Morphological & chemo mechanical analysis of exposed cervical dentin treated with three different desensitizing pastes (comparative in vitro study)
...Show More Authors

Background Obstructing dentinal tubules is a valuable approach for managing dentin hypersensitivity. Although various agents promote dentin remineralization, direct comparisons between theobromine, bioactive glass (BAG), and nano-hydroxyapatite (Nano-HAP) under simulated oral conditions remain limited. To fill this gap, this in vitro study aimed to evaluate and compare the effectiveness of these three treatments on exposed cervical dentin. The assessment focused on their chemical, morphological, and mechanical effects on dentin. Materials and methods Forty-eight human dentin slabs were obtained from the cervical portions of twelve sound premolar teeth. Baseline Raman spectroscopy and VMH tests were done to exclude outliers. All specimens were treated with 6 % citric acid (pH 2.0) for 2 min to remove the smear layer. They randomly assigned to four groups (n = 12): artificial saliva (AS), theobromine, BAG, and Nano-HAP. Evaluations were conducted using Raman spectroscopy (phosphate peak intensity at 960cm−1), Vickers microhardness testing (VMH), and morphological assessment under scanning electron microscopy (SEM). Results Theobromine, BAG, and nano-HAP groups demonstrated a statistically significant increase in Raman phosphate peak intensity (960cm−1) and Vickers microhardness values (p < 0.05), indicating surface remineralization. In contrast, the artificial saliva group exhibited a significant decrease in phosphate peak intensity and microhardness values (p < 0.05). Conclusion All tested agents significantly enhanced the Raman phosphate peaks and microhardness values compared to the control. Nano-HAP showed the highest potential for promoting the remineralization of exposed dentin surfaces. Within the study's limitations, it can be concluded that theobromine, BAG, and nano-HAP are effective in occluding dentinal tubules.

Preparation of PVC composite using reinforced Iraqi Bentoniet clay as a filler & study their mechanical and thermal properties
...Show More Authors

In this study , Iraqi Bentonite clay was used as a filler for polyvinyl chloride polymer. Bentonite clay was prepared as a powder for some certain particle size ,followed by calcinations process at (300,700,900) OC ,then milled and sieved. The selected sizes were D ~75 µm and D ~150. After that polyvinyl Al-Cohool solution prepared and used as a coated layer covered the Bentonite powder before applied as a filler ,followed by drying , milling and sieving for limited recommend sizes. polyvinyl chloride solutions were prepared and adding of modified Bentonite power at certain quantities were followed .Sheet of these variables on the mechanical and thermal properties of the prepared reinforced particular polyvinyl chloride composite

An experimental comparative study between polypropylene and laminated lower limb prosthetic socket
...Show More Authors

Most researchers concentrate their studies on the design, stress and pressure distributions of the prosthetic socket. A little attention is considered for the stiffness of the various materials of the prosthetic sockets. Prosthetic laminated sockets in Iraq are costly to be manufactured while polypropylene socket is relatively cheap in comparing with the laminates.

Experimental study is conducted to compare the stiffness of five prosthetic sockets made of different materials. Compression, three point flexural and tensile tests are implemented by the Testometric machine. The laminate sockets give better results in compression than polypropylene. Polypropylene gives good results in bending compared with the laminate sockets. When t

Salivary mucoepidermoid carcinoma, auclair vs brandwein grading system: A histopathological comparative study
...Show More Authors

Background: The grading systems of salivary mucoepidermoid carcinoma depend on different histologic and morphologic features. The aim of this study was to compare between Auclair and Brandwein systems according to their histologic criteria, and the type of cell predominant. Materials and Methods: Twenty-one case included hematoxylin-eosin (H&E) stained tissue slides that were diagnosed as MEC, originally categorized into low and high grade type regardless of the grading system, have meticulously undergone histopathologic review. The sample was graded according to criteria owing to Auclair and Brandwein methods. The predominant type of cells was determined by microscopic examination according to grade of tumor. Results: Regarding the

A Study of the inhibitory effect of Terpinen-4-ol on Amastigote Forms of Leishmania tropica within Macrophages of Mouse in vitro
...Show More Authors

It was recorded that Terpinen-4-ol has an anti-parasitic properties, so it will be noteworthy to intensify the studies about this compound.

This study aims to test the effectiveness of terpinen-4-ol on amastigote forms of Leishmania parasite in macrophages.

This effect was studied by adding increasing concentrations  of  Terpinen-4-ol to  culture wells containing mouse macrophages that were previously incubated with the promastigote forms of the parasites for 24 hours .Then, they were incubated for another 24 hours with increasing concentrations of Terpinen-4-ol.  After, Parasites were enumerated into macrophages in wells either treated with Terpinen-4-ol or in control wells.

Treatment with Ter

Thermal response of skin diseased tissue treated by plasmonic nanoantenna
...Show More Authors

The thermal distribution in the diseased tissue treated by different methods faces the problem of an uncontrollable defused heat. In the present article, we use a plasmonic bowtie nanoantenna working in the near infrared region to enhance the temperature confinement in the tissue. The Computer Simulation Technology Studio Suite package version 2019 was used to execute the design of both plasmonic nanoantenna and the tissue. Gold nanostructure and silicon carbide dioxide are the components the plasmonic nanoantenna in the bowtie shape. The results showed that the distance between the tumor tissue and the antenna is important to determine the intensity field where the maximum field is 5.9*107 V/m at a distance of 100 nm. The maximum
