Abstract: الثلاسيميا نوع بيتا هو الاضطراب الاحاد اليين الاكثر شيوعا في الشرق الاوسط، والتي تتميز بشذوذ في تركيب سلاسل بيتا من خضاب الدم مما يؤد الى ظواهر متفاوتة تتراوح بين فقر الدم الشديد الى عدم وجود اعراض سريريا.اهداف الدراسة : تحديد مدى انتشار المضاعفات الفمو | Beta - thalassemia is the most common monogenic known disorder in the Middle East, characterized by anomalies in the synthesis of the beta chains of hemoglobin resulting in variable phenotypes ranging from severe anemia to clinically asymptomatic Individuals. Several immunological defects can be found in patients with beta - thalassemia major patients, among which circulating cytokines levels, impairment of neurophil, macrophage phagocytic and killing functions, this impairment may be due to iron over load.Aims of study : Aims of this study was to evaluate the prevalence of Orofacial complications in beta - thalassemia major patients, salivary flow rate, salivary levels of salivary immunoglobulin A, interleukin - 6 and tumor necrosis factor alpha and to evaluate correlations between salivary parameters (salivary immunoglobulin A, interleukin - 6, tumor necrosis factor alpha and salivary flow rate) in beta thalassemia major patients.Methods : Sixty subjects were participated in this study, they were divided into two groups, patients group composed of 30 patients with major beta - thalassemia, age rang (5 - 23), and 30 healthy looking subjects of both sexes as a control group, age rang (5 - 25). Data was collected using a special formula for general, medical and Orofacial examination sheet. Whole non - stimulated saliva was collected, measured and analyzed by enzyme linked immmunosorbent assay.Results : Most patients were in the first and second decade of life (90%), 20 (60%) were males and 10 (40%) were females with an age rage (5 - 23 years). The prevalence of Orofacial complications in beta - thalassemia major patients increased with age.The prevalence of orofacial complications in beta - thalassemia major patients were color change of oral mucosa (73.3%), rodent face (66.7%), maxillaryprotrusion (66.7%), saddle nose (63.3%), deep bite (26.7%)), open bite (13.3%) and spacing (10%).Regarding the salivary flow rate there was a statistically significant decrease in mean of salivary flow rate in patients group as compared with control group (P= 0.013).Laboratory investigations for salivary concentration of interleukin - 6, tumor necrosis factor alpha and salivary immunoglobulin A revealed highly significant to significantly in mean of these parameters in beta thalassemia major patients as compared with control group, interleukin - 6 (p=0.001), tumor necrosis factor alpha (p= 0.01) and salivary immunoglobulin A (p= 0.05) at P value ? 0.05.Conclusions : Beta - thalassemia major patients have specific Orofacial complications and a particular salivary cytokines compared to normal individuals.

Abstract: الاتجاه الجديد للغرسات هوايجاد المواد التي تسرع عملية بناء العظم في السطح البيني للعظم والغرسه وتحسين الاندماج العظمي من اجل توفير التحميل الفوري والمباشر بعد وضع الغرسات وتقليص فترة الانتظار التي تكون مزعجه وغير مريحه للمرضى.الاهداف.تقييم تاثير طلاء ال | Introduction : The new trend of implants is to find materials which accelerate bone formation in bone implant interface and improve osseointegration to provide immediate or early loading after placement in addition to eliminate the waiting period which is usually uncomfortable and disturbs patients. Aim of study : To evaluate the effect of plasma nitride treatment of screw shaped commercially pure titanium dental implant on bond strength at bone implant interface by torque removal test and histomorphometric analysis after 2 and 6 weeks in comparison to non treated one.Materials and methods : Commercial pure titanium plates and screws were plasma nitrided for 10h using glow plasma nitride apparatus. X - ray diffraction (XRD) analysis , scanning electron microscope examination were carried out on the nitride surfaces of the plates ,contact angle measurement (Wettability) was done by applying drop of saline and blood on the nitrided surface and compared to control. The femur of 10 white New