Abstract: Background: Corona virus disease (COVID-19) manifested as acute respiratory distress syn-drome affected millions of people worldwide. Dentists are at increased risk of acquir-ing occupational infections. The infection susceptibility is linked with the both Anti-gen blood grouping system (ABO) and the alpha (1,2) fucosyl transferase (FUT2) se-cretor. Sudden onset of anosmia and/or ageusia symptoms could be enough to isolate patients and vaccinated participants even without doing the COVID-19 test. This study aimed to assess the changes in the chemical sense by one of objective methods the Connecticut Chemosensory Clinical Research Center Test (CCCRC). Assessed post-COVID Immuno-globulin A and G immunity, quantification of salivary biomarkers for prognostication, and immune surveillance. to find any association between specific ABO blood groups and FUT2 secretor status and COVID-19 in a sample of Iraqi den-tists. Methodology: For each 133 participants, a questionnaire including demography, COVID-19 status, blood grouping, Rhesus factor, with chemo sensitive symptoms was recorded using n-butyl alcohol and environmentally realistic odorants and calculated in a modi-fied way for the detection of olfactory function. The gustatory test scoring was done using the four standard primary tastes. A cross-sectional study was done on 91 out of 133 working Iraqi dentists from June to August 2022. The dual IgG and IgA for both spike and Nucleocapsid proteins (s1 & n) specific to COVID-19 were measured by En-zyme linked immunosorbent assay (ELISA)-specific kits from serum and saliva. For randomly selected 36 out of 91 participants Cluster of Differentiation 4 (CD4) and subtypes T helper 1 and T helper 2 were counted by flow cytometry from fresh whole peripheral blood. The DNA was extracted from salivary leukocytes for all study partic-ipants. Molecular detection of the FUT2 gene by real-time Polymerase Chain Reac-tion and the data were sequenced and the phylogenetic tree was drawn for randomly selected 20 participants. Results: participants were more commonly females (81,61%) with the majority were be-low 35 years of age (97,72%). Half of the participants experienced smell and/or taste loss during the COVID-19 infection; whereas (133;99.2%) recorded by CCCRC had olfactory dysfunction and (105,78.2%) had gustatory dysfunction. Males were with a higher significant rate of taste loss (P=0.009) whereas females with a higher recovery rate within the first two weeks after the onset than males. The Pfizer vaccine was sig-nificantly related to smell loss (P=0.038). All cells’ levels were reduced and signifi-cantly associated with a positive COVID-19 infection whereas the CD4 was signifi-cantly related to the Pfizer vaccine, loss of both sense and recovery time within 15 days. A high significant positive correlation was found between CD4 and Th2, IgG n in serum; was highly significantly related with positive COVID-19 infection higher than that of serum IgG s1. Noticeably, the IgA (s+n) in serum was negatively correlated with Th1 and Th2, could be detected in individuals with a duration from last infection >1-2 years and last vaccine duration > 6- 12 months. Blood group O was the most pre-dominant among this study participants (40%), followed by B, A, and AB with (90%) of them were RH+. A significant relationship between smell dysfunction and infected blood group A and RH+ (p =0.044, 0.038) while taste dysfunction was negatively and significantly correlated with AB group (r=-0.73; p=0.008). The FUT2 secretor showed a significant relation with COVID-19 infection and frequency. The majority of COVID-19-infected participants experienced a significant loss of both smell and taste with fast recovery within 2 weeks. Conclusions: The COVID-19 infection susceptibility and reinfection associated with FUT2 secretor status and greatly related to olfactory and gustatory sense loss. Sex variation was noticed with more predominant to females in dysfunction and faster recovery from dysfunction. The blood group A was associated with olfactory dysfunction and more with Pfizer vaccine. The low level of CD4 and an imbalance Th1/Th2 ratio made the recovered individual more susceptible to re-infection but the significantly high percentage of specific COVID antibodies followed one time of infection or booster vaccine dose gave their protection.

