samples were randomly divided according to the type of the ICM used inside the canal into 4 equal groups (n = 42); Group 1: Double antibiotic past(DAP) paste: 1:1 mixture of ciprofloxacin (Cipro 500 mg, Schering Plough, Kenilworth, NJ, USA) and metronidazole (Flagyl 500 mg, Sanofi-Aventis, Tours, France), Group 2: Bioactive glass powders (BAG S53P4) of 60 mol% SiO 2 , 12 mol% P 2 O 5 and 28 mol% CaO composition were prepared through sol gel processing route, all reagents were purchased from Sigma-Aldrich(Dorset, UK). Group 3: Non-setting Calcium hydroxide (CH) (Merk, Germany) was used, and finally, Group 4(Control): where no ICM was applied. Samples were kept in saline solution for either 2, 4, and 12 weeks, randomly selected samples from each group n=14 at each interval where intracanal medication removed, half of them n=7 were subjected to dentin Vickers microhardness test, in remaining half n=7 MTA (ProRoot, Dentsply Tulsa Dental, Tulsa, OK) placed 4 mm deep into the coronal third of the roots having a 4 mm-long chamber, samples were stored for a week at 37 °C at 100 % humidity to allow the complete setting of MTA, then push-out test was used to measure the dislocation resistance DR of MTA. Collected data were analyzed using a two-way ANOVA followed by Bonferroni's post-hoc test was used for pair-wise comparisons (P ≤ 0.05).

Materials and Methods: In this study thirty brand-new endodontic files having tip size 25/0.6 of the following systems were used: Neolix (Neolix, Châtres-la-Foret, France), One Curve (Micro mega, France) and AF™ Blue S ONE One-File System (Fanta, USA). These files were equally divided into three groups (n=10). Ninety simulated curved canals (Endo Training Block-L; Dentsply Maillefer, Ballaigues, Switzerland) with curvature of 45o±10o, with 0.02taper, 0.15 mm apical diameter, and 16 mm length were used.

Twenty freshly extracted human anterior teeth with single root canal were collected. The crowns were sectioned at the cemento-enamel junction, and working length was measured. These samples were randomly divided into four groups of five samples each. In each group, 2 ml of 3 % sodium hypochlorite solution was used with first instrument. The groupings were as follows. Group 1: 2 ml of 17% EDTA solution and 2 ml of 3% NaOCl were used alternatively each time a new file was employed. This group was prepared with Mtwo rotary files. Group 2: The samples in this group was prepared with Mtwo rotary files. EDTA gel (19%) was used and the samples were irrigated with 2 ml of 3% NaOCl. NaOCl and EDTA gel were used alternatively. Group 3: Five samples were prepared with Protaper file. Irrigation regime was the same as in Group 1. Group 4: Five samples were prepared with Protaper files and irrigation regime was the same as in Group 2. SEM study was done and the collected data were submitted for statistical analysis. There was no statistically significant difference with the varied instruments used (Mtwo and Protaper files), and 17% EDTA solution and 19% EDTA gel. Both the NITI instruments produced a similar dentin surface on root canal wall when used with EDTA gel and EDTA solution.

Material and Methods: Forty-five freshly extracted human single-rooted maxillary incisors were divided into 3 groups (n=15) then instrumented using Protaper Next, Twisted files, and Reciproc. The extruded debris were collected in a pre-weighed Eppendorf tubes. The tubes were stored in an incubator at 70 °C for 2 days before weighing the dry debris using analytical balance. The debris weight was determined by subtracting the initial weight from the final weight. Root samples were splitted longitudinally into two halves by making grooves then root halves (cervical, middle and apical) thirds were examined using Environmental Scanning Electron Microscope ESEM (FEI Quanta 250 FEG, Berlin, Germany) at ×1500 magnification. All the data were subjected to statistical analysis using Chi-squared, Fisher`s Extract. Results: The three tested rotary nickel titanium files produced comparable amount of debris extrusion and smear layer patterns covering the root canal dentin walls. Apical third showed the heaviest accumulation of smear layer.

Double rooted anterior teeth are rarely reported. This case report aim was to represent management of a case has mandibular canine with two root canals within two separate roots. Endodontic treatment of tooth #33 with such morphology was performed in a 41-year-old woman. Therefore, clinicians must always suspect anatomical varieties and do not ignore anatomical variations even if recorded low prevalence, use all the available tools to diagnose, carefully examine the initial radiograph which is extremely important for these cases management.

Materials and Methods: In this study thirty brand-new endodontic files having tip size 25/0.6 of the following systems were used: Neolix (Neolix, Châtres-la-Forêt, France), One Curve (Micro mega, France) and AF™ Blue S ONE One-File System (Fanta, USA). These files were equally divided into three groups (n=10). Ninety simulated curved canals (Endo Training Block-L; Dentsply Maillefer, Ballaigues, Switzerland) with curvature of 45º±10º, with 0.02taper, 0.15 mm apical diameter, and 16 mm length were used. File`s surfaces examined by Environmental Scanning Electron Microscope ESEM (FEI Quanta 250 FEG, Berlin, Germany) at 500X magnification before use. Cutting blade (active part) images been processed and their micrographs were analyzed at the tip, 2 and 4 mm short of its cutting tip. The Nickel (Ni) and Titanium (Ti) average contents (wt %) on the instrument`s surface were also analyzed before their use, using an Energy Dispersive Spectrometer Device (EDAX-AMETEK, Inc., Mahwah, NJ, USA). All instruments prepared using electric motor (Motor X-Smart Plus, Dentsply/Maillefer), following manufacturer`s instructions for each system. Each used file prepared three simulated canals, after each canal instrumentation, each file was removed for cleaning its flutes gently with sterile gauze, and for canal irrigation using with 2 mL/ 2.5% NaOCl irrigating solution. After the first and third instrumentation performed; files were cleaned, dried, stored and sent to SEM equipment for post-instrumentation files surface's topography analysis and chemical composition of the NiTi content (wt %) according to the previously described pre-instrumentation analysis protocol. SEM micrographs recorded on a CD-ROM and projected for three blinded examiners'. They were given a spreadsheet including the instrument data (number, the location to be evaluated; tip, 0-2mm or 2-4mm from the tip) and the side of the instrument (detail facing up or down), and the criteria of defects and deformation assessment namely (irregular edges, grooves, micro-cavities and burrs).Data were recorded and statistically analyzed.