Zealand rabbits were chosen as implantation sites. The femur of each rabbit received two screws, one plasma nitride treated and one non treated and a total of 40 screws were implanted. Torque removal test was performed(by digital torque meter) to measure bond strength between implant and bone, after 2 and 6 weeks healing periods. For each period of time 18 screws were tested for the torque required to remove the implant from the bone and 2 screws were kept for histological examination. Results : The results revealed that the mean removal torque values for the plasma nitride treated implants was significantly higher than the non treated implants and over the two periods of time. There was an increase in the bond strength (torque value) of bone - implant interface with time. The torque removal force for plasma nitride implants after 2 and 6 weeks was (30.22, 59.56 N.cm ,respectively) and for non treated implants after 2 and 6 weeks were ( 23.61,56.11N.cm, respectively) and new bone formation ratio for plasma nitride treated implants after 2 and 6 weeks(3.36, 4.72 , respectively) and for non treated after 2 and 6 weeks(1.56, 3.04, respectively). Conclusion : Plasma nitriding of Cp Ti screws significantly increased the torque removal value and new bone formation ratio at 2 and 6 weeks compared with the non treated implant.Dental implant, Osseointegration, Digital torque meter

Abstract: Background : University dental students perceived a higher level of stress prior to each examation especially the final. Therefore, there is a need for a useful noninvasive biomarker for measuring acute stress in those students. Many studies considered salivary alpha - amylase as a stress biomarker that is most often used in conjunction with cortisol. Understanding of the exact association between these two salivary stress markers are poorly established. Using a Helkimo anamnestic and clinical dysfunction scoring index for temporomandibular disorders can give a better insight about the association between these markers and temporomandibular joint disorders.The aims of study : was to evaluate the levels of salivary alpha - amylase and salivary cortisol in stressed students with temporomandibular joint disorders and the differences between these markers in relation to temporomandibular joint disorders students. This might give a better understanding to the role of psychological stress as an etiological factors for developing temporomandibular joint problems.Subjects, materials and methods : A total eighty (60 study and 20 control) participants aged between 20 and 24 years, were recruited for this study. The participants were final year undergraduate Baghdad university dental students who were examined and gave saliva samples before their final academic examination. Those with temporomandibular joint disorders problems were exposed to psychological stress and included on the study. While, those who were taking corticosteroids or hormone supplementation including oral contraceptives, or having history of head injury, orthodontic treatment, occlusal disharmonies and muscle tenderness due to systemic diseases as fibromyalgia, or having more than 2 missing posterior teeth were excluded. Salivary assay kits (alpha - amylase and cortisol) were used to measure those variables and a Helkimo anamnestic and clinical dysfunction scoring for temporomandibular joint disorders were utilized in this study.Results : There is statistically a highly significant difference of the salivary cortisol and salivary alpha - amylase in the patient group( stress with temporomandibular joint disorders) and control group. The absence of correlation between these salivary markers was founded. Correlation analysis of salivary cortisol with Helkimo anamnestic and clinical dysfunction score shows positive association expressed by significant probability of error (p) value while for salivary alpha - amylase there is no association.Conclusion : This study demonstrates that salivary alpha amylase can be used as a stress biomarker in conjunction with cortisol to assess temporomandibular joint problems due to psychological stress in university students.

