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: Background : Bones are rigid organs that constitute part of the endoskeleton of vertebrates. They support and protect the various organs of the body, produce red and white blood cells and store minerals. Bone tissue has been shown to contain numerous cell - to - cell signaling peptides called growth factors. These growth factors are thought to have important regulating effects for bone remodeling and bone healing. Several growth factors are expressed during fracture repair. of these, vascular endothelial growth factor (VEGF), is of particular interest because of its ability to induce neovascularization (angiogenesis). The responses to exogenous VEGF observed that a slow - release formulation of VEGF, applied locally at the site of bone damage, may prove to be an effective therapy to promote human bone repair. N - acetyl glucosamine is a monosaccharide, which are the derivatives of carbohydrates, it helps the body in making several other chemical agents which are used in the formation of bones, muscles and cartilages.N - acetylglucosamine is very effective in providing support for the skeletal system of the humans, and may provide strength to the ligaments and joints, and the skin remains fresh and glowing. Aims of study1. To identify role of local exogenous application of vascular endothelial growth factor and application of N - acetyl - D glucose amine as a biomaterial in bone healing.2. To analyze the expression of Vascular endothelial growth factor, tissue non specific ALP and bone matrix protein (collagen - 1) by immunohistochemistry in created bone defect after application with different biomaterials in a rat model. Materials and MethodsIn this experimental study fifty four male Albino rats, weighting (300 - 400) gram, aged (6 - 8) months were used and maintained under control conditions of temperature, drinking and food consumption. The animals were subjected for a surgical operation of medial sides of both tibial bone ( right side was considered as experimental site ,while left be the control one). The animals were divided into following groups according to the applicable growth factors.A. Contol group the bone defect treated with 1?m of normal saline and its number represented the all number of the following experimental groups as the left side of each animal considered to be the control.B. Experimental group includes ? Group I contains (18) rats, the bone defect treated with 1?ml of Vascular endothelial growth factor. ? Group II contains (18) rats the bone defect treated with 1?ml of Nacetyl D - glucosamine.? Group III contains (18) rats, the bone defect treated with 1?m combination of (VEGF& N - acetyl D - glucosamine).Every single group composed of 18 rats that studied in three periods 3,7,10 days (6 rats for each period). Histologic and immunohistochemical evaluation for VEGF, alkaline phosphatase and collagen type 1 were carried for all animals.Results : A. For Histological findings An early apposition of osteoid tissue was detected in VEGF group. Osteoblast, osteocyte and osteoclast cells count were demonstrated to be with high mean value in VEGF group followed by N - acetyl Dglucosamine group in periods 3,7,10 days post operative of bone defect.Inflammatory phase as first step in bone healing was detected in all study groups at 3 day, and combination group records highest value in the mean of inflammatory cell count in comparisum to others. Finally thestudy demonstrated that exogenous VEGF/ N - acetyl D - glucosamine has a direct effect on osteoblastic activity.B. For Immunohistochemical findings The present result showed positive expression of VEGF by bone marrow stromal cells, adipocytes, mesenchymal stem cells, precursor endothelial cells, and bone cells include osteoblasts and active osteocytes in different periods in all groups but in different score. Therefore, our primarily data provide evidence that VEGF activity is essential for appropriate bone formation and mineralization in response to injury. At day 3, bone marrow stromal cells in combination group records highVEGF expression, VEGF group is the second. At 7 and 10 day VEGF group records a highest VEGF expression in comparisum to other groups. The data showed a high expression for ALP during the formative stages of bone in all groups except combination group shows the lowest count for positive cells that expressed ALP.the present results showed that at day 3, bone marrow stromal cells in VEGF and N - acetyl D - glucosamine group records high collagen type I expression. Conclusion : the study demonstrated that low application of VEGF / Nacetyl D - glucosamine could be an effective therapeutic for bone injuries, these data are promising for a possible future clinical usage.

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