Abstract: Lymphomas are group of diseases caused by malignant lymphocytes that accumulate in lymph nodes and caused the characteristics lymphadenopathy.Occasionally, they may spill over into blood or infiltrate organs outside the lymphoid tissue The major subdivision of lymphomas is into Hodgkin's lymphoma and non - Hodgkin's lymphoma and this is based on the histologicpresence of Reed - Sternberg cells in Hodgkin's lymphoma. Aims of the study : The aims of this study were to determine the percentage of oral manifestations and identify the levels of salivary immunoglobulin A, interluekin - 6 and tumor necrosis factor - ? in lymphoma patients before the treatment and after receiving three cycles of chemotherapy in comparison with healthy control individuals.Subjects, materials and methods : The study included 25 patients( 15 male and 10 female ) with non - Hodgkin's lymphoma (B - cell type), 25 patients( 16 male and 9 female ) with Hodgkin's lymphoma and 25 ( 15 male and 10 female ) healthy control group with no signs and symptoms of any systemic disease and age, sex match with patient groups.Those patients were examined pre and post chemotherapy to see the oral manifestations and compared with healthy control group. Whole unstimulated saliva was collected to determine the level of salivaryimmunological markers which measured by Enzyme Link Immunosorbent Assay.IVResults : The percentage of oral manifestations was taste alteration in non - Hodgkin's lymphoma patients ( 36% ) and in Hodgkin's lymphoma patients ( 16% ) , followed by burning mouth syndrome ( 20% ) in non - Hodgkin's lymphoma patients and ( 16% ) in Hodgkin's lymphoma patients and lastly dry mouth was ( 12% ) in both non - Hodgkin's lymphoma and Hodgkin's lymphoma groups. In the present study there was no oral manifestations in both study groups before starting chemotherapy, and the mentioned oral manifestations incident after receiving chemotherapy regimens. The levels of salivary immunoglobulin A, interluekin - 6 and tumor necrosis factor - ? were significantly higher in pre - treatment patients in comparison with control group, and there was a significant decrease after chemotherapy treatment when compared to their base line levels in both study groups.Conclusions : The most frequent oral manifestations in lymphoma patients was taste alteration followed by burning mouth syndrome and dry mouth , and male patients affected more than females.The salivary immunological markers levels were higher in lymphomapatients than control, then these markers showed obvious decrease in patients after chemotherapy treatment

Abstract: Chronic kidney disease refers to an irreversible deterioration in renal function which classically develops over a period of years, the ageing of populations along with the growing prevalence of chronic diseases such as diabetes and hypertension is leading to worldwide increase in the number of chronic kidney disease patients, the patients suffering from chronic renal failure face oral health related problems because it affects the bone and soft tissue structures.During hemodialysis, blood contact with a foreign surface, such as a complement - activating dialytic membrane, promotes a variety of complex and interrelated events, leading to an acute inflammatory response.Cytokines are a broad and loose category of small proteins that are important in cell signaling, they are released by cells and affect the behavior of other cells, they are important in health and disease, specifically in host responses to infection, immune responses, inflammation, trauma, sepsis, cancer and reproduction.Aims of study : The aims of this study was to determine the prevalence of oral findings, salivary flow rate and evaluation of salivary immunoglobulin A, interleukin - 1? and tumor necrosis factor ? levels in chronic kidney disease patients on hemodialysis treatment in comparison with healthy control, and investigate if there is a relation between these salivary parameters (salivary flow rate, salivary immunoglobulin A, interleukin - 1? and tumor necrosis factor ? levels) in chronic kidney disease patients on hemodialysis (less and more than one year) and finally find the correlation between salivary parameters in patients group.Methods : Ninety (90) subjects were participated in this study, they were divided into two groups : Patients group comprised of 45 subjects undergoing hemodialysis with chronic kidney diseases; Control group comprised of 45 subjects with no history of any systemic diseases.Intra oral examination was done for each individual to record the prevalence of oral findings in chronic kidney diseases patients. Saliva collected was measured and levels of salivary immunoglobulin A, interleukin - 1? and tumor necrosis factor ? were measured by enzyme linked immunosorbent assay (Elisa).Results : The most frequent oral findings in chronic kidney disease patients on hemodialysis, in this study were dry mouth (77.7%), uremic breath (bad odor) (55.5%) , taste alteration (55.5%), angular chelitis (35.5%), mucosal pallor (26.6%), burning mouth syndrome (28.8%), staining of teeth (26.6%), oral ulceration (11.1%) and petechia and ecchymosis (2.2%), and the present study showed that no statistically significant differences (p>0.05) were found in oral findings distribution except angular chelitis which showed statistically significant difference (p<0.05) between chronic kidney diseases patients on hemodialysis for less than one year & for more than one year. According to salivary flow rate, the present study found that there was a significant difference in patients with chronic kidney disease in comparison to healthy control subjects, also statistically there was no significant difference in salivary parameters (salivary immunoglobulin A, interleukin - 1? and tumor necrosis factor ? and salivary flow rate) in chronic kidney diseases patients on hemodialysis for less than one year & for more than one year. The present study showed that there was no correlation between salivary parameters (salivary immunoglobulin A, interleukin - 1? and tumor necrosis factor ? and salivary flow rate) except salivary immunoglobulin A and interleukin - 1? showed positive significant linear correlation (r=0.368, p=0.006) and negative significant linear correlation between salivary immunoglobulin A and salivary flow rate (r= - 0.275, p=0.009).Conclusions : Cytokines may play roles in pathogenesis of chronic kidney diseases represented by increasing interleukin - 1? and tumor necrosis factor ? levels in saliva of those patients, the chronic kidney diseases patients on hemodialysis recommended comprehensive professional oral care and self - care instructions

