The Electrophoretic Deposition of Nano Al2O3 and AgNO3 on CpTi Dental Implant (An in vitro and in vivo study)
...Show More Authors

Background: Even the wide use of dental implants, still there is a proportion of implants are failed due to infection. Much considerable attention has been paid to modify the implant surface. Coating of dental implant with a biocomposite material of suitable properties can improve osseointegration. And this is the main concern of this study. The aim of present study was to evaluate the use of a biocomposite coating of dental implant with (ceramic nano Al2O3 and metalic AgNo3) on the bond strength at bone – implant interface and tissue reaction. Materials and methods: A total number of forty-eight screws, CpTi dental implant used in this study. Half of these screws were coated with a biocomposite material of nano (Al2O3and AgNo3), this was done by using electrophoretic deposition method (EFD). In invitro part of the study, analysis of the coated surface was done using: X ray diffraction (XRD), atomic force microscope (AFM), Energy Dispersive X-ray spectroscopy (EDX), Optical microscopy and Scanning electron microscope (SEM). In invivo part of study, 10 white male New Zealand rabbits were used, and a screw type of dental implant [uncoated and coated with nano (Al2O3and AgNo3)] were implanted in each tibia of rabbit. Then biomechanical and Histological test were performed after 2 and 4 weeks healing intervals. Results: The results of biomechanical test showed a higher torque mean values of (M+SD):(14.91N.cm+2.7)and (22.5 N.cm +5.31) after 2 and 4 weeks respectively. In histological examination of coated screws at 2 weeks, there isa bone trabeculae occupies a base of implant bed with osteoblast andosteocyte. At 4 weeks, there is a progress in the healing process around dental implant, and this includes: -new bone with haversian canals, osteoblast and osteocyte. Conclusion: Biocomposite coating of dental implant with Alumina and silver nitrate can be made by electrophoretic deposition method (EPD), and a multifunctional surface has been created. Keywords: Electrophoretic Deposition, alumina, screw Dental Implants, torque.

   In this study Isolated Pathogenic bacteria which causes Conjunctivitis in Children with ages between less than 3 year to17 years, admitted to Ibn Al-Haitham Eye Specialist Hospital. 102 cases were collected which include 69 Male Formed (68%) and 33 Female Formed (32%). The result of the recent study shows that the highest percentage of Male was 21% for 1113year ages and the lowest percentage was 3% for less than 3 year to 5 year ages. In Female the highest percentage was 15% for 9-11year ages and the lowest percentage was 1% for 1517year ages. In this study fifty tow isolates were identified, Gram Positive Bacteria were Predominant compared with Gram Negative Bacteria. With 32 isolates which formed (62%) whereas the number o

The in-vitro development of novel enzyme-based chemo-mechanical caries removal agents
...Show More Authors

Objectives Bromelain is a potent proteolytic enzyme that has a unique functionality makes it valuable for various therapeutic purposes. This study aimed to develop three novel formulations based on bromelain to be used as chemomechanical caries removal agents. Methods The novel agents were prepared using different concentrations of bromelain (10–40 wt. %), with and without 0.1–0.3 wt. % chloramine T or 0.5–1.5 wt. % chlorhexidine (CHX). Based on the enzymatic activity test, three formulations were selected; 30 % bromelain (F1), 30 % bromelain-0.1 % chloramine (F2) and 30 % bromelain-1.5 % CHX (F3). The assessments included molecular docking, Fourier-transform infrared spectroscopy (FTIR), viscosity and pH measurements. The efficiency

The Psychic Experience and its Effects on the Creative Process: A Study in Selected Poems By Allen Ginsberg and David Gascoyne
...Show More Authors

Evidences indicate that human beings were preoccupied with extreme forms of mental and psychic experiences long before they were recorded in literature. Greek myths and legends appear to include symbolizations of delusions, mania, and other bizarre forms of thought and behaviuor. The figure of the mad man or woman is analogous to the wild man, or the imaginary being who appears in various forms throughout western literature and art. Various studies refer to the notion of the wild man as a response to a persistent psychological urge. This urge gives an external expression and a valid form to the impulses of reckless physical self-assertion which is believed to be hidden in all of us, but is normally kept under control. Such impulses were exp

Comparative Assessment of In Vitro Effect of Three Fluoride Releasing Agents on Enamel Demineralization around Orthodontic Brackets
...Show More Authors

Background: White spot lesion considered as irreversible tooth demineralization presenting challenge to orthodontists during treatment schedules, fluoride was the most successfully used measure to overcome this challenge. Materials and method: A total of forty sound human permanent premolars were used in the present study and categorized into four groups, in one group the teeth were bonded with stainless steel brackets using Resin-modified glass ionomer cement (RMGIC) and the other three groups the teeth were bonded with light cured composite Resilience® (Ortho technology Co., USA). Group A; Acidulated phosphate fluoride (APF) topical gel (Mfg by DEEPAK PRODUCTS, INC, USA), fluoride ion 1.23% applied on examine area for four minute. Gro

      That corruption with all its forms,  has prevailed over the whole world, but  with  different degrees relaying on the one who leads these countries of rulers, followers and officials who have been deemed  the main reason for that corruption, but if these  rulers  were righteous, These countries would have blessed and elevated and were corrupt unjust tyrants who were the disaster that befell the chiefs of those countries  with ruin, misery, and backwardness. This is what we sought to prove and clarify by considering the verses of the Holy Qur’an in respect with this topic. The research includes an introduction, two topics, and a conclusion.

The planning for the formation of administrative policies and guidance through leadership are important things for managing administrative processes and sporting activities. As both contribute in the stability of the administrative conditions, and their development in the sport federations, whether they both were attentive about team and individual Olympic Games. The two researchers observe that, there is a variation in the correct way of application. Particularly in the formulation of administrative policies and leadership describing it as, modern management standards for both team and individual Olympic Games in the Iraqi National Olympic Committee. That led to cause a misconception and lack of clarity for some administrators of those uni

Effect of water absorption on some mechanical and physical properties of epoxy/polyurethane blend reinforced with nano silica powder
...Show More Authors

The aim of this work is to evaluate some mechanical and physical
properties (i.e. the impact strength, hardness, flexural strength,
thermal conductivity and diffusion coefficient) of
(epoxy/polyurethane) blend reinforced with nano silica powder (2%
wt.). Hand lay-up technique was used to manufacture the composite
and a magnetic stirrer for blending the components. Results showed
that water had affected the bending flexural strength and hardness,
while impact strength increased and thermal conductivity decreased.
In addition to the above mentioned tests, the diffusion coefficient
was calculated using Fick’s 2nd law.