Abstract: Thalassemia is a hereditary anemia resulting from defects in hemoglobin production. Beta Thalassemia, which is caused by a decrease in the production of beta globin chains, affects multiple organs and is ssociated with considerable morbidity and mortality. Aims of the study : The aims of this study were to study the oro - facial manifestations in beta thalassemia major patients and evaluation of the oxidative stress status in serum and saliva represented by malondialdehyde as xidative stress indicator and also assessment of serum and saliva antioxidants which are ceruloplasmin and uric acid in beta thalassemic patients with and without periodontitis and compared that with the healthy individuals in addition to investigate the relation between the clinical findings and laboratory investigations.Methods : Eighty seven (87) subjects were consented and contributed in this study, twenty eight (28) thalassemic patients with periodontitis, thirty (30) thalassemic patients without periodontitis and twenty nine (29) healthy subjects that were age matched with the patients. Oral examination has been done for each subject. Serum and saliva sample have been taken from each subject for analysis, to study malondialdehyde as oxidative stress and antioxidants ceruloplasmin and uric acid.Results : Malocclusion was the most common prevalent oro - facial manifestations (60%), followed by rodent face (35%), brown pigmentation of oral mucosa (23%) and incompetent lip (8%). The mean serum and saliva malondialdehyde were significantly higher in thalassemic patients with periodontitis than that in thalassemic patients without periodontitis and healthy subjects (p<0.001), while the mean serum and saliva ceruloplasmin were significantly higher in control group than that in other study groups (p<0.001). The mean serum uric acid was significantly higher in thalassemic patients without periodontitis than that in thalassemic patients with periodontitis and healthy subjects (p<0.001) and the mean saliva uric acid was significantly higher in thalassemic patients without periodontitis (p<0.05) compaired with thalassemic patients with periodontitis and healthy subjects. The results of this study showed that there were no significant correlation between serum and saliva malondialdehyde in any of study groups, while there was a positive significant linear correlation between serum and saliva ceruloplasmin in thalassemic patients with periodontitis (p<0.05), a negative significant linear correlation in healthy subjects (p<0.05) , a positive significant linear correlation in thalassemic patients without periodontitis (p<0.001). The results showed that there was a positive significant linear correlation between serum and saliva uric acid in thalassemic patients with periodontitis (p<0.05), a positive significant correlation in thalassemic patients without periodontitis (p<0.001) and no significant correlation between serum and saliva in healthy subjects. On the other hand there were no significant correlation between serum and saliva (malondialdehyde, ceruloplasmin and uric acid) and clinical attachment loss (p>0.05), except a positive significant linear correlation between clinical attachment loss and salivamalondialdehyde (p<0.05) was found. Conclusions : Malocclusion was the most prevalent oro - facial manifestations of beta thalassemia major patients. Oxidative stress play a significant role in the pathogenesis of beta thalassemia ,which was the main cause of red blood cells destruction represented by significant elevation of serum and saliva malondialdehyde and significant reduction of ceruloplasmin. Also oxidative stress remain contributing factor in periodontal tissue destruction, which was appeared as a significant increased level of saliva malondialdehyde and decreased saliva ceruloplasmin in patients with periodontitis and there was a significant correlation between saliva malondialdehyde and clinical attachment loss

Abstract: Petroleum is perhaps the most important substance consumed in modern society. Petroleum is unique and s a complex mixture of thousands of compounds. Oil refinery workers are continuously exposed to numerous hazardous materials and working conditions that place them at continuous risk of injury and death.Petroleum contains the heavy metals as a natural constituent or as additives. The main threats to human health from heavy metals are associated with exposure to lead, cadmium, mercury and arsenic. Several carcinogenic metals such as arsenic, cobalt, chromium, lead, mercury, and nickel induce redox reactions in living systems. These metals induce the production of reactive oxygen species in both in vivo and in vitro systems. These radicals have rendered oxidative damage to deoxyribonucleic acid, proteins, and lipids. Secretory immunoglobulin A is the main immunoglobulin found in mucous secretions from the tear glands, salivary glands, mammary glands, the respiratory system, the genito - urinary tract, and the gastrointestinal tract.Aims of the study Assessment of the salivary levels of heavy metals among the workers of Al - Daura oil refinery, assessment of the oxidative status in the oral cavity of the workers by measurement of Malondialdehyde and Superoxide dismutase markers,assessment of the oral immunological activity by measurement of secretory immunoglobulin A level in saliva and Assessment of the oral findings among the workers.Subjects, Materials and Methods This study was done in Al - Daura oil refinery, samples consist of 60 workers involved in refining processes as study group subdivided into three subgroups which represent the different sections in the refinery and 20 subjects not involved in refining processes as control group. Oral examination and saliva collection was done to assess the oral findings and measure the level of heavy metals (lead and cadmium), oxidative status (Malondialdehyde and Superoxide dismutase) and secretory IgA.Results The mean of salivary lead and cadmium was higher in study group (6.34 ?g/dl and 0.56 ?g/l respectively) than that of control group (3.3?g/dl and 0.34 ?g/l respectively) with highly significant difference (p