Abstract: Background : Breast cancer is the commonest type of malignancy worldwide and in Iraq. It is a serious disease that affects the general health and cause systemic changes that affect the physical and chemical properties of saliva leading to adverse effects on oral health.Aims of the study : The aims of this study were to assess the oral health condition (including dental caries, oral cleanliness and periodontal health condition), to evaluate the changes in salivary flow rate and to assess the concentration of tumor marker CA15 - 3 and selected elements (calcium, phosphorus, zinc, copper, total proteins) in saliva and their relation to oral variables among breast cancer women in comparison to control group.Subjects, Materials and Methods : The total sample consisted of 60 women aged 35 - 45 years attending Al - Kadhemyia Teaching Hospital. Those comprised 30 women newly diagnosed with breast cancer before starting treatment and 30 women without clinical signs and symptoms of breast cancer as a control group.Diagnosis and recording o f dental caries was done by using DMFS indexaccording to the criteria of WHO (1987). Plaque index of Silness and Loe (1964) and calculus component of Ramfjod index for periodontal disease (1959) were applied to assess oral cleanliness. Periodontal disease was evaluated using the gingival index (Loe and Silness, 1963) and loss of attachment level (Ramfjord, 1959). Stimulated salivary samples were collected and salivary flow rate, salivary CA15 - 3, calcium, phosphorus, zinc, copper ions and total proteins were determined.Results : Results showed that caries experience (DMFS) was higher among the study group compared with the control group but the difference was statistically not significant. The mean values of plaque index, calculus index, gingival index and loss of attachment were higher among the study group than the control group with a highly significant difference (P<0.01).The salivary levels of CA15 - 3 in breast cancer patients were higher than that of the controls with a highly significant difference (P<0.01). All the correlations between salivary CA15 - 3 and dental caries and periodontal diseases were statistically not significant.The salivary flow rate was lower among the study group than control group with a highly significant difference (P <0.01). Higher concentrations of salivary phosphorus, copper and total proteins were recorded among study group compared to control with statistically highly significant differences concerning phosphorus and copper (P<0.01). On the other hand, salivary calcium and zinc were lower among study group compared to control group with statistically highly significant difference concerning zinc (P<0.01). All the correlations between the caries experience and salivary constituents in the study and control groups were weak and not significant except the correlation with total proteins in the control group which was significantly positive. Concerning the correlations of oral hygiene and periodontal disease with salivary constituents, the study showed that all the correlations were weak and not significant except the correlations between the total proteins with loss of attachment in study group and with dental plaque in control group which were significantly positive relations.Conclusions : This study showed that the breast cancer patients had poor oral hygiene and higher rates of periodontal diseases and dental caries, therefore special preventive programs need to be designed for this group of patients. Also the results of this study could support the concept that salivary oncentrations of CA15 - 3 might serve to be used in the detection of breast cancer and/or the po operative follow - up of patients under treatment for carcinoma of the breast

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.

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
