    Rheumatoid arthritis [RA] is a persistent inflammatory polyarthritis condition characterized by distinct immunological, clinical, genetic, and pathological characteristics, as well as remissions and exacerbations. This study was designed to estimate some Haematological and immunological parameters of Iraqi patients with RA. The data were collected between August 2023 and May 2024 from a total of 60 patients and 30 healthy controls. A serological test was assessed, including erythrocyte precipitation rate, and CRP. Complete blood count was measured using a fully automated quantitative Samsung device. The levels of IL-1β, IL-2, IL-4, IL-10 cytokines were assessed by sandwich ELISA. The result of this study showed that most RA patients were female compared to males. The levels of RF, CRP, and ESR test were significantly higher in patients with RA compared to the control group. RA patients showed statistically significant higher in WBC and Ptt tests while they had lower RBCs, Hb, and RDW compared to controls. When compared to healthy individuals, we observed that patients with RF had greater levels of cytokines IL-1β, IL-2, IL-4, and IL-10. RF patients had higher levels of IL-1β, IL-2, IL-4, and IL-10 than did healthy people.

    Back ground: It is commonly agreed that the commercially available heat-cured acrylic based soft lining material are far from ideal because of low thermal conductivity, poor tear and bonding denture base with the soft lining. Therefore, there is a need to improve such properties of these materials. Aim of the study: The purpose of this study was to assess the effect of adding different percentages of halloysite nanotubes into acrylic-based heat-cured soft denture lining material on the thermal conductivity, thermal diffusivity and some of mechanical properties including shear bond strength, tear strength, hardness and surface roughness. Materials and methods: Halloysite nanotubes (HNTs) with concentration of 0%, 0.75% and 1% by weight were incorporated into the soft liner material. Firstly, HNTs powder was dispersed into the monomer of the soft liner by using probe sonication apparatus and then, measured amount of the soft liner's powder blended into this suspension. One hundred and fifty specimens were prepared which were divided into five groups according to the tests to be performed. Each group consists of thirty specimens (10:control, 10: with 0.75% halloysite nanotubes addition and 10 with 1% halloysite nanotubes addition). Scanning electron microscope was used to show the dispersion of halloysite nanotubes within the polyethylmethacrylate soft liner matrix and energy dispersive X-ray spectroscopy analysis was performed to display the percentages of composite filler of both weight and atoms. To assess the chemical interaction between HNTs and the soft liner, Fourier transform infrared spectroscopy analysis was applied. X-ray diffractometer was also used to study crystal structures of nanoparticles. Moreover, some of the physical and mechanical properties of the HNTs / soft liner composite were investigated including thermal conductivity, thermal diffusivity, shear bond strength, tear strength, shore A hardness and surface roughness. The results of this study were statistically analyzed using one-way ANOVA, Dunnett’s T3 and Tukey highly significant difference tests at P IV value of > 0.05 was considered statistically non-significant, ≤ 0.05 was considered significant and ≤ 0.01 was considered as highly significant. Results: Addition of 0.75% and 1% of HNTs into PEMA soft liner showed a highly significant increase of thermal conductivity, while a non-significant increase of thermal diffusivity was observed. In addition, the results of shear bond strength after addition of 0.75% HNTs indicates a non-significant increase whereas for 1% recorded a highly significant increase. The results of tear strength (after addition 0.75% of HNTs were significantly increased in comparison to control group while after addition 1% were a highly significant increased). Shore A hardness registered a highly significant increase; yet, the results for surface roughness observed a non-significant change. Conclusion: The addition of HNTs into heat cured acrylic –based soft denture liner material could improve thermal conductivity, shear bond strength and tear strength properties, although thermal diffusivity and surface roughness were not affected as the concentrations of the nanoparticles increases. Yet, the hardness was highly significantly increased.

    Background: The mandibular foramen (MF) is a key anatomical feature of the mandible, critical for dental and surgical procedures due to its role in housing the inferior alveolar nerve, artery, and vein. Accurate localization of the MF is challenging, often necessitating the use of anatomical landmarks during procedures to prevent complications, such as nerve damage. Methods: This study analyzed the position of the MF using panoramic images reconstructed from cone beam computed tomography (CBCT). The sample included 56 dentate patients, comprising 22 males and 34 females aged 20-55 years. Linear measurements from the MF to various anatomical landmarks were taken, and statistical analysis was conducted using the T-test and ANOVA to assess the impact of gender, age, and side of the mandible on MF positioning. Results: The study found no significant gender differences in the distances from the MF to the mandibular notch (N-MF), the anterior border of the ramus (A-MF), and the inferior border of the mandible (I-MF). However, significant gender differences were observed in the distance from the MF to the posterior border of the ramus (P-MF). Age also significantly affected the P-MF distance, while side comparisons showed no significant differences in MF positioning between the right and left mandibles. Conclusion: The findings indicate that while most MF measurements are consistent across genders and ages, the P-MF distance varies significantly, necessitating personalized approaches in dental and surgical procedures to ensure precision and minimize complications. These insights into MF positioning enhance the effectiveness of clinical practices involving the mandibular foramen.

    This study aimed to assess the effect of halloysite nanotubes(HNTS) addition into soft denture lining material on thermal conductivity and thermal diffusivity, shear bond strength, tear strength, and surface roughness of the lining material. HNTSwith 0.75% and 1% concentration by weight (according to the pilot study) were added into acrylic-based heat cured soft denture liner. One hundred and twenty different specimens were prepared and divided into four groups according to the test to be performed. The thermal conductivity and thermal diffusivity of the soft liner/ HNTS composite were evaluated, shear bond strength, tear strength, and surface roughness were also measured, the results showed that there was a highly significant increase in thermal conductivity of the experimental specimens in comparison with the control specimens and a non-significant change in the thermal diffusivity of the experimental specimens. The shear bond strength between the soft liner and the acrylic denture base and tear strength showed a highly significant increase, but a non- significant difference in the surface roughness test was observed in all experimental specimens. Thus it can be concluded that the addition of HNTS can provide soft liner material with improved thermal conductivity, shear bond strength and tear strength while thermal diffusivity and surface roughness were non-significantly changed when the concentration of HNTs nanoparticles increased.
